Jeep Grand Cherokee Thumping Sound Q. Vincent, I just recently purchased a 1997 Jeep Grand Cherokee Laredo and have a "thumping noise" coming from the tires. Very light but annoying thumping. The Jeep has 144,000 miles and 4.0 liter engine. The used car dealer that I purchased the Jeep from replaced all the rotors and brake pads on all four wheels, but the noise still continues. The tires are almost brand new and are "P235/75R15" XC LT4 Michelins. Thank you, Gary

A. The first thing I would do is rotate and balance the tires. This sound is usually indicative of a bad tire, probably a slipped belt. If the noise goes away you have found the problem.
