Certain axle noise or vibration symptoms are also common to the engine (6007), transmission (7003), wheel bearings, tires, and other parts of the vehicle. For this reason, be sure that the cause of the concern is in the axle before disassembling, adjusting or repairing the axle. For additional information, refer to BASIC TROUBLE SHOOTING .
Certain driveshaft vibration symptoms are common to the front engine accessory drive (FEAD), the engine, transmission or tires. Be sure the cause of the concern is the driveshaft before repairing or installing a new driveshaft.
