Removal Procedure

Important: In order to remove any frame insulator, loosen the adjacent frame insulators to permit the frame to separate from the body. Do not break the fan shroud or damage the frame attachments, such as steering hoses and brake pipes during the replacement of body mounts.

When installing a body mount, ensure the lower insulator is seated into the frame. The lower insulator should not be loose. The spacer and the corresponding upper insulator is pressed into the lower insulator thus squeezing the frame. The bolt is then inserted through the mount, capturing the lower retainer. The body mount components prevent contact of the frame to the body.

Do not over tighten the body mount. Over tightening may collapse a spacer or strip a bolt. When the frame insulator bolts are removed, always discard the bolts and replace with new bolts.

When clamping by the mount, ensure the surfaces are clean and dry. If the frame insulator bolt does not screw in smoothly, run a tap through the frame crossmember nut in the body in order to remove foreign material. Ensure the tap does not punch through the underbody.

Whenever the body is moved in relation to the frame, disconnect the intermediate shaft from the rack and pinion steering gear and stub shaft.
