Grizzly axle, rear diff, bearing.

New here.. I have a clunking noise coming from right rear wheel. When I’m turning out decelerating it happens the most I installed a new axle and bearing. I bought the machine used and it had a broken axle so I thought no big deal.. Wrong!.:evil: Anyway I pulled the plug on the diff nice and clean no metal or water.. What do you guys think I’m hoping it’s not the diff but maybe a scarred rebuilt cv joint. Thanks Rob
