Condition
Some customers may comment on front door hinge pin bushing wear, front door sag, or door chucking movement in extreme operating conditions. Hinge
pin and bushing wear or damage is commonly found on vehicles that operate where there is a very high number of door opening or closing cycles per day
(over 100 times) or in an extremely dusty or dirty environment. If this wear is not addressed early, the door hinge may separate from the sheet metal.
Cause
The condition may be caused from excessive force on the bushing at the door stop. Worn or damaged hinge pins or bushings may cause the door to sag.
This may prevent the door from closing properly. If the hinge pin bushings are worn, and this condition is not corrected, the hinge pin may wear through
the bushing and into the metal of the hinge.
Correction
Three situations have been identified with the appropriate correction listed below.
Situation 1 - The hinge bushings, the hinge pins, or the door stop check pin are worn or damaged.
1.
If necessary, replace the door stop check pin.
2.
If necessary, replace the hinge bushings and the stop pins.
3.
Add a door trim strap assembly.
4.
Install a severe service kit, P/N 15025840 with new Teflon(R) bushings and anti-chucking spacer.
5.
Lubricate the door hinge. Lubricate the door hinge at each oil change as part of ongoing preventative maintenance.
Situation 2 - The door hinges are damaged in the bushing area and new replacement hinges are needed.
