WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2003 GMC Yukon XL, 2003 GMC Yukon, 2003 Chevrolet Tahoe, 2003 Chevrolet Suburban, and 2003 Chevrolet Avalanche. However, it is still accessible from the selected car via links, so may be relevant.

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 pillar.
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 four weld marks on the original hinge.
Important: Do not drill into the hinge pillar.

Drill through the hinge base only, at each punch location. Use a 13 mm (1/2 in) rotabroach hole saw or 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.
