Jili MK (Geely MK) is a Chinese representative of the Class C, which is the development of GEELY Automobile companies. In recent years, the Chinese auto industry has committed a real breakthrough in the automotive industry. One of the main components of the popularity of this model is the design - the exterior of the car is not typical for the Eastern manufacturer and more resembles the "American". Compare this car with the Americans, Japanese or Koreans is not worth it, since they are standing above for the quality of assembly and components, but this model has one parameter for which he exceeds all its competitors, and this is its price, and this parameter has always been One of the main when choosing a car. But, here, as the low cost of the car, it affected his reliability, and what should be paid attention to when choosing Gili MK with mileage on secondary market, now we will try to find out.
A bit of history:
In the inner Chinese market, the premiere of Jil MK took place in 2006, and in the CIS, this model appeared only in the middle of 2008. The basis for the development of the car was taken the first generation of Toyota Yaris, also, the motors from Toyota are used on the car. Geely previously bought these engines from Tianjin Industrial (FAW), which has a Toyota license. In January 2010, at the factory of the automotive company Derways in Cherkessk (Russia), car production for the CIS markets was launched. Before that, Jille MK was delivered to the car dealerships straight from China. In 2011, Geely conducted a rebranding, as a result, the car was called Englon MK, and MK Cross was renamed English Jinying Cross. Rebranding was conducted in connection with a new marketing strategy aimed at updating and raising the image of the brand. In 2015, GC6 came to replace the Gili MK, which is a deep restyling.
Weak places and disadvantages of Jil MK with mileage
Metal, like paintwork, very thin, because of this, chips and dents appear even from a small pebble, leaving from under the wheels of the oncoming transport. The body is weakly opposed to aggressive impact ambient, because of what the rust on the car body appears after a couple of years of operation. The faster of all corrosion appears on the bottom of the car (additional processing of anti-corrosion means is required) and in the places of chip. Also, the rust characters can be found on: front doors (under the seal), the hood and lid of the gas tank (in the castle area). The protective glass of fog lights is often cracking when they are used in cold and crude weather.
Engines
Jille MK was published only by gasoline power units - 1.5 (94 hp), 1.6 (107 hp). The most common engine in the CIS is the 1.5 liter unit, which was assembled by Toyota's license (copy of the 5A-FE motor from). If we talk about his reliability, then, in general, the motor is not bad, but, a couple of weak points in it was still identified. First of all, what you need to pay attention is the timing belt. According to the regulations, it does not require replacement to 60000 miles of run, but, as the operating experience has shown, after 40,000 km, cracks appear on it, also may not be enough tooth pairs, to explain to which consequences it can lead, I think it is not worth it. For lovers to carry out repairs in their garage it is worth considering the fact that to replace the timing belt will have to remove the right engine support.
The owners are not rarely faced with a nuisance when not a heated engine begins to trim, good, to solve the problem you can do without a trip to the service - you need to change the spark plugs, high-voltage wires or ignition coils. If the manipulation data does not give a positive result, you will have to make valve adjustment. To perform this procedure, you should turn to an experienced specialist, since incorrect adjustment of the valves can lead to their "clamp" after 40-60 thousand km of run and followed by a squeak. You need to remove high-voltage wires very carefully, since there is a high risk of their cliff.
On vehicles with a mileage of over 50,000 km, the coolant leaks appear through the heating of the throttle. If you cannot eliminate the defect in a timely manner, it can lead to a premature failure of the regulator idle move. The main signal of the fault of the regulator will be: difficult launch, the motor stalls immediately after setting and starts only when the gas pedal is pressed. The new regulator will cost 20 cu, but you can save a little by setting analogue from Chevrolet Niva (8-10 cu).
