I have a e21 LSD that is leaking pretty badly.

I've noticed that the input shaft seal is NLA from real oem.

Does anyone have a good source for these seals? How about part numbers?

I have done my several hours worth of searching, but have not uncovered any good info. Maybe we should put together a FAQ page for this purpose.

Thanks

Edit... Of course I found the part number immediately after posting.

If I take photos of my seal replacement.. Can I have it posted as an FAQ?

For E21 seals and bearings, especially the later, larger bearings,

RockAuto has been a decent source.

CD's posted procedure is valid, but you have to be REALLY careful

not to increase the crush on the sleeve, and that's not easy. Best would

be some sort of 'ring wrench' that would let you see the edge of the nut

and the end of the shaft as you tightened it...

One other thing- if the bearings are worn or out of adjustment, that kills

an old seal. And it will kill a new seal, too...

Having said all that, changing the bearings isn't an impossible job, if you

have a press and a way to make a couple of pressing arbors...

what I've found,
