Rear Propeller Shaft: Inspection: Vibration

WARNING: This page is about a different car, the 2011 Infiniti G37. However, it is still accessible from the selected car via links, so may be relevant.

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

With a dial indicator, measure propeller shaft runout at runout measuring points by rotating final drive companion flange with hands.
Propeller shaft runout: Refer to "PROPELLER SHAFT RUNOUT ".

If runout still exceeds specifications, separate propeller shaft at final drive companion flange or transfer companion flange; then change the phase between companion flange and propeller shaft by the one bolt hole at a time and install propeller shaft.
If runout is more than the limit value, remove and check propeller shaft.
Check the vibration by driving vehicle.
