SPARE TIRE CARRIER RATTLE CARRIER LATCH/BUMPER ADJ.

SUBJECT: SPARE TIRE CARRIER RATTLE CUSTOMER AWARENESS OF 2 POSITION LATCH/BUMPER ADJUSTMENT

MODELS/YEARS: 1991 BRAVADA WITH OPTION P16

Some owners of 1991 Bravadas equipped with a factory installed outside spare tire carrier, (RPO P16) may experience a rattle condition while driving. This condition can occur if the spare tire carrier second (primary) latch position is not engaged and/or the rubber bumper assembly is improperly adjusted.

To correct this condition, it is necessary to insure that owners are familiar with the double position latch mechanism and that the carrier is fully closed engaging the second latch position (Figure 1).

SERVICE PROCEDURE (Figures 1-4):

1. Grasp the spare tire and shake the carrier assembly (Figure 1) to determine if the second latch position is engaged. If the second latch position is NOT engaged, the spare tire carrier assembly will be loose and rattle. If the second latch position IS engaged, the spare tire carrier should not move (Figures 2-3).

2. If the carrier is improperly shut, open and close engaging the second latch position. Recheck by grasping the spare tire and shaking the carrier assembly to insure the carrier is properly closed.

Note: DRIVER/OWNER MAY NOT BE AWARE OF SECOND LATCH POSITION AND SHOULD BE INFORMED OF PROPER CLOSING INSTRUCTIONS.

3. If a rattle condition still exists, the bumper may be misadjusted. Test drive the vehicle to determine if the rattle has been eliminated.

Note: If rattle has been eliminated with proper closing, it is NOT necessary to perform Step 4.

4. If a rattle still exists with second latch position engaged, open the spare tire carrier and loosen the, adjustment nut located on the bumper assembly (Figure 4).

Close the carrier assembly, engaging the second latch position, and adjust the rubber bumper until it contacts the striker plate surface on the tailgate. To complete the adjustment, open the carrier and rotate the bumper counterclockwise an additional one and one-half (1-1/2) turns preloading the bumper against the striker plate surface.

Tighten the adjustment nut against the face of the mounting bracket. Torque the adjustment nut to 30 N - m (22 lbs. ft.).
