File In Section: 10 - Body

Date: November, 1995
Subject:
Doors are Hard to Open (Install New Door Hinge Assemblies with Teflon Coated Bushings, Front, Side Cargo, or Back Cargo Swing out Doors)
Models:
1986-95 Chevrolet G Vans Built Prior to VIN Breakpoint SF617824
1986-95 GMC Truck G Vans Built Prior to VIN Breakpoint SF219844
excluding Sliding Side Doors
Condition
Owners may report one or more doors are difficult to open and/or close due to binding. This condition is noticed either while trying to swing the door
out, or trying to close the door in its latched position.
Cause
Metal to metal interaction between the door hinge pin and bronze hinge pin bushing. Metal to metal reaction may allow corrosion, or environmental
contaminates may dry out hinge pin lubricants.
Correction
Improved door hinges have been developed for all swing out door assemblies. The front, side cargo, and back cargo door hinges now have a Teflon
coated hinge pin bushing that allows the doors to swing with less resistance. Install new door hinges if the above condition exists. It may not be necessary
to remove all hinges. Repair only the hinge/hinges that are binding.
Service Procedure
Important:
The new hinge assembly should be painted and cured prior to assembly. Locate the Service Parts Identification label inside the glove box for the
exterior paint code.
