SPARE TIRE CARRIER RATTLE CARRIER LATCH/BUMPER ADJ. #91-356-10 - (05/29/1991)
Subject: SPARE TIRE CARRIER RATTLE

Model and Year: 1990-91 S/T TRUCKS

FOR ADDITIONAL INFORMATION ON SPARE TIRE CARRIER AND ENDGATE RATTLES, PLEASE REFERENCE DEALER SERVICE BULLETIN NO. 90-33O-3E, DATED AUGUST, 1990 AND CHEVROLET DCS MESSAGE NO. 01-330, DATED NOVEMBER 16,1990.1990.

Some owners of 1990-91 S/T utility vehicles equipped with factory installed RPO P16 may experience a rattle condition from the spare tire carrier assembly, 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.

VEHICLES INVOLVED

NOTE: All 1991 Chevrolet vehicles were equipped with factory installed rubber bumper assemblies.

1990 model vehicles built prior to the following VIN's were not factory equipped with a rubber bumper assembly:

Shreveport: 1GNCS18ZXM8104025

PontiacWest: 1GNCT18Z0M0101419

Moraine: 1GNDT13Z6M2115163

(Current design carrier assembly arms with rubber bumpers may have been installed by dealers per Dealer Service Bulletin No.90-330-3E, dated dated August 1990.

To correct, it is necessary to insure 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.

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 25-35 N.m (1 8-26 lbs. ft.).

Had a buddy with the same problem and tried everything to get rid of it.It turned out it was not the spare tire but the pins that hold the tailgate on.One drop of oil on each pin and that aggravating squeaking was gone forever.Drop the tailgate down and oil them up and you may get some piece and quiet

I have a 93 blazer and the squeek is comming from the rear window where it meets up with the seal by the latch. I lubed the rear wheel, tailgate hinges with no help. Then one day while driving, I put it in Nuetural and popped the rear window and the squeek went away. I've been spraying silicone, wiping vasoline on the seal and the squeel will subside for a couple days and then return. I think I need to adjust the tension of the rear window latch so it doesn't seat as tight. But try this if you can't find the squeek in the spare tire.

The back window on my 93 blazer squeaks also. The way I fixed it and has not squeaks for about 3 months and still going, is putting grease in the latch assembly, it helps really well for mine.

I also greased the rear window latch assembly, problem gone, I screwed with that Tire carrier assembly for awhile, finally I decided that I would grease the window U shape pin. Someone told me once that the metal of the pin on the rear window is stronger than the metal of the latch so after awhile it wears some space into the latch.
