Vibration from the front of the car between 52 and 57 MPH. I have replaced with new parts the: Hub assemblies, differential bearings and seals, axle joints, steering damper, track bar, rotors, brake pads, and tires.
Such a dependable car that will keep on going even with minor problems. Mud, snow, and water are no match for this impressive vehicle.
Rear air shocks are a good upgrade to get rid of that leaf spring sag and adjust for different payloads.
I am curious, you say your Jeep Cherokee is 2001, but I believe they stopped making those in 2000. I have a Cherokee Sport 2000, straight in line 6 cylinder, 4.0 liter engine, 4wd, but that was the last year they were made, then they went to the Liberty. Is yours a 2000 model, that you bought in 2001?
I'm pretty sure that 2001 was the last year for the Jeep Cherokee.
