Squeak, Rub/Scrub Type Noise in Steering Column (Lubricate Upper Intermediate Shaft Serration (Slip) Joint and Remove Material from Upper Intermediate Shaft Bushing)

This bulletin is being revised to change the lubricant part number. Please discard Corporate Bulletin Number 02-02-35-006A (Section 02 -- Steering).

Some customers may comment on a squeak noise coming from the steering column while turning the steering wheel. Some customers may also comment on a rubbing/scrubbing type noise/feel in the steering wheel during low speed turns/parking maneuvers. This condition may be more pronounced in cold temperatures.

The rubbing/scrubbing noise condition affects vehicles built prior to VIN breakpoint 32214010 (Moraine, OH) and 36170447 (Oklahoma City, OK).

Inadequate distribution and amount of grease in the serration (slip) joint of the upper intermediate shaft may cause the squeak noise. The rubbing/scrubbing type noise may be due to an interference fit between the upper intermediate shaft boot seal and the intermediate shaft bushing.

Lubricate the upper intermediate shaft serration (slip) joint. After lubrication, remove material from the upper intermediate shaft bushing. Use the following procedure.

1. Remove the two screws that retain the left closeout/insulator panel to the instrument panel (IP).
2. Release the insulator panel retaining clip from the IP substrate and lower the panel.
3. Remove the push pin retainer and the LH floor air outlet duct from the heater module.



4. Insert the flexible applicator hose of the spray lubricant, P/N 89021668 (Canadian P/N 89021674), through the top, hollow end (1) of the intermediate shaft.
5. With the applicator hose down as far as possible toward the mating area of the serrations, spray a generous amount of grease.
6. Repeat the application after rotating the steering wheel 180 degrees, so that the serrations are treated in two locations opposite each other.
7. Position the floor air outlet duct into place and install the push pin retainer.
8. Raise the insulator panel and install the retaining clip to the IP substrate.
9. Install the two screws that retain the left closeout/insulator panel to the IP.

Use the following steps to remove material from the upper intermediate shaft bushing.

1. Push the upper intermediate shaft boot seal (2) down toward the floor in order to completely expose the white bushing (1).
2. Using fine or very fine sandpaper, remove material from the intermediate shaft bushing. Sand around the entire face of the bushing sufficient enough to obtain clearance and reduce the drag between the intermediate shaft bushing and the upper boot seal.
3. Return the upper intermediate shaft boot seal to its original position.
4. Clean debris as necessary.
