REMOVAL PROCEDURE
1. Remove related panels and component.
2. Remove any excess sealer surrounding the existing hinge and scribe the location of the hinge on the hinge pillar.

3. Lightly hand-sand the existing hinge with 100 grit or finer sandpaper in order to locate the 4 welds that attach the hinge to the pillar (Fig. 4-26).
IMPORTANT: Punch the center of the weld so that as much of the weld as possible is removed during the drilling.
4. Center punch each of the four weld marks on the original hinge.
IMPORTANT: Do not drill into the hinge pillar.

5. Drill through the hinge only, at each punch location. Use a 13 mm (1/2 in) rotabroach hole saw or equivalent (Fig. 4-27).
6. Remove the hinge. If necessary, use a chisel in order to separate the hinge from the pillar.
7. Remove all of the remaining weld from the pillar surface in order to ensure a flush fit of the service hinge.
INSTALLATION PROCEDURE
1. Repair any damage done to the pillar during the drilling or the removal.
2. Position the service hinge within the scribe marks on the pillar.
3. Center punch each stud location on the hinge pillar according to the service hinge.
4. Drill a 3 mm (1/8 in) pilot hole at each center punch location.
IMPORTANT: Drill must be exact size.

5. Drill an 11.5 mm (29/64 in) hole at the pilot locations for the studs (Fig. 4-28).
IMPORTANT: Prior to refinishing, refer to the publication GM4901M-D-2000 "GM Approved Refinish Materials" for recommended products. Do not combine paint systems. Refer to paint manufacturer's recommendations.

13. Remove each service nut.
14. Apply a full-bodied caulk to the entire hinge mounting surface in order to ensure a proper seal.