In the warm season, it is necessary to closely monitor the engine temperature, most often the engine overheats with a long motion at a speed of 80-100 km per hour with air conditioning on. The main reason is not to turn on the cooling fan, in bad contact on the wiring terminals and the late opening of the thermostat. The ability to control the engine temperature and preventing it overheating is complicated by the fact that the temperature sensor may produce incorrect data. If you fail to warm the engine to operating temperature During a long time, most likely the problem is associated with the overlap of the thermostat in the open position.
Most copies on mileage of 80-120 thousand km have to change the gasket of the cylinder head block, the reason is the root of the gasket of the GBC. On the same mileage it is required to replace the pump. Cooling radiator is subject to corrosion. The signal of the problem is the emerging spots of red-colored in expansion tank. With the arrival of cold weather in places of plastic and metal compounds can begin to flow the cooling radiator. On the mileage of 80-100 thousand km, it is necessary to replace the front oscillation of the crankshaft (oil leaks appear). Once in 60-80 thousand km is required to replace the oil pressure sensor. A little less resource (40-60 thousand km) possess the airbags of the engine and the checkpoint. Many owners raise on big flow Fuel, B. mixed cycle 8-10 thousand km, and it is much more than the manufacturer promised.
Transmission
Jil MK was equipped only with a five-speed manual transmission. To the diagnosis of transmission, it is necessary to take much carefully. The main ailment with which you have to face the owners, is the briefness of the bearings of the primary and secondary shafts. Most often, the owners of cars with mileage of 50-70 thousand kilometers are addressed to the service with complaints of extraneous noise in the box. To troubleshoot the malfunction will have to spend 100-150 USD. They are not famous for durability and glands of the semi-axes, as a rule, leaks of oil appear after 30-40 thousand km of mileage. On mileage of 60-70 thousand km, the main clutch cylinder is required. To save a slightly cylinder can be repaired using a special Remkomplekt. When using low-quality oil, with the onset of cold, it is difficult to switch transmissions. The grip with careful operation is capable of listening to 80-100 thousand km (set of new clutch with released Bearing It will cost 40-60 cu).
Features and disadvantages of running jili MK
The Jil MK is used standard for this car class suspension: in front - MacPherson, rear - beam. As for the reliability of most elements of the chassis, the situation is not so optimistic here. Most often, the replacement of the stabilizer racks is required, in non-accurant drivers, they go less than 10,000 km, with careful operations can be held 15-20 thousand km, bushings up to 40,000 km. Shock absorbers serve 50-60 thousand km, but, there are often cases when they had to change and after 30,000 km, the benefit of their price is not too large to 50 cu. PC. Front hub bearings, levers I. ball supports May be pleased with mileage of 70-80 thousand km. Shruses can last up to 100,000 km. To less often face the repair of chassis, many owners when selecting spare parts prefer interchangeable details from different models Toyota.
Lufts in the steering rake have a place to be even on almost new cars, the reason lies in the poor-quality assembly of the node, good, to eliminate the defect it is enough to pull it out. The resource of the rail is not much different, from a similar detail, most of the Japanese and Korean manufacturers (100-150 thousand km). Buying a new rail will cost 150-250 USD. Steering tips require replacement every 50-60 thousand km, traction times in 70-80 thousand km. There are problems and with brake systemThe main one is corrosion of the piston of the brake cylinder, which leads to the jamming of the brakes. Also, the rear cylinders require special attention, there were cases when the brake fluid appeared on them.
Salon
The quality of assembly and materials Salon Gili MK cannot boast, and thanks to the use of hard plastic, crickets feel at home. If rattling comes from the steering wheel, it is necessary to check the degree of tightening of the bolts of the airbag (unscrewed). The front armchairs at intensive operation can be wipe after a year, taking heating elements behind them. If you neglect the replacement, everything can end fire. Due to poor-quality sickness windshield and the constantly flying rubber plugs on the bottom, water appears under the rug of the driver and the front passenger. Also, after heavy rain, the puddle may appear in the trunk, the reason is low-quality seals rear Lights and rear shock absorbers supports.
