320is Diff Rebuild (Pic heavy)

[e21Terry]

That would be the easiest route. I would suggest measuring the backlash and checking the contact pattern and taking a picture on the 3.45 before doing the lsd carrier swap. It is possible that you may have to adjust the side shims with the different carrier and doing the suggested checks will allow you to get things back as they should be.

I just like saying "Mmmm Klingelnberg flavinn" in Prof. Frink's voice.



I suppose this one would be more beneficial if it were legible.

Thanks for the better pictures, I've been posting from my phone as of late so my selection is somewhat limited

Nice work...Question when I go e30 diff this year in my e21, can you add rebuild this one for me. I saw an OBDX part on ebay for the e30 diff, and I would like you to install that, it makes it a true LSD....

^ what is a OBDX and why would you say that the factory's 25% LSD is not a true 'limited slip differential'?

BRAND NEW ~ BMW Quaife ATB Helical LSD Differentials

BMW QUAIFE ATB HELICAL LSD DIFFERENTIALS
eBay item number:
290992258157

Seller assumes all responsibility for this listing.
BRAND NEW ~ NEVER INSTALLED
Fits the following models:
735I - 633CSI - 535I E28 - 535I E34 - 325I E36 - 525I E28 - 525I E34 - M3 E30 - M3 E26

Unlike a conventional plate-style limited slip differential, the BMW Quaife ATB Helical LSD differential relies on gears rather than clutch plates for its operation. That means it is much smoother in operation.
The BMW Quaife ATB Helical LSD differential never locks harshly with a set preload of wheel slip across the driven axle, like a conventional LSD. Rather, the BMW Quaife ATB Helical LSD differential automatically biases the torque away from the spinning wheel across the axle, to a constantly varying degree, and never locks.
The BMW Quaife ATB Helical LSD differential has many benefits over a standard open differential, including: maximizing traction and minimizing wheel spin; eliminating torque steer and snatching in front wheel drive cars compared to conventional LSD units; and a maintenance-free design which retains the standard oil lubrication.
The BMW Quaife ATB Helical LSD differential is proven in circuit racing, drag racing, rallying and road use. It is produced from Corus Steel Billets, is CAD designed and CNC machined, then inspected to ISO 9001 standards.
The BMW Quaife ATB Helical LSD differential is second to none! Accept no imitations!
BMW Quaife ATB Helical LSD differentails are used by Ford, General Motors & Daimler-Chrysler as original equipment.

Clutches, locker, quaife, etc.

All variants of limited slip differentials.
Distinguishing characteristics include: design, application and most importantly - price point.

exactly, by design doesn't make it more of a 'true' LSD.
