Important: The spare tire carrier requires items inspected and/or replaced at scheduled vehicle service intervals.





Check the carrier swing arm articulation and latching performance as follows:
^ The swing arm closing effort is not to be excessive.Adjust the latch assembly, as required.
^ The swing arm is to kick back beyond the latch casting after the latch handle is operated.Adjust the latch assembly, as required.

Important: Under normal conditions the hinge assembly will NOT require lubrication.





Hinge assembly - If the hinge assembly needs to be greased, due to removal, the plug needs to be removed and lubricated as stated below using GM P/N 89022180 (Canadian P/N 89022181).
1. Remove the M6 set screw (4).
2. Remove the 1/4 inch plug above the set screw.
3. Install a grease (zerk) fitting (3) where the 1/4 inch plug was, apply grease, rotate the swing arm to ensure a uniform coating over the internal bushing.
4. Once the grease is seen exiting the set screw hole: stop, reinstall the set screw (4).
Tighten the set screw to 9 N.m (80 lb in).

Notice: Refer to Fastener Notice in Service Precautions.

5. Again, grease via the zerk fitting (3), continue articulating the swing arm until grease is just visible on the casting grease seal (2). DO NOT ALLOW THE SWING ARM TO LIFT DURING LUBRICATION. If the swing arm lifts, remove the set screw (4) and apply downward pressure while rotating the swing arm. Continue until the swing arm makes contact with the casting.
6. The hinge is now primed with the correct amount of grease.
7. Remove the zerk fitting (3) and reinstall the 1/4 inch plug.
