Vibration Analysis - Driveline

Test Description

The numbers below refer to the step numbers in the diagnostic table.
8. In most cases, the vibration can be reproduced in the stall, but it is either not as bad or a lot worse than experienced on the road. This is normal. First-order driveline vibrations may be caused the imbalance of a component. The In-Stall test will help determine which component needs to be repaired or replaced.
9. If the vehicle has a vibration that is equal to first-order driveline rotation, and it is not present when testing the vehicle in the stall, then it is possible that the vibration is being generated by internal rear axle components. This may also be true if the vibration was correctable in the stall but returned when the vehicle was driven on the road.
