Removal Procedure
1. Remove the door from the body.
2. Remove any excess sealer surrounding the hinge and scribe the location of the hinge on the door.
3. Lightly hand-sand the existing body 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 is removed during the drilling as possible.
4. Center punch each of the 4 weld marks on the original hinge base.
Important: Do not drill into the door (1).
5. Drill through hinge base only (2) at the punch location. Use a 13 mm (1/2 in) rotabroach hole saw (3) or the equivalent.
6. Remove hinge. If necessary, use a chisel to separate the hinge from the door.
7. Remove all of the remaining weld from the door surface in order to ensure a flush fit of the service hinge.
