So I just had both upper ball joints replaced after the front driver side one snapped in two and almost landed me into a car in the next lane and a month later I'm having some problems with negative camber on the same side. Now I'm just assuming it's negative camber (with the inner tread taking a beating) and there is some squealing coming from that same wheel which could also be associated with it. My question was; how did it happen and how do i fix it. I desperately need to replace my tires (which are now almost slicks) and I have to do it before I go to the tire shop lest I spend a couple hundred more to have them fix it for me. I'll post some pictures as soon as my camera is done charging so someone with a little more expertise can tell me if it is camber or if there's something else goin' on down there.
