Some vehicles may exhibit a condition of loose or rattling wheel hubcaps, especially on the front positions.

This may be the result of brake heat distortion of the functional nut caps on the wheels.

DO THIS

DON'T DO THIS

Replace ONLY the functional nut caps.

DO NOT replace the entire hubcap assembly.

If this condition is encountered, only the functional nut caps in the hubcap assembly should be replaced, NOT the entire hubcap assembly.

New functional nut caps, P/N 9596657, are now available. These new caps consist of more heat resistant material and are less susceptible to heat distortion. The new functional nut caps are dark gray in color. The original caps are black. Therefore, ALL functional nut caps on the vehicle must be replaced (24 functional nut caps on 6 bolt vehicles and 32 functional nut caps on 8 bolt vehicles).

The old (black) functional nut caps should be snapped out of the hubcaps, and the new (dark gray) functional nut caps snapped back into place. When installing the hubcaps back on the vehicle, refer to Corporate Bulletin Number 03-03-10-002A, Use of Correct Installation Procedure for Loose Hubcap Assembly (SI Document ID #1530155) for the correct procedure for tightening the nut caps.
