To add to my vibration issues with my 01 Cherokee, I also have a wobble that can be felt in the steering wheel and front seat at 55 mph. Its not noticeable before that speed and goes away around 60 mph.So far Ive had the tires balanced, then road force balanced, tried new rims and even another set of rims with different tires. The problem remains. I had the shop that balanced the tires check the front end but they said it was good. Obviously it not rims or tires so whats next on the list?
