NO: 23-53-97
GROUP: Body
DATE: Oct. 3, 1997
SUBJECT:
Door Check Roller Repair
MODELS:
1993 - 1997 (ZJ) Grand Cherokee, Grand Wagoneer
1993 - 1997 (ZG) Grand Cherokee
SYMPTOM/CONDITION:
A new door check roller has been released which will allow for the replacement of door check rollers without replacement of the entire hinge assembly.
The roller is an improved design which may also reduce noise associated with the door check rollers used previously. The roller can be used on any ZJ
body vehicle including early models which were equipped with the stamped star wheel type roller.
DIAGNOSIS:
Inspect the door check roller, if the roller is worn, broken or the missing, perform the Repair Procedure.
PARTS REQUIRED:
AR
05011164AA
Door Check Roller (2 required for each front door, 1
required for each rear door)
REPAIR PROCEDURE:
This bulletin involves replacement of the door check roller. The repair requires a qualified welder experienced in MIG welding.
1.
Disconnect the battery negative cable.
2.
Front doors require removal from the vehicle. If the repair is being performed on a rear door, proceed to step 7.
3.
Disconnect the wiring harness and pull the harness boot and harness from the door to allow for door removal.
4.
Scribe marks on the door hinges to facilitate later installation of the door.
5.
Remove the door from the vehicle and place the door on a protected work bench to assure that the paint is not damaged during the repair.
6.
Using a die grinder, grind away the rivet material from the bottom side of the roller shaft. Use care not to remove excessive material from the
hinge.
7.
Remove the roller by tapping it out of the hinge with a punch. If the roller shaft is difficult to remove, it may be necessary to drill the shaft out of
the hinge using a 1/4 inch drill.
8.
The new roller will be welded into place. To facilitate the welding process, remove the plating from the end of the new roller with sand paper.
Install the new roller by pressing it into place with a 3 inch or larger C clamp, using a small socket or suitable tool to prevent any pressure from
being applied to the outer bearing. Applying pressure to the outer bearing will damage the rollers and cause premature failure.
9.
On front doors, repeat the roller removal and installation process for the second roller.
10.
Place a wet rag around the roller bearing to minimize risk of heat damage to the bearing or dust seals. Using a MIG, wire weld process, puddle
weld the bottom of the roller shaft to the hinge. This process requires a qualified welder skilled in MIG welding. The maximum weld build up
cannot exceed 1.0 mm. If the weld build up is in excess of 1.0 mm, the weld must be filed to allow for clearance between the weld and the hinge
when the door is closed.
