Trailblazer, I was also having the problem with the front dogbones being chewed up. did you ever find a solution? I have read to shorten the turning radius helps. I do not like this option, I am trying to figure out a new option, Has anyone figured out what the cause is? is it binding up because the slot in the knuckle arm is to small, and would opening the slot help? or is it the drive cup (the part the dogbone ball rests in) maybe would a bit more angle help to keep the binding down?
