I disassembled the Input shaft that comes from engine from the diff flange and noticed there is a blue gasket in between both. It was damaged and I am not sure if it needs to be replaced as I didn't see it on this DIY.

Hey guys. If you swap input flanges from one diff to another. How do u know where to put one in and mark it, etc?
Secondly, if I opt not to do that, where might I find JUST the I put flange for purchase.
I can't seem to find a part # on realoem. Any idea? I bought a diff and FedEx managed to damage/dent the input flange and the back cover.

Excellent write up. Did mine today and changed the fluid.

No more leaks and no more grinding Diff noise. I strongly suggest anyone doing this, to go ahead and change their Guibo as well and also purchase a new Diff output shaft locknut plate as they will be destroyed in most cases.

I need to replace the Guibo and the Nutlock P/N: 33121205138

And if I remember right, requires you to measure the torque required to turn the diff and rear wheels before disassembly (although, I bet an estimate is close enough).

Search bimmerforums or e46fanatics and see if you can find it.
Where is this crush sleeve? I didn't see it in the images shown?

Back from the dead, but anyone knows the proper torque for the input flange nut?
