I am new to the forum so I am sorry if this already has a thread started... I have a 2010 RZR S 800 that has a aftermarkert rear end housing and stock gears according to previous owner... I was going along the other day no noise or anything and the rear end locked up let up on the excelerator and wheels started to turn again, I then proceeded slowly up along side our field and across the yard which wheels were turning and could hear noise from rear when again rear end locked for just few seconds and released..... When put in reverse it makes bad popping noise. I have taken the plug out of rear diff and can see what looks like 3 chipped teeth on the large gear. There is no damage to the case.

I have found a complete rear diff out of a 2013 with 1 mile on it.. Will it fit my 2010? Both are 800 RZR S.

Or what is best thing to do here as the case is not cracked or broke?

Thanks for any info in advance! I just want to ride again been down to long...

I just talked to the previous owner and he says it is all stock... Internals and the case.

What are some options?
