i have a 92 limited with a 4.5 inch rough country lift with stock uppers and their fixed lowers. i was running 245/75/16 goodyear mtr. the problem is they only lasted a couple thousand miles. i had to rotate them every two weeks. i know my allignment isnt perfect but its pretty close. ive ive searched offset ball joints and still dont know if that is the answer. it sounds like they should only be nessecery if something is bent. my axel isnt bent but my caster/camber is visualy off. any sort of help would be great.
