Propeller Shaft Vibration

WARNING: This page is about a different car, the 2013 Nissan Armada. However, it is still accessible from the selected car via links, so may be relevant.

If a vibration is present at high speed, inspect the propeller shaft runout first.

Measure the runout of the propeller shaft tube at several points by rotating the final drive companion flange with your hands.

If the runout exceeds specifications, disconnect the propeller shaft at the final drive companion flange; then rotate the companion flange 90°, 180° and 270° and reconnect the propeller shaft.
Check the runout again. If the runout still exceeds specifications, replace the propeller shaft assembly.
After installation, check for vibration by driving vehicle.
