Can anyone tell me how to tell if an E9 diff is limited slip or not by looking at it from the outside? Also, is there a way to tell what amount of lock up it has?
Are there any practical checks to determine a diffs state of wear with it on a bench?
Lastly does a diff from any E9 fit any other E9 or are there differences?
Thanks

Locking diffs generally have an S stamped on passenger side of case with the ratio such as 38/11 which is a 3.45 ratio. All e9 side loader diffs are interchangeable. Can't answer your other questions.
 
Thanks

Thanks to all for their help. I was told by a former owner that he had one, but I want to be sure that it really is an LSD. Especially as he told me that all Coupes had them, which they don't.

Hi all

I thought a Limited slip diff would require a certain (depending on the design) speed difference at wheels to lock up the diff, and it would act as a regular diff at normal cornering. You would have to turn the free flange really fast I guess.
Am I wrong?

cheers
