1997 ranger automatic, ok the truck has the wheels balanced, and the tires are fairly new, it has a lot of vibration at about 60-65 then goes away at 70? i believe it needs new u joints because it sometimes clunks into gear, im thinking it might need the wheels rebalanced? or the driveline balanced? but how do you go abour balancing a driveline and how much would this be about to have the u joints replaced and driveline balanced?
