On-Vehicle Service
PROPELLER SHAFT VIBRATION

CAUTION: If vibration is present at high speed, check mounting between propeller shaft and companion flange.

If vibration is present at high speed, check propeller shaft runout first.





1. Measure propeller shaft runout at several points by rotating final drive companion flange with your hands.
Propeller shaft runout limit: 0.6 mm (0.024 inch) or less
2. If runout still exceeds specifications, disconnect propeller shaft at final drive companion flange: then rotate companion flange 90, 180, 270 degrees and reconnect propeller shaft.
3. Check runout again. If runout still exceeds specifications, replace propeller shaft assembly.
4. Perform driving test to check.
5. If the runout exceeds the service limit, do the following:
^ Remove the propeller shaft from the final drive companion flange.
^ Turn the propeller shaft 60, 120, 180, 240, 300 degrees and reinstall the propeller shaft to the companion flange, then measure the runout again.
^ If the runout still exceeds the service limit, replace the propeller shaft assembly.
^ Check the vibration by driving the vehicle.

APPEARANCE AND NOISE INSPECTION
^ Inspect propeller shaft tube surface for dents or cracks. If damaged, replace propeller shaft assembly.
^ If center bearing is noisy or damaged, replace propeller shaft assembly.
