Does anyone have the 2004, 660 repair manual? My rhino rear end or transmission is grinding and I need to take it apart. Last year I had someone repair frame cracks and the drive line due to the rear end bolts coming loose. It seems to be happening again. The bolts are tight but maybe something else is the cause. It started to make noise when coming down hills with no gas pressed. Ended up shortly after with a clicking/grinding noise (bad) on deceleration down hill. I got it driven into trailer without the noise (forward/reverse under power no noise). I'm going to try and fix it myself this time so any help would be appreciated.
