I had my car up on the rack. How do I tell if I have a LSD? I think I do because when I was trying to tell I couldn't rotate the left wheel more than X degrees without moving the right wheel. But shouldn't there be a tage or something? I didn't see an S stamped on it like the e21s

in neutral, spin the back wheels forward, if the other goes the opposite direction, i belive its a open (non LSD) and if it goes the same its a closed (LSD)
someone correct me if i am wrong, that is just off the top of my head.

My car has issues. The rotors are all rusty and the brakes are grabbing. On my e21 if I rotate one wheel the other rotates also in the smae dirrection, but like I said this car has issues. If I am lucky I will have the rack this weekend and I'll get the rotors off and drop them off to get turned while I'm puting the gas tank back in.

I loved my E21. Euro spec 320 with Hartge goodness. An 18 wheeler tested the side impact beams I had put in... and they passed.

MMMMMmmmmmmm Hartge.

My e30 has an LSD. When I was putting the drive shaft back in, enough rust had wore off the rotors to allow them to spin free. When I turned the drive shaft, both wheels spun. It was that motor week video that scared me. They said it was an option.

Theres a little metal tag on one of the diff cover bolts that says if its an LSD or not.
It'll say S4.10 is it's an LSD a little sand paper will make it easier to read.
Luckily both my cars had the LSD option.
