Diagnostic Information and
Procedures
Vibration Diagnosis
The techniques and procedures for correcting the
following types of vibrations are including in the road
testing diagnosis:
• Tire and wheel shake
• Steering/suspension shimmy and shake
• Launch shudder
• Exhaust moan
• Engine firing frequency
A Process of Elimination
A few basic concepts must be understood before
attempting to diagnose a vibration. As in any
diagnostic process, information must be gathered and
deciphered, and a correction made based on the
results. Road testing and inspecting the vehicle in a
manner which systematically eliminates different
components, in turn supplements the information
received from the customer concerning the complaint.
Concentrating efforts on the areas that have not
been eliminated will make repairs faster and more
effective.
