In early 2000 GM replacement hinges began to
incorporate a stamped
sheet metal bushing which utilized TeflonŽ lining inside
the bushings. The lining works very well when the bushing is new,
but the sheer weight of the forces at work within the hinge will
quickly swage
the lining materiel from the bushings. The new style bushings cannot
be replaced with the old style bushings, therefore the new style can
only be replaced with new style. Beginning with the 2003 model year
all new GM medium duty trucks use the new style bushings. The new
style bushing simply cannot match the structural integrity of the
old style bushings. They have a much smaller surface area, of a
stamped construction, and have a TeflonŽ type lining.
We
have developed a special bushing to be used in place of this new
style bushing. Our bushing incorporates a provision for pressure
lubrication, and has enhanced structural integrity. Installation of
our bushing requires drilling the original bushing location slightly
oversize to accept our bushing which is a press fit.
