IF YOU CONFIRM

Diagnose by evaluating the u-joint with the propeller shaft removed. If the u-joint axial play or flex effort exceed the specifications in the Electronic Service Manual (ESM), or if a "ratchety" feel is exhibited during rotation, the u-joint (journal/journal bearings) should be replaced.

ACTION

Replace the u-joint (journal/journal bearings).

^ Refer to the applicable ESM for removal and installation instructions.

NOTE:
Do not replace the entire propeller shaft assembly if u-joint (journal/journal bearings) replacement can resolve the incident, should it occur.
