Beginning with the 1999 model year,
GM introduced a new
generation door hinges on
their truck line. The new generation of hinges were initially only
available on the Silverado/Sierra trucks. But eventually it became
standard on all of the full sized truck line. The new hinge is a very ingenious
design, and some long standing GM door hinge design problems were
effectively addressed. The primary improvement was the elimination of the
“door check” feature from the hinge. The door check, with its’ heavy
spring has resulted in the premature failure of many door hinges. This
feature is now a separate function built into the center portion of the
door jam. The previous design utilized two
pressed in replaceable bushings, and a single pin per hinge. The new hinge
is designed for two non-serviceable, Teflon lined bushings. These Teflon
liners appear to be sacrificial, and allow a certain small amount of
movement within the hinge assembly at the factory. Where as the previous hinge used a
single pin, the new design uses two non-serviceable pins, which are swaged
in place. No service parts are available to
repair the new style hinges. As good as this hinge design is, it can, and
will eventually wear out. Once this happens the only cure is to cut
the body side of the hinge off and bolt a new one on. A
costly process! The door side of the hinge has no moving parts, and
therefore normally does not require replacement. However the two body side
hinges will require replacement, at $103.00 each, and twelve hours labor
for installation. This in itself, adds up to a very costly repair,
and unfortunately this repair will eventually wear out just as the
original did. Therefore we developed a much more
cost effective solution to this problem. Our design can be quickly
installed, and lubricated with a grease gun. After all a lack of
lubrication is the root cause of many door hinge failures. Our
system can be installed by virtually anyone, not necessarily a body
shop. Click here to view a before
