On my 1993 D250 I put those leveling pucks to bring up the front end. After doing the kit I readjusted the camber back to vertically level. I bought new tires and only have driven 6k miles on the and the inside of the tire is already gone. I've asked around and people are saying lower ball joints but I replaced those about 15k miles ago. I've looked at the whole front end but I don't see anything bent. Any suggestions, comments, gripes what have you are greatly appreciated.
