i was checkin under my old bronco and my rear driveshaft yoke had a fair amount of play in it connecting to the rear differential. i dont hear or feel anything going down the road. a fellow told me it was a bearing in there that could be causing this. said it could slice up my gears...how much would it cost to have this replaced since i have no tools or experience to take the rear end apart...ill call around tomorrow but no place is open right now and i just got paid. or should i just swap in a rebuilt 9". i dont plan on keeping the truck very long though.
