re: Leaking Differential

Sean:

Assuming you have an e36 M3............I have a 2000 MRoadster that experienced differntial failure through a seal leak on the right side where the stub axle connects to the differental.  My story starts with a torn and leaking CV joint on the right rear axle at about 19000 miles. The axle was replaced under warranty.  Approximately 3 months later at 23000 miles, I start getting a drip of differental fluid from the car while it is sitting.  It also appeared to be coming out while driving.  Another trip to the dealer tells me that the circlip that hold the gears in place is missing and the gears have moved out of center and worn which wore a hole in the seal.  I need a new (that is re-manufactured) differential.  Again replaced under warranty.  So I am not sure if this helped on giving you the cost......but lets you know someone else is having BMW differental problems.

I would get a re-manufactured unit installed unless you can take the car to someone that can be trusted to do internal differental repair work.  Sounds like you most likely have some internal problems in addition to a leaking seal.  Good Luck!!!
