Inspection and Verification
Certain axle and driveline symptoms are also common to the engine (6007), transmission, wheel bearings, tires, and other parts of the vehicle. For this reason, be sure that the cause of the trouble is in the axle before disassembling, adjusting or repairing the axle. For additional information, refer to NOISE, VIBRATION & HARSHNESS .
Certain driveshaft vibration symptoms are common to the front accessory drive (FEAD), the engine, transmission or tires. Be sure the cause is the driveshaft before repairing or installing a new driveshaft. For additional information, refer to NOISE, VIBRATION & HARSHNESS .
Certain symptoms may be caused by Traction-Lok® differentials (4026). Check the vehicle certification label and axle identification tag to determine the type of differential. For additional information, refer to IDENTIFICATION CODES .
