OEM Specs for Diff Rebuild

[gte869h]

Looking for specs on the e9x M3 differential which I’m rebuilding with new bearings, seals, and a Wavetrac unit.

But I can’t find any specs for this generation diff. I’ve built a non-M e46 LSD with a 4-clutch pack turner motorsports unit and had a way easier time finding numbers. However, this generation of diff uses bearings that aren’t taper roller so I expect spec to change.

Could someone post specs for:
1) Pinion bearing preload
2) Ring gear bolt torque
3) Ring gear backlash
4) Carrier side bearing preload

Please don’t hijack this thread with your preference on the LSD carrier.

Thanks a bunch!

What were the part #s for the Outer pinion bearing and race? I have the part #s for the rest of the diff.

Thanks

When I rebuilt mine, I just bought a complete rebuild kit from diffsonline.
