Service Procedure
1.
Position J 41226-4 template around upper hinge and tape to vehicle.
Important:
When repairing a Suburban, you must remove .020" from the top of the hinge pins using a file or grinder. (This will remove the case hardness to ease
the drilling process.)
2.
Install J 41226-2 small drill guide bushing to J 41226-1 drill fixture.
Important:
The drill guide bushings are two sided to fit the top of the door hinge pins. Make sure to install the proper end that best fits the hinge pin head to
ensure center for drilling.
3.
Install J 41226-1 drill fixture onto hinge assembly and tighten lower screw to secure fixture to hinge.
4.
Remove J 41226-11 small drill from the container and install J 41226-15 drill stop collar 1-3/4" from the drill point.
Important:
In most cases, drilling through the first quarter of the hinge should be sufficient to remove hinge pin, however some pins may require additional
drilling at which time the stop collar is no longer needed.
