Removal Procedure
- Remove all of the related panels and components.
 
- Remove any excess sealer surrounding the existing hinge and scribe  the location of the hinge on the hinge pillar.
 
- 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 door.
 
Important: Punch the center of the weld so that as much of the weld as possible  is removed during the drilling.
- Center punch each of the 4 weld marks on the original hinge.
 
Important: Do not drill into the hinge pillar.
- Drill through the hinge only at each punch location. Use a 13 mm  (1/2 in) rotabroach hole saw or the equivalent.
 
- Remove the hinge. If necessary, use a chisel in order to separate  the hinge from the pillar.
 
- Remove all of the remaining weld from the pillar surface in order  to ensure a flush fit of the service hinge.
 
Installation Procedure
- Repair any damage done  to the pillar during the drilling or the removal.
 
- Position the service hinge within the scribe marks on the pillar.
 
- Center punch each stud location on the hinge pillar according  to the service hinge  (1).
 
- Drill a 3 mm (1/8 in) pilot hole (2) at each center  punch location.
 
Important: The drill bit must be the exact size.
- Drill an 11.5 mm (29/64 in) hole at the pilot locations  for the studs.
 
- Clean and prepare all of the bare metal surfaces.
 
Important: Prior to refinishing, refer to the publication GM 4901M-D-2000  GM Approved Refinish Materials for recommended products. Do not combine paint        systems.  Refer to manufacturer's recommendations.
- Apply an approved anti-corrosion primer.
 
- Feed fish wire, GM P/N 15017229 of the equivalent,  through the hinge (1), the hinge stud hole and out of the conduit hole    in the      pillar.
 
- Install the stud, GM P/N 15017230,  supplied with the service hinge, into the wire end. Pull the stud into position.
 
- Hold the stud in position with the hinge and remove the fish wire.
 
- Draw the stud (4) tight through the pillar. Use the nuts  GM P/N 11516746, supplied.
 
- Repeat steps 7 through 10 on the remaining stud locations.
 
- Remove each service nut.
 
- Apply a full-bodied caulk to the entire hinge mounting surface  in order to ensure a proper seal.
 
- Install the hinge (2) to the pillar (3). Use the  supplied nuts (1).
 
Notice: Use the correct fastener in the correct location. Replacement fasteners
must be the correct part number for that application. Fasteners requiring
replacement or fasteners requiring the use of thread locking compound or sealant
are identified in the service procedure. Do not use paints, lubricants, or
corrosion inhibitors on fasteners or fastener joint surfaces unless specified.
These coatings affect fastener torque and joint clamping force and may damage
the fastener. Use the correct tightening sequence and specifications when
installing fasteners in order to avoid damage to parts and systems.
- Install the hinge (2)  to the pillar (3). Use the supplied nuts  (1).
 
Tighten
Tighten the hinge nuts (4) to 25 N·m (18 lb ft).
- Clean and prepare all of the surfaces as necessary for refinishing.
 
- Apply the sealers. Refinish the surfaces as necessary.
 
- Install and align all of the related panels and the components.
