Drive/Propeller Shaft: Testing and Inspection
Propeller Shaft Imbalance
If propeller shaft imbalance is suspected, it can be verified with the following procedure.
NOTE: Removing and re-indexing the propeller shaft 120° may eliminate some vibrations.
Clean all the foreign material from the propeller shaft and the coupler flanges (mud, undercoating, etc.).
Inspect the propeller shaft for missing balance weights, broken welds, and bent areas. If the propeller shaft is found with any of these conditions, the
shaft and couplers must be replaced as an assembly.
Ensure the coupling flanges are not worn, are properly, installed, and correctly aligned with the shaft.
Check the coupling flange bolts torque.
Check propeller shaft angle.
1. Start the engine and check for vibration. Accelerate through all RPM ranges. If there is a vibration at a certain RPM, remove the propeller shaft
and reindex 120°. Repeat the vibration test.
2. If there is no change in amount of vibration, replace the propeller shaft and couplers as an assembly. Refer to propeller shaft replacement.
3. If the vibration occurs at a certain vehicle speed, the propeller shaft is not the cause.
