NOISE
Check the propeller shaft tube surface for dents or cracks. If damaged, replace propeller shaft assembly.
VIBRATION
If vibration is present at high speed, inspect propeller shaft runout
first.
1.
With a dial indicator, 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 90,
180, 270 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.