As for the electrician, then, most often, unpleasant surprises are heated rear glass, Mirrors and climate system. Many owners complain that the air conditioner does not cope with its responsibilities even in cool weather. Freon leaks appear on the mileage of 80-100 thousand km, the air conditioner compressor can jar on the same mileage. At the most inappropriate moment, the stove fan can be stopped, the reason is the failure of the revolt controller relay. After 100,000 km, problems with the voltage regulator begin (repair or replacement of the generator is required), as a result of which the battery stops charging. Due to the failure of the circuit board of the electric motor, the backlight of the instrument panel stops working.
Outcome:
Despite significant progress in the automotive industry, the Chinese auto industry still does not reach the level of Korean and japanese manufacturers And Jili MK is no exception. It is impossible to call this car, since a small resource of some parts is justified by a low cost car, cheap repair and maintenance.
If you are the owner of this car model, please describe the problems that you have to face during the operation of the car. Perhaps it is your feedback that will help readers of our site when choosing a car.

21 ..Geely MK / Cross. Reduced coolant level
| List of possible faults | Diagnostics | Elimination methods |
|---|---|---|
| Damage to the radiator, expansion tank, hoses, weakening their landing on the nozzles | Inspection. Tightness of radiators (engine and heater) is checked in a bath with water with compressed air under pressure 1 bar | Replace damaged details |
| Liquid leak through coolant pumping liquid | Inspection | Replace the pump |
| The cylinder head gasket is damaged. Block defect or cylinder head | On the oil level index, an emulsion with a whiten tint. It is possible to appear abundant white smoke from the muffler and oil spots on the surface of the coolant (in the expansion tank). Coolant drums on the outer surface of the engine | Damaged details Replace. Do not use water in the cooling system, pour the cooling fluid corresponding to climatic conditions |
Causes of drop drops Coolant in the expansion tank (decrease in antifreeze level)
The change in the level of coolant is quite natural. On the cold, level decreases, and on a heated engine, the level rises. Similarly, the level changes and depending on the air ambient temperature. IN winter timeThe volume becomes less in the expansion tank, and in the summer - more. But that if you have noticed a constant decrease in the volume of fluid in the tank. There are no other reasons for reducing the level of antifreeze that are caused by a malfunction of certain nodes in the cooling system.
The first thing to make a car owner to clarify the reasons, determine the place of leakage. To do this, when you put the car into the garage or parking for the night, put the clean white cardboard under the hood. In the morning, carefully look at whether there is a liquid on paper and in which area. Usually, it happens either under the radiator, or under the engine, where the pump is located (water pump) pumping antifreeze through the system.
Very often the cause of the leakage is unhappy clamps on the hoses. With a flashlight, inspect podcast space And if there is an opportunity to drive the car on the overpass or a hole to make a good inspection under the hood. Browse the places where the clamp holds the hose. If the reason is in the clamps, then you will quickly find a constantly wet place, from where antifreeze seeps. In this case, it is necessary to replace the clamp to the new and check if there is no leakage after this. If all the choms are dry, and the reduction in the level of antifreeze continues, then check the pump. Often, this pump pumping antifreeze on the system fails, especially if it is poor-quality production. Pump replacement is performed every 50-60 thousand km., Although many car owners are waiting for it when it fails and only then turn to the car service. It is possible to notice the malfunction of the pump on the following features:
- in the area of \u200b\u200bthe pump and the drive belt is constantly wet;
- The stove in the cabin has become weakly warm;
- Remove drive belt And try to turn the pulley. Observed pulley - a sign of a malfunction;
- The appearance of a well-visible gap in the pulley drive is the most likely sign of the fault of the pump or the fact that the pump will soon fail.
A characteristic feature that the pump has already failed is, except for antifreeze leakage, a permanent knock while running the engine. The source of the knock is the faulty pump bearings.
