Re: 2012 800s pinion fail, new diff ?
The shim you are talking about, is it about the size of a 3/8 flat washer, stainless? If it is it came out off of the bolt that is next to the crank position sensor, between the trans/diff bracket and the adapter tube housing.
The Loctite 272 or Permatex 27200 should be used, it tolerates oil, 271 or 277 do not like oil. The new nut can be staked with a center punch at the top after if is torqued. The pinion shaft threads and nut should be oil free for the threadlok to work properly.
