3. Remove the harness.



4. Remove the spare tire carrier swing arm from the hinge.



5. Remove the striker bolt and sleeve.



6. Remove the latch mechanism bolts, nuts, and spacers.
7. Remove the latch mechanism.
8. Remove the latch mechanism isolator bolts.
9. Remove the latch mechanism isolator.

Note: 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:

Note:  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.

Caution: Refer to Fastener Caution in the Preface section.

4. Once the grease is seen exiting the set screw hole: stop, reinstall the set screw (4).

Tighten
Tighten the set screw to 9 N·m (80 lb in).

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.
8. Reinstall the set screw (4).

Tighten
Tighten the set screw and plug to 9 N·m (80 lb in).

Hinge assembly--Visually check the grease seal (2) for damage, replace as required.

Hinge assembly--Check the hard stop pad (1), replace as required.

Latch assembly--Check the latch isolator (2) for damage, replace as required. Thoroughly clean the latch casting surfaces and bond the NEW isolator in place using LOCTITE Black Max 380® adhesive or equivalent.

Latch assembly--Check for operation and apply Teflon dry lube GM P/N 12371287 (Canadian P/N 10953437) to the latch mechanism (1) as required.

Carrier frame--Check the endgate bump stop (2) rubber for damage, replace if required. Thoroughly clean the surfaces and bond the NEW bump stop in place using LOCTITE Black Max 380® adhesive or equivalent.

Carrier frame--Check the striker sleeve (1) for wear, replace as required.

Carrier frame--Check the lamp (3) for operation.

1. THE CARRIER SHOULD BE LOOSE INSTALLED TO THE VEHICLE.
2. Align the latch casting square, and tighten the bolts to specifications using the sequence shown.

Tighten
Tighten the bolts to 95 N·m (70 lb ft).




3. Swing the carrier into the latch pocket so the striker pin touches the latch mechanism.
4. Insert a shim (1) between the striker bottom and the latch pocket.
5. Early carriers with a red striker sleeve will require a 5 mm shim, all other carriers with a yellow sleeve will require a 3 mm shim.
6. Secure the hinge bolts using the specification shown above.
7. Remove the shim (1), the carrier is now aligned and ready for use.

Note: Thoroughly clean the latch casting surfaces and bond the NEW isolator in place using LOCTITE Black Max 380® adhesive or equivalent.

1. Install the latch mechanism isolator, if necessary.
2. Install the latch mechanism isolator screws.

Tighten
Tighten the screws to 9 N·m (80 lb in).

3. Install the latch mechanism, if necessary.
4. Install the latch mechanism bolts, spacers, and nuts.

Tighten
Tighten the bolts to 25 N·m (18 lb ft).




5. Install the sleeve and striker bolt, if necessary.

Tighten
Tighten the bolt to 22 N·m (16 lb ft).




6. Install the spare tire carrier swing arm to the hinge, if necessary.



7. Install the license plate lamp harness, if necessary.
8. Install the license plate lamp harness to the clips on the carrier.



9. Install the license plate lamp screws, if necessary.

Tighten
Tighten the screws to 2.5 N·m (22 lb in).

1. Install the spare tire carrier to the vehicle. Perform the following steps:

1.1.	Position the spare tire carrier to the rear bumper.

1.2.	Loose install the carrier bolts. Refer to the Service Alignment Procedure above for alignment.

1.3.	Connect the license plate lamp harness electrical connector.




2. Install the spare tire to the spare tire carrier.
3. Install the spare tire mounting nuts.

Tighten
Tighten the nuts to 95 N·m (70 lb ft).




4. Install the spare tire cover (2).
5. Install the spare tire stowage cover nut (1) until snug.
6. Close and ensure that the spare tire carrier is latched.
