Body / Frame Mount Bushing: Service and Repair

Removal Procedure
Important: 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.
1. Raise and suitably support the vehicle. Refer to Vehicle Lifting.
2. Remove the frame.
3. Remove the upper and lower insulators from the rear of the frame as a set.
