Axle Noise

AXLE NOISE

Note:
^ Before disassembling the axle to diagnose and correct gear noise, eliminate the tires, exhaust, trim items, roof racks, axle shafts and wheel bearings as possible causes.

The noises described as follows usually have specific causes that can be diagnosed by observation as the unit is disassembled. The initial clues are the type of noise heard during the road test.
Howling or whining of the ring gear and pinion is due to an improper gear pattern, gear damage or improper bearing preload.
