Front Floor Carpet or Rubber Floor Covering Poor Fit, Loose or Bulging (Install Floor Insulator/Deadener)

Some customers may comment on the way the front floor carpet or rubber floor covering fits on the floor tunnel as shown in the illustration. Others may comment that the floor covering is loose, bulging or just fits poorly on the passenger side.

This condition may be caused by a lack of padding under the front floor carpet or rubber floor covering.

Install floor deadener to the top of the floor tunnel using the steps below.

Important: The deadener or insulator is not currently available from GMSPO. It will be necessary to purchase the material locally from an automotive trim shop, until the insulator becomes available.

1. Remove the carpet or rubber floor covering away from the front floor tunnel. Refer to Floor Panel Carpet Replacement (Regular Cab) in SI.

Important: For vehicles equipped with a manual 4 x 4 shifter, the shifter knob and trim plate will need to be removed. Refer to Transfer Case Control Lever Replacement in SI.

Tip
The instrument panel (IP) support bracket will need to be removed by prying apart the two trim panels and removing the bolts.




2. Use the illustration and the measurements above to create a piece needed for the center floor tunnel. The dotted line should Only be used on vehicles equipped with the manual 4x4 shifter. All other vehicles should use one complete piece.



3. For vehicles equipped with a manual 4x4 shifter, it will be necessary to cut out the dotted line area as shown above.



4. Use hot glue to attach the deadener to the top of the floor tunnel as shown above.

Important: Glue the deadener in place to keep it from moving or coming loose.

5. Inspect the center tunnel area for a good fit. If the carpet or rubber is still loose, add another piece of deadener by repeating steps 1-3, or you may add some deadener to the specific area needed.
6. Reposition the carpet or rubber floor covering back into position.
7. Install the body lock pillar trim panels. Refer to Body Lock Pillar Trim Replacement in SI.
8. Install the jack and the jack handle kit. Refer to Jack Stowage Cover Replacement in SI.
9. Install the IP support bracket, bolts and trim covers.
