Any good news? I had a heck of a time getting an alignment shop to work on my 6.4L Ford, instead of just looking at the alignment. So, I asked for before/after computer printouts. I even bought a 0 degree bushing and handed it to them in case we needed to recalc the correct bushing. I was a pain in the butt. No doubt about it. I was nice but I wanted the problem fixed. I got a good alignment done.
You did not say what the wear pattern was. Just general tire wear? I had a camber issue on the driver side and it was obvious in the tire wear. Lots of shops have machines telling them they are “in spec” and you need to look at the printouts for actual measurements.
Best of luck. -d
