I have a '92 GT that began wearing the front tires unevenly a few months ago. I'm running the stock size tire/wheel combo, but there is too much negative caster,and 3 different tire dealers have been unable to fix the problem or tell me why it occurred.My car has theoriginalstock springs, but I have replaced the struts (KYB non-adjustable)9,000 miles ago, along with the steering rack, and tie rod ends. Last week Ir/r theball joints and it still has negative camber. Any suggestions or insights? I'm thinking the struts are wore out, but they should'nt be yet.
Thanks.

 

Replace the cast camber plates with adjustables. That should allow you to re-align the suspension to correct the problem. However, you still have an alignment issue that needs to be determined.
