Hi, just joined here. I have a 2005 700 EFI sportsman and a few months back i got it stuck in the river mud. In the process of getting it unstuck i managed to break BOTH front cv shafts, and i think i broke something inside the front diff. I changed the cv shafts and I first noticed something was wrong with the diff when i went to back it off my ramps in 2 wheel drive the front wheels didnt wanna freewheel they were binding and locking up on the ramp. When i jack it up and try spinning the wheels one time in 2 wheel drive it will spin all 4 wheels, then the next time only the backs. Other times it will only spin 3 wheels. Im at a loss, i am mechanically inclined as i work on cars and trucks for a living, but i don't know much about fixing ATV's. How hard is it to pull the diff out, and what would i be looking for when i get in there? Thanks in advance!
