I'll try to keep this short. Traded fro a 2006 sportsman 800. AWD worked well on wet grass and slick mud. First time a tried to climb out of the mud pit the front right wheel stopped turning and started clicking when it hit hard dirt trying to pull the bike up the bank. Figured it was the diff basket, so I ordered it with new armature. When parts came in I tore the diff down and found zero problems inside. Good rollers, basket, armature, bearings. etc. Replaced the basket and springs anyway. Put it back together and had same problem. Figured the front right axle splines must be worn letting the hub slip. Replace with new alxe. Same problem exits. I have invested over $350 in the frontend and solved nothing. Has anyone ever had to replace the output hubs in the front diff ? 3000 miles on the quad. The new hubs are $450 if I replace both.
