hi gizmo....i have a E30 325is (or it used to be one.....I am the 50th owner)......the diff seems to be locked. When I take a bend I can hear the inside wheel slipping...what can the matter be?

Sounds like the diff has been welded solid...If you need a replacement then let me know...

RE: BMW Differential Tutorial, with pics.
Hey Gizmo,
hows it looking with the M5 diff cover, has your supplier gotten back to you yet? just wanna know. cause my gearbox is going in on saterday morning.. clutch will only be ready then.. and then if we can get the cover by then, I can get him to do the diff at the same time, otherwise I gotta take the back again for the diff cause the driveshaft will prolly need to be modded again...

Greetings Bro.

They supplied the wrong one, Im waiting for them to find the right cover, it may be a 2nd hand one if they can't get new. I will give you a shout as soon as I have it.

Nice thread!
Can you get seals for the two output shafts for an E39 M5 diff?

RE: BMW Differential Tutorial, with pics.
Guys, sorry to jump on this thread, but I thought it would be the obvious place to ask...

I want to replace the DIFF oil in my 1995 E34 525I (no LSD). Can you recommend some easily attainable oil that I can pop in there Bluebiggrin
Is it worth getting the OEM oil from BMW?

1987 E30 320I, 1995 E34 525I, 1998 E38 740I

Sorry, my supplier was battling to find an M5 diff cover, it seams I can't get one, they are hen's teeth. Just PM me your banking details so I can transfer your money back.

I think a 5mm steel plate cut to the right shape bolted to those large two bolts on the e34 diff cover will suffice.

Just go to any Autozone/Midas and get Castrol 75w-90 gear oil.

RE: BMW Differential Tutorial, with pics.
Hi, new to forum but got a diff problem I guess.

When I slightly move the end of my propshaft clockwise, my diff "clunks" and I got play here obviously as I can move propshaft while car on handbrake.

Any guesses what this can be?

I heard also that in europe the 520i had LSD as an option, that must be the small casing then and that E30 boxes fit as well if changing casings.

If I want to change to LSD what is best ratio for a 520i?

This is what I found sofar on 520i's, don't know whats true about these ratio's:

4.45 12v manual 5
3.91 24v manual 5

There's a chart of which diffs came in which E34's on Bruno's site. www.bmwe34.net

he M20's had 4.1,
the M50
2.5 had 3.23
2.0 had 3.64

The 3.46 LSD is from an e34 520

RE: BMW Differential Tutorial, with pics.
Well, if you want a little more acceleration you can go from your 3.64 to 3.91 ratio. I can build you a 3.91:1 LSD for your E34 for R1800, shoot me a PM.

Still waiting for my spare turbo to arrive so I can see what needs to be done to get it fitted as its a bit bigger & space is at a premium.

But I decided to make a project of it & somme do some TLC all in one

Will probably only run early next year again.
