I have a 1995 Yamaha Big Bear 350 All time 4×4. Recently while riding, I lost my rear drive. I never heard any noise at all and when picked up, the rear spins smoothly with no noises out of ordinary. I’m trying to take apart rear differential but I’m having problems getting axle ring nuts off. This seems like a dumb question to be but what direction do they spin to come off? While standing behind it, do I turn them up, towards front of bike, or down, towards rear of bike? Please help, I need to figure out what may be needed to fix problem!!!
