FRONT PROPELLER SHAFTPFP:37200
On-Vehicle ServiceADS000KL
PROPELLER SHAFT VIBRATION
If vibration is present at high speed, inspect propeller shaft runout first.
1. Measure propeller shaft runout at several points by rotating final
drive companion flange with your hands.
2. If runout still exceeds specifications, disconnect propeller shaft
at the final drive companion flange; then rotate companion
flange 90, 180, 270 degrees and reconnect propeller shaft.
3. Check runout again. If runout still exceeds specifications,
replace propeller shaft assembly.
4. Check the vibration by driving the vehicle.
APPEARANCE CHECKING

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