Hi Don.
Well my leak is the seals themselves as you can see in my gallery photos.
I just jumped into the project tonight and will say that I am having a few problems.
Like the Haynes repair book says to drain the gear
oil. Sure, but it does not tell me what size hex key to use. So I go to Sears Hardware and find a 17mm that looks good and get home to find out that its to big. On my return trip to Sears I phoned the BMW dealership to find out the correct size (I know, should have done that the first time) and found out that it is a 14mm hex key. Low and behold Sears hex key stop at 12mm. They have a 17mm but none in between. I called with no luck at Ace, Pep Boys, Napa and finally the 2nd Napa store I called had one in stock. 75 miles on my car (not the cobra) driving around trying to find one.
I also needed some Torx sockets to remove the drive axles and when I started this project I found out that someone previous to me has stripped the bolts!! On one side I got 4 out of 6 removed and I am going to try the other two again in the morning.
Anyone know how to get stripped Torx bolts out??
It's also a pretty tight fit under the car as I do not have a lift and it looks like I may have to take the sway bar out also?? Don't know yet.
Anyway, I am a fairly handy guy but with no literature on how to fix our specific cars it looks like a bit of trial and error.
Good luck with yours Don,
Jack
