i bought two wheel bearings because i went and got my truck aligned and they said the driver side wheel bearing was bad. i figured since i was going to replace one might as well replace both. well i jacked the truck up replaced the upper ball joint and there is no play in the hub at all i tried grabbing the bottom and top and pulling in and out...no moovy! i have almost 260k miles on my truck and the wheelbearings have never been replaced. i dont drive easy either. im really confused!
