Recently noticed that my front tires are cupping HORRIBLY. I am running 33x12.50x15 BFG km3's. The rear tires are all evenly wearing and look much newer than the front ones do. The set has probably 9-10k miles on them. They were originally on my TJ and I rotated them at the 6k mile mark. At that point there was no irregular tire wear. Since then I got rid of the TJ and purchased an LJ and swapped all the parts. Since they have been on the LJ, they have started to wear badly on the front and started to howl and cup. I did align the tires when I first put them on. I can tell now that it is not aligned anymore because the jeep will pull to the right and the steering wheel is not center. Also sometimes when turning the steering wheel I hear a loud pop noise. Nothing is rubbing so I'm not sure what the noise is. Maybe a bad track bar bushing or ball joint? I am also on stock control arms right now so could it be improper caster?(2.5 in suspension lift). I needed a beefier tie rod anyways so I bought the ZJ tie rod and am going to re-align and check all the components when it comes but I was wondering what things specifically I should focus on. I will also probably rotate the tires so they don't cup any further but I really don't want the current rear tires to move to the front and start cupping as well.
