Check the propeller shaft tube surface for dents or cracks. If damaged, replace propeller shaft assembly.

●

PROPELLER SHAFT VIBRATION

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

1.

Measure propeller shaft runout at runout measuring points by
rotating final drive companion flange with hands.

2.

If runout still exceeds specifications, separate propeller shaft at
final drive companion flange; then rotate companion flange 60,
120, 180, 240, 300 degrees and install propeller shaft.

3.

Check runout again. If runout still exceeds specifications,
replace propeller shaft assembly.

4.

Check the vibration by driving vehicle.
