Certain axle and driveline symptoms are also common to the engine, transmission, wheel bearings, tires and other parts of the vehicle. For this
reason, be sure that the cause of the trouble is in the driveline before disassembling, adjusting or repairing the driveline. Refer to Vehicle/Testing
and Inspection.
