Hi everyone, new to the forum. Been looking and looking for some answers for a few weeks, and no luck. I have a 10 mp 700h1. I recently had to rebuild the rear diff as the ring gear teeth started chipping away. The housing is still good. Bought new ring and pinion gears and everything else. I have the book for it and reassembled the diff per book. Book said to use the same shims if re-using housing, which I am. I get the whole thing back together and in the bike. Get everything else together and start it up and put it in gear and it goes no where. Driveshaft spins but tires wont. I can put it in 4wd and it will move all 4 wheels. If I drive around in 4wd and shift back to 2wd it will keep going till I stop. If I take off again in 2wd wont move. All this happens in reverse and forward. Any advice here? Local arctic cat shop isnt much help. They replaced pinion gear for me 3 weeks ago and now wont answer my calls.
