When the design, as well as the principle of operation of the transmission, has become clear, you can proceed to the process of replacing the oil seal of the gearbox drive. So. Consider a step-by-step process:
Part selection
2108-1703042 - the original catalog number of the gear selection seal made by AvtoVAZ. The average cost of a spare part is up to 50 rubles.
Backstage oil seal of different prices
Alternative oil seals must be selected by marking, or rather by size in automotive stores.
The cost of such a product will not differ significantly from the original. So the very quality of such products is approximately the same.

Now that the issues of replacement and product selection have been considered, you can study the issue of the causes of failure.
Gearbox drive oil seal and the drive itself
So, let's consider what affects the condition of the oil seal:
What if replacing the oil seal does not eliminate oil leakage?
In this case, the shaft in the satellites is faulty. Because of this, there will be a backlash of the grenade.
