Condition
Some customers may comment on hearing a pop noise coming from rear roof of cab area. The sound may even be described like a rock, or other object, striking the cab.
The sound is also more commonly heard when the cab body is heated, or cooled, by changes in ambient conditions.
Cause
Note: In the graphic examples above, a gap (1) can be noted on the passenger side lower corner of CHMSL. In the second example a slight wear mark (2) in the spoiler paint can be seen.
The cause of the condition may be an Interference between the Center High Mount Stop Lamp (CHMSL) and the body of the spoiler. As these parts expand and contract, with the changes in ambient conditions, there is a stick-slip condition that generates noise.
Correction
Following the steps in the Service Procedure below, apply foam tape between the CHMSL and the spoiler body, to create space between the CHMSL and spoiler.
Service Procedure
Important: Discard the 8 original central roof spoiler nuts, they are NOT reusable fasteners.
1. Remove the roof rear spoiler from the vehicle, and the CHMSL (2) from the spoiler. Refer to High Mount Stop Lamp Replacement, in SI,
2. Cut an approximate 45 mm. (1.75 in.) length of *Kent Automotive Adhesive-Back Shim Stock P/N P40100, or equivalent. Then cut that piece in half, lengthwise.
3. Apply 1 piece of tape, to each side of the lower corners of the spoiler, in these areas shown by the arrows in the graphic above.
Important: The 8 central roof spoiler nuts are NOT reusable fasteners. The original fasteners must be discarded and replaced.
4. Reinstall the CHMSL, and the roof rear spoiler. Refer to High Mount Stop Lamp Replacement, in SI,
5. Verify the noise condition has been eliminated.