If all the above features are not selected, check the proper function of the radiator. Indirect signs of the radiator breakdown are:
- antifreeze spots under the hood in the radiator area;
- constant fogging of windshield;
- In the area of \u200b\u200bthe front passenger, the constant appearance on the semi oil spots.
In case of detection of these signs, you need to repair a hundred.
Reducing the level of antifreeze can occur in case of breaking gLP gasket. When breakdown in this part, the coolant begins to fall into oil channels. A characteristic feature - the appearance of white smoke from exhaust pipe And the appearance of on oil probe Transparent bubbles. When identifying these features, contact the car service and not to operate the car. Finding into the oil, the antifreeze reduces its lubricating properties that over time it can cause an overheating of the motor and its breakdown.
Evaporation of antifreeze and other reasons for his leakage
Antifreeze is a substance that is used in the cooling system of vehicles, differs in high boiling point and low freezing temperature. Now there are three main colors - red, green and blue.
The basis of such a composition is a glycol and aqueous mixture, which determines the property of antifreeze does not freeze under negative temperatures. Among domestic producers, the most common products based on ethylene glycol are. However, an aqueous solution of such a substance is quite aggressive with respect to some materials. cooling system Auto.
To prevent damage to the details, the composition of such a substance also includes various additives: anti-corrosion, stabilizing, antimensive.
Common breakdown of the cooling system
The most common breakdown of the cooling system of the car is to reduce the level of antifreeze. Signs of such a problem are:
The output of a large number of steam from under the hood;
White smoke, which comes out of the muffler;
The stove reduces the air temperature in the cabin, and does not increase it;
Dashboard signals the overheating of the engine;
The thermometer in the car reached its maximum value.
Sometimes even a few signs appear at the same time, in this case the car needs to immediately drown out and provide it with maintenance per service station.
Why does antifreeze level decrease?
Reducing the level of antifreeze in the coolant tank is quite common in our time phenomenon. This may occur for several reasons:
In the cold period of the year, the cooling substance has a property to decrease in volume. Therefore, in the winter to top up such a substance follows more often than at another time.
Liquid passes into cracks and tank slots or its covers. Detect such problems is quite difficult, because the cracks are appearance Can resemble ordinary scratches. However, for a slight antifreeze departure from the tank it can be enough.
Leaves from Bachka
Depressurization of various compounds of the cooling system or damage to its tubes and shlage. Also, the leakage occurs with the thermostat laying.
Different radiator breakdowns can also cause reducing the level of coolet fluid.
Radiator flows
Another reason for the care of antifreeze from the vehicle system is its evaporation. The composition of any cooling fluid includes water, which, even despite the tightness of the cooling system, gradually evaporates from it. Experts note that reduced fluid levels in such automotive system An approximately 200 grams between two neighboring scheduled maintenance is the norm.
Thus, even in the absence of any damage, antifreeze is gradually evaporated from the car cooling system, although this happens in very minor volumes.
If the cooling substance goes fast enough, the reason lies not in evaporation, but in some other problem, so it should be immediately sent for a hundred for professional help.
If there is no possibility to use the services of a car service with "care" of antifreeze, determine the cause of such a problem can be tried independently.
First of all it follows when disabled Engine Check the oil - remove the probe and thoroughly examine it for the presence of traces of some other fluid, except the oil.
After that, you should start the engine and leave it to work until the fan is triggered. At the same time, it is necessary to monitor the cooling system - there are no liquid drops somewhere, especially in the locations of the joints and hoses. With a small probability, the problem can be in the radiator, but it is very difficult to determine this on its own.
Also, it will be useful to check the tank closing density. Usually, in this case, light steam comes out from under the hood, and the characteristic traces of the fluid evaporate will remain on the tank.

