WIPER ARM
DESCRIPTION
FRONT
The front wiper arms are the rigid members located
between the wiper pivots that protrude from the cowl
plenum cover/grille panel near the base of the wind-
shield and the wiper blades on the windshield glass.
These wiper arms feature an over-center hinge that
allows easy access to the windshield glass for clean-
ing. The wiper arm has a die cast metal pivot end (4)
with a large tapered mounting hole (5) at one end. A
molded black plastic cap fits over the wiper arm
retaining nut to conceal the nut and this mounting hole
following wiper arm installation.
The wide end of a tapered, stamped steel channel (3) hinges on and is secured with a hinge pin (6) to the blade
end of the wiper arm pivot end. One end of a long, rigid, stamped steel strap (2) with a small hole near its pivot end
is riveted and crimped within the narrow end of the stamped steel channel. The tip of the wiper blade end of this
strap is bent back under itself to form a small hook (1). Concealed within the stamped steel channel, one end of a
long tension spring (7) is engaged with a wire hook on the underside of the die cast pivot end, while the other end
of the spring is hooked through the small hole in the steel strap. The entire wiper arm has a satin black finish
applied to all of its visible surfaces.
A wiper arm cannot be adjusted or repaired. If damaged or inoperative, the entire wiper arm unit must be replaced.
REAR
The rear wiper arm is the rigid member located
between the rear wiper motor output shaft that pro-
trudes from the outer tailgate panel near the base of
the rear flip-up glass opening and the rear wiper
blade. This wiper arm features an over-center hinge
that allows easy access to the tailgate and rear flip-up
glass for cleaning, after the spare tire is removed. The
wiper arm has a die cast metal pivot end (6) with a
large tapered mounting hole at one end. A molded
plastic pivot cover (5) is secured loosely to and pivots
on the wiper arm hinge pin (4) to conceal the wiper
arm retaining nut.
The wide end of a tapered, stamped steel channel (3) is secured with a hinge pin to the pivot end of the wiper arm.
One end of a long, rigid, stamped steel strap (2) with a small hole near its pivot end is riveted and crimped within
the narrow end of the stamped steel channel. The tip of the wiper blade end of this strap is bent back under itself
to form a small hook (1). Concealed within the stamped steel channel, one end of a long tension spring (7) is
engaged with a wire hook on the underside of the die cast pivot end, while the other end of the spring is hooked
through the small hole in the steel strap. A molded plastic wiper arm support (8) is snapped onto the wiper arm
strap where it exits the channel. The entire wiper arm has a satin black finish applied to all of its visible surfaces.
A wiper arm cannot be adjusted or repaired. If damaged or inoperative, the entire wiper arm unit must be replaced.
