FRONT WIPER ARM
DESCRIPTION
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
(Fig. 9). These wiper arms feature an over-center hinge
that allows easy access to the windshield glass for
cleaning. The wiper arm has a die cast metal pivot end
with a large tapered mounting hole at one end. A
molded black plastic cap fits over the wiper arm retain-
ing nut to conceal the nut and this mounting hole fol-
lowing wiper arm installation. The wide end of a
tapered, stamped steel channel hinges on and is secured
with a hinge pin to the blade end of the wiper arm pivot
end. One end of a long, rigid, stamped steel strap, 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. Concealed within the
stamped steel channel, one end of a long spring is
engaged with a wire hook on the underside of the diecast 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 faulty, the entire wiper arm unit must be
replaced.
OPERATION
The front wiper arms are designed to mechanically
transmit the motion from the wiper pivots to the wiper
blades. The wiper arm must be properly indexed to the
wiper pivot in order to maintain the proper wiper blade
travel on the glass. The tapered mounting hole in the
wiper arm pivot end interlocks with the serrations on
the tapered outer circumference of the wiper pivot shaft,
allowing positive engagement and finite adjustment of
this connection. The mounting nut locks the wiper arm
to the threaded stud of the wiper pivot shaft. The
spring-loaded wiper arm hinge controls the down-force
applied through the tip of the wiper arm to the wiper
blade on the glass. The hook formation on the tip of the
wiper arm provides a cradle for securing and latching
the wiper blade pivot block to the wiper arm.
REMOVAL
(1) Lift the front wiper arm to its over-center posi-
tion to hold the wiper blade off of the glass and
relieve the spring tension on the wiper arm to wiper
pivot shaft connection.
(2) Carefully pry the plastic nut cap off of the
pivot end of the wiper arm (Fig. 10).
(3) Remove the nut that secures the wiper arm to
the wiper pivot shaft.

(4) If necessary, use a suitable battery terminal
puller to disengage the wiper arm from the wiper
pivot shaft (Fig. 11).
(5) Remove the front wiper arm pivot end from the
wiper pivot shaft.
INSTALLATION
NOTE: Be certain that the wiper motor is in the park
position before attempting to install the front wiper
arms. Turn the ignition switch to the On position
and move the control knob on the right (wiper) con-
trol stalk of the multi-function switch to its Off posi-
tion. If the wiper pivots move, wait until they stop
moving, then turn the ignition switch back to the
Off position. The wiper motor is now in its park
position.
(1) The front wiper arms must be indexed to the
wiper pivot shafts with the wiper motor in the park
position to be properly installed. Position the front
wiper arm pivot ends onto the wiper pivot shafts so
that the tip of the wiper blade is aligned with the
T-shaped wiper alignment lines located in the lower
edge of the windshield glass (Fig. 10).
(2) Once the wiper blade is aligned, lift the wiper
arm away from the windshield slightly to relieve the
spring tension on the pivot end and push the pivot
hole on the end of the wiper arm down firmly and
evenly over the wiper pivot shaft.
(3) Install and tighten the nut that secures the
wiper arm to the wiper pivot shaft. Tighten the nut
to 24 N´m (18 ft. lbs.).
(4) Wet the windshield glass, then operate the
front wipers. Turn the front wipers Off, then checkfor the correct wiper arm position and readjust as
required.
(5) Reinstall the plastic nut cap onto the wiper
arm pivot nut.
FRONT WIPER BLADE
DESCRIPTION
Each front wiper blade is secured by an integral
latching pivot block to the hook formation on the tip
of the front wiper arms, and rests on the glass near
the base of the windshield when the wipers are not
in operation (Fig. 12). The wiper blade consists of the
following components:
²Superstructure- The superstructure includes
several stamped steel bridges and links with claw
formations that grip the wiper blade element. Also
included in this unit is the latching, molded plastic
pivot block that secures the superstructure to the
wiper arm. The driver side front wiper blade has an
additional molded black plastic airfoil secured to the
superstructure, which is oriented toward the base of
the windshield when the front wipers are in their
parked position. All of the metal components of the
wiper blade have a satin black finish applied.
²Element- The wiper element or squeegee is the
resilient rubber member of the wiper blade that con-
tacts the glass.
²Flexor- The flexor is a rigid metal component
running along the length of each side of the wiper

FRONT WIPER ARM (Continued)

