I have a 22 Wagoneer series III with air ride. I use to have a repair shop and did alot of vibration issues. I am having the same issue with vibration as others.....however I had the alignment checked at 2500 miles and was shocked with the spec's when I picked it up. Thought either Jeep made a mistake or the air ride adjustments at different speed would adjust the toe in condition. With the adjustment that was just made to a positive .20 on each side I feel unless there is something I don't know, it will definitely wear tires and create a vibration at highway speeds. I have contacted Wagoneer engineers to see if this spec is right?
