The oil seal with a rigid metal collar can be conveniently removed from the gearbox housing socket using an impact puller.
By hooking the hook of the impact puller onto the edge of the seal holder, we press the seal out of the gearbox housing socket.
Before installing a new seal, apply a thin layer of transmission oil to its working edge.
We press the oil seal into the gearbox housing socket using a mandrel (for example, with a tool head) of the appropriate size.
If necessary, we change the drive seal of the other wheel in the same way. The drive seals of the left and right wheels are the same.
We install the front wheel drive and fill the gearbox with transmission oil to the required level.
