I used to run a repair shop, and I have dealt with vibration issues many times. I'm now having vibration problems on my wife's 22 Wagoneer series III, and I had the alignment checked at 2,500 miles and was surprised by the specs when I got it back. I thought either Jeep made a mistake or the air ride adjusts the toe at different speeds. They set the toe to positive .20 on each side, and I think this will cause tire wear and vibrations at highway speeds. I’ve contacted Wagoneer engineers to confirm if these specs are correct. What do you all think?
