TROUBLESHOOTING

The following conditions may indicate damaged shaft drive components:
A Symptoms
1. A pronounced hesitation or jerky movement
during acceleration, deceleration, or sustained
speeds (not to be confused with engine surging
or transmission related movements).
2. A rolling "rumble" noticeable at low speeds, a
high-pitched whine, or a "clunk" from a shaft
drive component or vicinity of the shaft drive.
3. The shaft drive is locked up or no power is
transmitted from the engine to the rear wheel.
NOTE:
Causes A, B and C may be extremely difficult to diagnose. The symptoms are quite subtle and difficult
to distinguish from normal operating noises. If there is reason to believe these components are damaged,
remove them for individual inspection.
