I'm looking to purchase a used Ranger that I think is a pretty good deal, but it is a 2010 800 with around 250 hours. The only things replaced so far are tires, oil and battery. I know there are a lot of wear parts on these, but is there really a way to tell what needs replaced without taking everything apart? Are there tests you can do for bearings, ball joints, etc? Sorry for sounding naive, this is my first atv-utv purchase. Does anybody know of any common problems for this year?