The gearbox is one of the most complex mechanisms in the entire car. With it, the complexity of the design can be harvested except that the engine. This is the reason why the box is often even more expensive power aggregate. To understand all the features of this process, it is enough to consider the gearboxes from the inside - this will give an understanding of the high complexity and the technologicality of all the mechanisms built into the case. Repair should be made exclusively professional, otherwise the unit will not be able to undergo a sufficient amount of time. It should be understood that the reliability of the car's trip depends on the quality of the box work, the convenience of its operation and the physical ability to go to long-distance travel without fear of terrible breakdowns.
The box can show a variety of trouble during operation, but one of the most common manifestations of breakage is a hum in the gearbox. The hum may be of different intensity, tone and strength. You can barely notice it, and sometimes the buzz is worth such that overclocking the car to high speed or turn the engine to high revolutions Just do not want. Sometimes such a hum is only evidence of any technological features boxes. Sometimes it occurs after repair when the details are not fully suitable for each other. IN this case It is not critical, but you can remove it only with repairs. Let's look at the reasons that make you feel the growing discomfort when traveling is not a car and feel unpleasant sounds From under the hood.
The box of the machine - the rumble is definitely not good
If you have an automatic transmission, a variator or robotic mechanic with automatic switching, the buzz you definitely does not foreshadow anything good. On any service, one disassembly assembly your box will cost fabulous money. Today you will not too much please spare parts. Sometimes it is better to listen to the hum, than to hear the price that is necessary to eliminate it. Take advantage of specialists to diagnose gearbox, but remember that the complete diagnosis of your automaton is possible only if the box is dismantled. Most frequent reasons The hum of automatic gearboxes are as follows:
- in the usual machine or in robotic box One of the elements of the main pair, giving the backlash in work;
- the gears do not fall on each other in normal modes, there is an excessive friction of the mechanisms in the box;
- for the Gul Variator, almost accurately means death or the need for propellant - stretching of the main working mechanisms is not so rare;
- also, the box can buzz due to poor mounting semi-axes, which causes the backlash on the connecting places and a rather strong hum;
- often bury the bearings, which failed, they will definitely show themselves in the near future;
- erased teeth on the leading gear or on the shaft will mean the presence of a backlash and a constant hum on one or more transmissions.
Often, some other troubles with a gearbox begin to occur with the roiler. For example, the PPC begins to throw away one of the gears after you release the gas pedal to slow down. This can be to blame for a fork gear, but it all depends on the box, its type, designs and other features. If for the mechanics such a problem is quite simple, then for the automaton, yielding transmissions in unauthorized mode means the impossibility of the operation of the car. Otherwise, the trip on such a car will be unsafe. So always follow the sounds that appear from the machine and contact the service center to eliminate them.
Mechanical gearboxes - hum for many reasons
In the mechanics, the causes of the occurrence of the roast in the gearboxes are not less than in automatic boxes. Need to remember that mechanical box Pretty gentle, loves moderate operation and the absence of sharp movements. This also applies to sports boxes that are most protected from damage at sports drive modes. Nevertheless, such boxes are considered more reliable and endless than automatic types. This is a rather controversial truth, because there are different machines and there are various mechanical PPC. Many car enthusiasts prefer mechanics for a rather low recovery price. Although it depends on which reason caused a hum in the gearbox:
- worn or unequal replacement of the elements of the main pair - hum may continue for a long time without negative consequences, but in the end, the box will fail;
- the driving bearings were wear out - they will be just a few weeks of active exploitation and break down, caused the cause of not too pleasant consequences;
- gears gears - if the roe is heard only on one transmission, the culprit of such trouble is the gear of this transmission;
- the poor-quality assembly of the box is often the reason that humbles arise due to the inconsistency of the shaft hit on the gears;
- the poor work of the transmission mechanism leads to the fact that the inclusions are inaccurate and uneven;
- often, individual and unforeseen problems occur in mechanical boxes, which are diagnosed only after disassembly.
Such troubles are possible in every car. Sure, domestic cars become more frequent visitors to professional service stations. But often and expensive technological foreign cars come to the station with the issues of the gul of the gearbox. It should be noted that in most cases high-end cars do not provide such problems. They are fulfilled as high quality and can serve for many years without any questions. But in some cases the culprit of the box breakdown is not an engineer or a collector at the factory, but the driver himself.
