Some 1985-1986 C/K models and 1987 R/V models may have inside front and rear door handles that are misaligned. This misalignment may result in difficulty in getting fingers around the handle to release the latch. This condition is due tothe rubber bumper shown in Figure 1 coming loose from the door handle bumper post. The rubber bumper may still be in t@he door handle assembly or it may have fallen inside the door. If the rubber bumper cannot be located or is damaged, a 3/8" piece of 1/4" I.D. x 1/2" O.D. rubber fuel line may be substituted.
To repair this condition, the following procedure can be used:
1. Remove door trim panel.
2. Remove door handle from door.
3. Clean rubber bumper and bumper post of oil, grease and dirt.
4. Apply 'Loctite Black Max' adhesive or equivalent, to the bumper post.
5. Install bumper.
6. Reinstall door trim panel.

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.
