Subject: SPARE TIRE CARRIER RATTLE
Model and Year: 1986-90 S/T BLAZER TRUCK WITH SPARE TIRE CARRIER (RPO P16)
TO: ALL CHEVROLET DEALERS
Owners of some 1986 through 1990 S/T Blazers equipped with factory installed spare tire carriers (RPO P16) may comment on a rattle condition coming from the spare tire carrier area. This rattle condition may result from vehicle and road vibrations which are transmitted through the vehicle to the spare tire carrier region. This vibration changes to a rattle in any of the following three locations.
TAILGATE
Mode of vibration is a side to side motion of the tailgate and is caused by the tailgate not being properly aligned into the opening when closed.
SPARE TIRE CARRIER
This second form of vibration occurs in a forward and backward motion relative to the vehicle. Again, this is due to the tire carrier not being tightly held in place. This motion creates a rattle between the striker assembly and the carrier latch, and/or the carrier arm and the striker plate.
WINDOW LATCH
This third form of vibration can occur in the window latch region. This rattle noise is caused by the vibrations mentioned above and occurs as the window guide vibrates in the guide bushing (see Figure 6).
The following four procedures can be done in any order as a single or as a multiple repair.
