Drive flange endfloat

[billjam]

"While I'm in there" I decided to replace my notchy first gear synchro.
As I was cleaning up the gearbox ahead of dismantling, I noticed that the RHS drive flange moved in and out of the diff slightly.
I checked the LHS and it doesn't have any axial endfloat at all, yet the RHS has 0.8mm.
Yes, its retaining bolt was tight.

I can't find any mention of endfloat in the factory manuals and looking at the exploded views of the LSD I don't see any means of shimming or adjusting this endfloat.
I have removed the diff to replace seals and everything looks OK on the inside - not that you can see much inside the LSD centre.

Car is an '86 930 with LSD. Is it normal to have some endfloat here?
It just seems odd to me and I don't recall having this amount of endfloat on any of my other cars. Maybe its a LSD thing?

The threaded button that is normally a press-fit into the side gear is no longer a press-fit. While the buttons are somewhat held captive by the cross shafts, it's still a good idea to replace them the next time you service your LSD.
