1991 318is Differential complete rebuild kit?

[Ant131313]

Please help with links to a complete rebuild kit for a stock 1991 318is differential? I am needing all supporting characters including bearings too as well as the correct type of diff fluid? I am guessing I have a small case 4.10 but I don't know if it's LSD option or open.
Thank you guys!

Far as I know, you'll need to buy the parts separately. No- one packages kits for
BMW like they do for the domestic solid axle stuff.

And brace yourself- the parts add up fast.

No linky here. But if you get the part numbers off realoem.com, and then search yourself,
you'll see what I mean...

Strangely, Rockauto.com and other 'domestic' suppliers will have some of the bearings-
they are standard parts.

It's probably an open diff, LSD was an option on the 318is. Probably not worth it to spend the money rebuilding an open diff, and it's not exactly a DIY job unless you have the tools and are familiar with rebuilding diffs. Better to find a good used 4.10LSD.

I think It's likely an lsd. Most but perhaps not all 318is's will have the "s" on the tag.

Personally, I have never seen one without this feature

I used to see plenty at yards here in the Bay Area. I was very surprised when I found an LSD actually.

wow! so bimmer diffs charges between 215 and 315 for a clutch rebuild kit but only 200 for a ring and pinion? damn.

Thanks! We've done business with a number of forum members and have relationships with both Guten Parts and Kadunza.

It's not too hard or expensive to do yourself, as long as you're good at being organized and can follow step by step instructions. I believe I spent less than $500 doing a 4 clutch upgrade to my 4.10 with all new clutches, dog ears, bearings, seals, and machining. There is a good writeup online somewhere, just google BMW 188mm diff 4 clutch for instructions.

Neither of mine came with lsd. Really how much could that have cost to add as an option new?:(
