I've gone through 3 sets of bushings 1 factory and 2 poly ones and have also replaced the rack I don't even want to get into how many inner and outer tie rods I've gone through. I have a 3" spacer kit and I'm dropping it to 2.5" and see what gives. But I just want mine to hold together for one last season then I'm doing the SAS. I'm re-doing the drive train this year.
I'm gonna suggest checking out the brackets that were installed for this kit and see if anything is bent or not mounted correctly. Just a thought.
