I have a 88 xj (that is at stock height and 225/75/15 tires) that when I hit a bump on the thruway it starts shaking real bad. It only happens when I hit the pothole around 55 MPH. I can drive down the thruway at this speed and everything is ok until I hit a pothole. It goes away and soon as I slow down to under 55 mph. I changed the front tires to 215/75/15 tires and the problem is still there. Any help is appericated.
Thanks, ED
