1998 Jeep Grand Cherokee Laredo 6 Cyl 4.0L - Transmissions & Drivetrains
why there is a grinding noise in my rear differential
i noticed a slight grinding noise as i was driving. as time has gone on it has gotten worse. it sounds like metal rubbing against metal and replacing the rear rotors, calipers, brakes and bearings did not stop the issue. when the jeep is jacked up and rear tires are off the ground you cannot hear it. this happens all the time regardless of temperature or terrain. there are also no warning lights. the jeep is two wheel drive and has 170000 miles on it. thanks for your help.
