my Yamaha 350 big bear, 1998 2 wheel drive quad developed some problems in the rear differential. All the bearings were trashed as well as the pinion gear. I have found a 2002 kodiak 400 , 2 wheel drive that is being parted out for $100. Would this rear end or any of its components fit my quad? new bearings $50;and pinion gear will cost @ $180. Any advice would be appreciated.
