Default Re: Adjusting Diff backlash

I have opened 2 of these LSD's.

I would personally forget about the shimming of orbital gears. The orbital gears have a concave shim on the back of them already that makes contact with the housing and the back side of the gear itself. I noticed them same amount of wear in both LSD components and while its not bad , its still a fair amount when compared to how the ring gear and pinion wear.

The is some grooves in the gear contact between the bevel and planet gear. I wouldnt attempt to shim is because I think you will increase the wear rate and friction between them. BMW have bulletins from when the car was new to say that a noise in the driveline is normal and not to be "fixed" tampered with in other words.

Shim can be seen on the back of the planet gear here
