An assortment of pry bars, cheater
pipes, wedges and other tools have
been used in an attempt to identify
worn suspension parts. This simple
but ingenious Suspension Wear Indicator
provides a safe and effective replacement for
all of those methods.
To use the tool, a tire is raised off
the ground to allow clearance, then
lowered until some of the vehicle’s
weight rests on the tool. This allows
the suspension to remain in its normal
“as driven” position. With the
tool positioned parallel to the tire
tread, slowly rocking the handle allows the user to check for side-to-side
suspension wear. Placing the tool perpendicular to the tire tread,
then applying the brakes, checks forward and reverse suspension wear.
Two tools can be used at once to simultaneously check for wear on
both sides of a front or rear suspension.
Strut bushings and bearings, link pin bushings, wheel bearings, CV axles,
ball joints, tie-rod ends, steering rack mounts, torsion bar bushings
and control arm bushings all can be checked for wear, play or looseness
with this tool. It allows the user to positively see, feel or hear a problem
while performing suspension diagnostics.