A wiper arm cannot be adjusted or repaired. If
damaged or faulty, the entire wiper arm unit must be
replaced.
OPERATION
The rear wiper arm is designed to mechanically
transmit the motion from the rear wiper motor out-
put shaft to the rear wiper blade. The wiper arm
must be properly indexed to the motor output shaft
in order to maintain the proper wiper blade travel on
the glass. The wiper arm support is designed to lift
and support the rear wiper arm and blade off of the
glass when the rear wiper blade is parked. This sup-
port and the park ramp on the tailgate outer panel
below the glass also provide an alignment reference
to ensure accurate rear wiper arm and blade instal-
lation. The tapered hole in the wiper arm pivot end
is interlocks with the serrations on the outer circum-
ference of the tapered motor output shaft, allowing
positive engagement and finite adjustment of this
connection. A hex nut secures the wiper arm pivot
end to the threads on the rear wiper motor output
shaft and the pivot cover hinges and snaps over this
connection for a neat appearance. The spring-loaded
wiper arm hinge controls the down-force applied
through the tip of the wiper arm to the wiper blade
on the glass. The hook formation on the tip of the
wiper arm provides a cradle for securing and latching
the wiper blade pivot block to the wiper arm.
REMOVAL
(1) Lift the rear wiper arm pivot cover by lifting it
at the rear wiper motor output shaft end of the arm
(Fig. 9).
(2) Remove the nut that secures the rear wiper
arm to the rear wiper motor output shaft.
(3) If necessary, use a battery terminal puller to
disengage the wiper arm from the rear wiper motor
output shaft splines (Fig. 10).
NOTE: Depending upon the size and type of puller
used, it may be necessary to remove the spare tire
from the tailgate. Refer to the owner's manual in the
vehicle glove box for information on removing the
spare tire from the tailgate.
(4) Remove the rear wiper arm pivot end from the
motor output shaft.
INSTALLATION
NOTE: Always install the wiper arm and blade with
the wiper motor in the Park position.
(1) The rear wiper arm must be indexed to the
motor output shaft with the rear wiper motor in the
park position to be properly installed. Place thewiper arm onto the tailgate with the wiper arm sup-
port positioned on the park ramp and the tapered
mounting hole on the pivot end of the arm positioned
over the rear wiper motor output shaft.
(2) Position the tab on the back of the rear wiper
arm support on the tailgate park ramp in the Instal-
lation Position (Fig. 11).
(3) With the wiper arm in the Installation Posi-
tion, push the tapered mounting hole on the pivot
end of the wiper arm down over the rear wiper motor
output shaft.

(2) To determine if the secondary timing chains
are worn, rotate the engine clockwise until maximum
tensioner piston extension is obtained. Measure the
distance between the secondary timing chain ten-
sioner housing and the step ledge on the piston. The
measurement at point (A) must be less than 15mm
(.5906 inches).
(3) If the measurement exceeds the specification
the secondary timing chains are worn and require
replacement. Refer to Timing Chain and Sprockets in
this section for procedure.
SERVICE PROCEDURES
TIMING VERIFICATION
CAUTION: The 3.7L is a non free-wheeling design
engine. Therefore, correct engine timing is critical.
NOTE: Components referred to as left hand or right
hand are as viewed from the drivers position inside
the vehicle.
NOTE: The blue link plates on the chains and the
dots on the camshaft drive sprockets may not line
up during the timing verification procedure. The
blue link plates are lined up with the sprocket dots
only when re-timing the complete timing drive.
Once the timing drive is rotated blue link-to-dot
alignment is no longer valid.
Engine base timing can be verified by the following
procedure:
(1) Remove the cylinder head covers. Refer to the
procedure in this section.
(2) Using a mirror, locate the TDC arrow on the
front cover (Fig. 91). Rotate the crankshaft until the
mark on the crankshaft damper is aligned with the
TDC arrow on the front cover. The engine is now at
TDC.
(3) Note the location of the V6 mark stamped into
the camshaft drive gears. If the V6 mark on each
camshaft drive gear is at the twelve o'clock position,
the engine is at TDC on the exhaust stroke. If the V6
mark on each gear is at the six o'clock position, the
engine is at TDC on the compression stroke. (Fig. 95)
(4) If both of the camshaft drive gears are off in
the same or opposite directions, the primary chain or
both secondary chains are at fault. Refer to Timing
Chain and Sprockets procedure in this section.
(5) If only one of the camshaft drive gears is off
and the other is correct, the problem is confined to
one secondary chain. Refer to Single camshaft tim-
ing, in this procedure.(6) If both camshaft drive gear V6 marks are at
the twelve o'clock or the six o' clock position the
engine base timing is correct. Reinstall the cylinder
head covers.
COUNTER BALANCE SHAFT TIMING
(1) Ensure that the engine is at TDC with both
camshaft sprocket marks are in the 12 o'clock posi-
tion. (Fig. 94)
(2) Look down the left cylinder gear chain cavity.
The timing dot on the counter balance shaft drive
gear should be in the 6 o'clock position (Fig. 92).
TIMING - SINGLE CAMSHAFT
NOTE: to adjust the timing on one camshaft, pre-
form the following procedure.
(1) Using Chain Tensioner Wedge, Special Tool
8379, stabilize the secondary chain drive. For refer-
ence purposes, mark the chain-to-sprocket position.
(Fig. 93)
(2) Remove the camshaft drive gear retaining bolt.
(3) Carefully remove the camshaft drive gear from
the camshaft.
(4) Re-index the camshaft drive gear in the chain
until the V6 mark is at the same position as the V6
mark on the opposite camshaft drive gear.
