TROUBLESHOOTING

The following conditions may indicate damaged shaft drive components:
A Symptoms
1. A pronounced hesitation or jerky movement
during acceleration, deceleration, or sus-
tained speeds. (not to be confused with engine
surging or transmissionrelated
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 dam-
aged, remove them for individual inspection.
