DOOR HINGE REPL.-NEW POLICIES, PROC. & LABOR ALLOW. (W CAR)
SUBJECT: DOOR HINGE REPLACEMENTS - NEW POLICIES, PROCEDURES AND LABOR ALLOWANCES
MODEL/YEARS: 1989-1992 CUTLASS SUPREME
New policies, procedures and labor time allowances have been developed regarding door hinge servicing on 1989 models built after vehicle number KD313505 through the end of 1992 production for both coupes and sedans.
POLICY: If a single door hinge on any door at any location requires replacement, the second or remaining hinge must be replaced at the same time.
SERVICE PARTS: Service parts are packaged in "door sets", or two hinges in each package and are currently available from GMSPO. New part numbers are as follows:
PART NUMBER DESCRIPTION ----------- ----------- 10218445 Hinges, Right Front Door 10218446 Hinges, Left Front Door 10218447 Hinges, Right Rear Door 10218448 Hinges, Left Rear Door
PROCEDURES FOR REPLACEMENT
Important: This procedure differs from the previous procedure (Removing the door from the vehicle) in that:
A. The door remains on the vehicle.
B. Access to both front door hinges is made through the front wheel house area.
C. The hinges come pre-primed.
Important: With regard to both front and rear doors, in order to minimize door realignment, DO NOT remove both door hinges at the same time. Do each hinge separately, and replace any broken hinges first.
Front Doors
1. Place vehicle on hoist.
2. Using the proper lift points, raise vehicle to half up position (until wheel/tire is chest high).
Important: Make sure that the doors are fully latched onto the lock striker and the doors are not locked.
3. Using two pieces of masking tape, place one piece to bridge the gap between the door and rocker panel and the second piece to bridge the gap between the door and quarter panel or rear door (to act as reference points for door alignment).
4. Cut the tape at the gap area using a utility knife or other suitable tool.
5. Remove the front tire and wheel assembly.
6. Starting at the top center of the front wheel house liner, remove all attaching screws located rearward of the top center of the liner.
7. Loosen the liner from the fender and position the liner forward of the front suspension assembly.
8. Remove the insulator cover attachments and insulator cover (located between fender and hinge pillar).
9. Clean the hinge mounting surfaces on the door and body with a rag and mark the hinge locations on the body surfaces with a grease pencil or other suitable marker.
10. Remove the hinge attaching the fasteners and hinge from vehicle.
11. Install the new hinge within the previously marked locations using the new fasteners and lightly tighten the fasteners.
12. Repeat steps 10 and 11 for remaining hinge.
13. Install tire/wheel with 3 nuts and lower the vehicle to ground level.
14. Inspect the edges of the tape on the door and with the aid of a helper, align the door as necessary.
15. Raise the vehicle to the previous position and remove the tire/wheel assembly.
16. Tighten and torque the hinge attachments to:
Bolts - 46 N.m (34 Lbs. Ft.) Nuts - 27 N.m (20 Lbs. Ft.)
17. Reinstall the insulator cover.
18. Reposition and install the wheelhouse liner using the original screws.
19. Reinstall the tire and wheel assembly. Torque wheel nuts to 140 N.m (I 00 Lbs. Ft.).

Important: Make sure that the doors are fully latched onto the lock striker and the doors are not locked.

General Motors bulletins are intended for use by professional technicians, not a "do-it-yourselfer". They are written to inform those technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions and know-how to do a job properly and safely. If a condition is described, do not assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See a General Motors dealer servicing your brand of General Motors vehicle for information on whether your vehicle may benefit from the information.
