Silver Fox 43 Report post Posted January 3, 2009 I have 2 LSD's to sell, a 3.46 and a 3.64, both good working condition out of E28's. They will fit E30 cars, you need a medium case E30 diff and just swap the output shafts and the back plate, very easy. Make an offer? Just kidding, I'm after $850 each, or will swap for an open medium case 3.91 and $700 if you wish, you can even keep the back plate and output shafts if you want.

Apex 693 Report post Posted January 19, 2009 Excuse my ignorance but how would one know if there diff was medium case and what the ratio is? Quote Share this post Link to post Share on other sites
Guest FrantiC Report post Posted January 19, 2009 (edited) Medium case come with 325i, 320i usually have small case ones. I would try find pictures but I can't atm. You usually tell by looking at it, because the actual case on a small case diff is smaller and the flanges stick out to the side more. Ratio is on a metal tag, bolted to one of the bolts on the rear case of the diff. Usually it will have something like 3.64 (then some numbers after it). If it has "S 3.64" it is an LSD. p.s fitting my clutch pack today, that I got from silver fox, into my 3.64 diff. God damn those bolts on the ring gear are on there tight....

Guest FrantiC Report post Posted January 20, 2009 (edited) Good luck, got mine undone with a big air ratchet, were very tight. Got my 4.1 LSD back today to fit. Yeah I couldnt manage to do it with my air ratchet and big compressor, Took it down to BMW and they did it pretty quickly. Pain was getting that speed sensor ring back on it. It was very very tight to, I can't even spin the input shaft by hand once I reassembled the diff. But she goes alright, Took it for a spin just before. Very nice Edited January 20, 2009 by FrantiC Quote Share this post Link to post Share on other sites
