Driveshaft Vibration Diagnosis

Driveshaft Vibration Diagnosis

1. NOTE: When carrying out the following procedure steps on four-wheel drive vehicles, raise and support the vehicle so that all four wheels do not touch the ground.

Road test the vehicle to determine the critical vibration points. Note the road speed, the engine RPM, and the shift lever positions at which the vibration occurs.
2. Stop the vehicle, place the transmission lever in NEUTRAL and run the engine through the critical speed ranges determined in Step 1.
3. If no vibration is felt, balance the driveshaft.
