Correction

DEFINITION: When the vehicle is accelerating at low speed, a shudder occurs.

Propeller shaft rev limiter/snubber contacting the driveline tube - manual transmission applications only

A rev limiter/snubber that is contacting the driveline tube may create a moaning type noise and/or vibration that is felt through the shift lever. Slight noise and vibration is to be considered normal during an over-speed condition but should not be present when the over-speed condition has ceased.

Replace components, as required.

Propeller shaft out-of-balance condition

A propeller shaft out-of-balance condition may create a vibration and be caused by:

    • Worn rev limiter/snubber - manual transmission applications only
    • Bent propeller shaft
    • Loose or missing parts
    • Worn or broken coupling

Replace components, as necessary.