What should I do if the buzz began to come from the box?
The best solution in this situation is to immediately wrap at a good station. maintenance For information on the nature of this hum. If a specialist after diagnostics tells that the main pair of depreciation began, or other gears of the box, you can safely ride a few more weeks, collecting money on repair work. But remember that the wear of the shaft of the main pair is sometimes a negative impact on the state of all gearbox mechanisms. So you can easily bring the situation to the fact that your box will have to send to overhaul or even replacement. The box repair algorithm is:
- bring a car to high-quality service with a sufficiently large number of specialists and good repair equipment;
- book to start disassembly and complete detailed diagnostics of the gearbox to determine problems;
- when identifying a problem, estimate the cost of restoring the machine and the potential repair of your box;
- take the decision based on the proposed facts and the information provided from the specialists;
- order repair of the gearbox of the professionals that you completely trust - it is impossible to allow poor repair quality;
- install only original expensive parts inside the box, as they will be able to last for a long time and possess a guarantee.
One of the most expensive processes in the transfer of the gearbox is disassembly and diagnostics. Then everything is performed by democratic rates of a hundred. You need to remember this when choosing details for your gearbox. It is best to take advantage of the original factory versions of spare parts to completely exclude trouble in the near future. So you will save on subsequent repairs and can simply make the necessary tasks for one disassembly process. It should not be saved on the details and on the quality of the work done, as this may adversely affect the operation of the aggregate. We suggest to consider the reasons for the Gula in the box, which experts say:
Let's sum up
Many motorists face such a problem as the gear of the gearbox. It can be an automatic or manual box, each version of a modern robot or such a fashionable variator. There are dozens of diseases of technical components and aggregates that can negatively affect this part of the configuration of your car. Therefore, you should pay special attention For those features that the checkpoint provides for operation. If you simply miss the moment of starting the burying of bearings or other parts, then you can soon be the cost of expensive without the possibility of moving in the car.
There are many types of motorists. Some want the ideal work of their vehicle, others are pleased with the fact that while the car goes, and nothing to repair it. But most owners vehicle They want the basic nodes of the machine to work well and efficiently. Therefore, do not neglect the good diagnosis to find out which part of the box causes an unpleasant hum. Most likely, after such a diagnostics, you want to recover the node. And your car had such problems with the checkpoint, which caused an unpleasant hum?

Howl gearboxes - quite often an emerging phenomenon. How to properly digitize and make a decision on the need to repair.
Oil: maybe the reason in it?
There are several reasons why the gearbox starts to swell. The first, most common, oil level in the box. Many motorists do not give the meaning of the need to control the oil level in the gearbox. This leads to oil starvation in the main fifth transmission, which is above the rest. Due to the lack of oil, bearings begin to overheat and fail. This is accompanied by high tone, which manifests itself when moving on the fifth gear. There is such a disease overflow by 100 - 200 grams transmission Oil Above the level with its constant control.
Some may say that overflowing oil will cause it through the sealing compounds. That this does not happen, it is necessary first of all to clean the Sapun, and in the second, pour oil parts, gradually. For example, first 100 grams, and after some time, in the absence of leaks, still so much. You can also add a second seal on the Kutis kole.
The next, not less common cause of the sound of the gearbox is the poor quality of the transmission oil, filled into the checkp or incorrectly selected. If we talk about domestic cars, For example, the use of the APIGL-5 category oil pumps in the transmission pumps, leads to rapid wear of synchronizers, which will cause noise of the box when switching. Therefore, it is necessary to use the transmission of the APIGL-4 class. Domestic oils of this classification are quite difficult to find, so you have to use lubricants of foreign manufacturers. But their use allows you to significantly extend the service life of the gearbox, avoiding different sounds when moving.
