99WJ. It's driving me nuts! The back driver's side axle emits a constant "squeak squeak squeak" sound as it rolls along. It is speed sensitive (occurs more often as speed increases) and does so if the brakes are applied or not applied. At first I thought it was the rear brakes squeaking away, so I did the usual stuff; anti-squeal on the back of the pads, made sure everything was tight, checked the rotors to see if they were warped. None of this has affected this squeak. I completely ruled out brake squeak today as I drove down the side of Lowes and listened to the squeaker and applied the brake in a moderate fashion. It squeaked till it came to a complete stop, the same squeak squeak squeak it has been doing.
There are no signs of any metal to metal contact at all on anything that rotates back there. I looked at the backing plate (dust shield), the e-brake shoes, inside the rotor where the e-brake applies, behind the axle shaft hub, everywhere I could think of to look and even checked out the studs in the axle to make sure all of them were tight. I have tried putting the WJ in the air and listening while it was in drive, but unless the rear has weight on the tires there is no squeaking at all. I rotated the tires hoping it was the tire making the noise but the squeak didn't move to the passenger side front. Unless I have a family of mice going for a joy ride in my rear tire then I am out of ideas. Anyone else able to point me in a new direction?
99 WJ Laredo - Mine once again!
