REAR PROPELLER SHAFT : Periodic Maintenance Operation: Vibration

WARNING: This page is about a different variant/trim than selected.

If vibration is present at high speed, adjust the propeller shaft phase first.

  1. Check the propeller shaft for bend and damage. If damaged, replace propeller shaft assembly.
  2. If the alignment mark SYMBOL of the propeller shaft SYMBOL and the alignment mark SYMBOL of the companion flanges on the final drive are not on an axis, re-install these parts to a closer position as possible.

  3. Perform a cruise test drive to check the propeller shaft for runout after installation. If vibration still occurs, separate propeller shaft at final drive companion flange; then change the phase between companion flange and propeller shaft by the one bolt hole at a time and install propeller shaft.
  4. If vibration is still detected, measure propeller shaft runout after removing it. Refer to REAR PROPELLER SHAFT : Inspection  (2WD).