In addition, the insufficient or excessive viscosity of the oil used also affects the wear of the box parts and the availability of sound when it works. For example, a strongly thick oil with a viscosity of 85W-90 creates a solid film, protecting the gears from wear, but it makes it difficult to access lubrication to some details of the box, which may suffer due to oil starvation, prematurely fail. The gear shift will also be difficult due to the need for synchronizers to squeeze the surplus oil, which will again lead to the rapid wear of the parts. The first sign is strong dense oil It will be on the cold and its disappearance on a heated unit.
Too liquid oil will cause the opposite effect, in which the oil film disappear will occur, accelerating wear of the gearbox parts, which will be accompanied again and the hum.
It is necessary to closely carefully approach the choice of transmission oil according to the recommendations of the manufacturer and experienced servicemen.
Additives to the oil: Is it possible to do without repair?
If the oil change does not help, the gearbox will, then it is necessary to repair the unit. Many can say about adding additives, but it does not help 80 percent of cases. According to the reviews of many motorists, adding additives can only force or not fully muffle sound support, but I will not finally solve the problem.
Chemically active substances contained in the additives-revitalizes form a metal-ceramic layer on the surface of the worn gears and bearings, which, according to the manufacturer, restores the geometry of parts and compensates for wear. Of course, if the turn of the gearbox is heard almost noticeably, it only began, the addition, for example, Hado, may well delay the problem with the repair of the checkpoint. But may not help if the problem is already so much, and the wear of the assembly units is significant. Then the repair is accurate.
Diagnosis and repair
As for the repair of the CAT, it is very important for the start to conduct the correct diagnosis. possible malfunction Aggregate, try to determine why the box gives howl without removing the aggregate. Typically, the box will not work in all modes, but at some speeds. If the howl accompanies movement by 1,2,3 transmissions, then this usually indicates problems with the bearing connecting the primary and secondary shafts, more precisely, its wear. The only way out will be replaced. But there is a small nuance - if a needle bearing, not having a clip, then simple replacement The needles may not help. At the same time it will be necessary to replace the shafts. And this is a serious repair.
It is also possible for the presence of a work pair of gears located on the primary and secondary shafts of these gears. Or with poor factory processing and installation after repair. One of the characteristic traits of the wear of the gear, it is a war-loaded load and its decline in the absence of traction. Worn bearing will be noise anyway - there is a load or not. But it is possible to determine exactly the causes of the transmission only by showing a specialist if the repair is done with your own hands.
If you are attended by the 5th gear, the priority, what needs to be done is to check and add oil into the unit if necessary, as already mentioned earlier. But if it does not help, it is most likely necessary to replace the gear of the fifth gear. This is determined by opening the box. Previously, by sound at high speed, it is possible to determine the cause - with a frankly worn out of the gear, with a peak of over 100 km / h - most likely, the bearing.
If the front-wheel drive car is working on all transmissions, then the high probability of wear of the primary shaft bearing. But his replacement often does not lead to a positive result, therefore it is not recommended to change it in the presence of a minor war.
Or maybe it's not a box at all?
Conducting the diagnostics of the gearbox must necessarily consider the fact that in the presence of a constantly increasing warning on all transmissions guilty in origin of sounds can be not only a gearbox. On models with a classic drive, the source of war can be reducer rear bridgehaving a conical hypoid gear. With the wear of the teeth, the gears or with a significant louche of the bearing bearing will accompany all the modes of movement. Similar symptoms also accompany all-wheel drive car With malfunction front Bridge. The sound will come from the center of the cabin, and is observed with loads.
Summing up
Doing the repair of a singing gearbox must be important to remember the poor quality of the manufactured aggregates and spare parts. It is not significant that the purchased parts or aggregates are new - defects can be in them. Sometimes, with minor noise in the checkp. It is easier to add the sound of the radio tape recorder in the cabin than trying to eliminate cricket several times to go through the box.
Good luck on the roads!
