Newbie here,
Just bought a used 2017 570 xmr with 215 miles on it and noticed a harsh noise coming from rear diff, Upon further inspect, found excessive movement in axle area of differential. Removed differential and split cases and found case was packed with gunk????? Cleaned and found Ring gear is pitted and has chips missing of the outer edge, inspected pinion gear and found some pits and pinion is sharp indicating incorrect shimming. (Forgive my typing, I'm a Nissan dealer line tech) Anyways, Question is, should I just slap some new bearings and seal in it and save up money for a new rear diff or just leave it on the stand? This is my first atv BUT I'm no stranger to 4wd's.
Thanks in advance....:aniwheeler6:
