ISSUE:

A cab/body bounce at highway speeds may be felt on some vehicles. This may be caused by road input (e.g., segmented concrete roads) that causes the cab/body to bounce rhythmically fore & aft at highway speeds.

ACTION:

Install a rear bumper damper assembly. The damper assembly should reduce the possibility of vibration. Refer to the following Service Procedure for details.
