Frame Insulators Description





Improper frame insulator (3,4) installations may result in the following problems:

* Popping noise
* Structure shake
* Road noise
* Squeaks
* Snapping noise


The problems listed above may sometimes be caused by the installation of a wrong part or an improperly tightened insulator. Squeaks may be caused by an improperly located insulator rubbing on the frame rail.


If a problem is diagnosed as an insulator problem, perform either of the following procedures:

* A color code check of the insulators
* A body bolt torque check


Use either procedure to determine the correct usage of the insulator. If the wrong insulator is used, replace the insulator with the correct part.
