Instrument Panel Knee Bolster Pontiac

The knee bolster consists of the following components:

The knee bolster is located in the base of the instrument panel (IP) trim panel. The knee bolster extends across the entire IP assembly. The knee bolster is mounted directly to the IP trim panel. The IP trim panel crosses over the top of the steering column and mounts to the steering column upper support. The steering column filler is the only component of the knee bolster that you may replace. The tie bar is an integral part of the IP assembly.

After a non-deployment accident, visually inspect the knee bolster for damage or deformation. Any visible damage indicates other structural damage. The knee bolster cannot be repaired or replaced separate from the IP assembly, the IP assembly must be replaced.

When replacing the knee bolster, note the GM part number. Compare the part numbers at installation in order to ensure that you are installing the correct knee bolster. Refer to Instrument Panel Assembly Removal .
