I just replaced the ball joints for the 3rd time this weeked. Now I expect them to wear because im on 33s and I wheel it. But the thing is its only been on the passenger side. I have never replaed the driver side, they might be loose and could use replacing but they have no play, unlike the passenger side that had seperation at the upper and lower when prying up on the tire. Nice thing is that they are moog and they have a lifetime warrenty so I just keep getting new ones for free. But my question is any one have an idea why I keep blowing thru just passenger sides?
