CABLE TENSIONER
ADJUSTMENTS
ADJUSTMENT
NOTE: Tensioner adjustment is only necessary
when the tensioner, or a cable has been replaced or
disconnected for service. When adjustment is nec-
essary, perform adjustment only as described in the
following procedure. This is necessary to avoid
faulty park brake operation.
(1) Raise the vehicle.
(2) Back off the cable tensioner adjusting nut to
create slack in the cables.
(3) Remove the rear wheel/tire assemblies. Then
remove the brake rotors (Refer to 5 - BRAKES/HY-
DRAULIC/MECHANICAL/ROTORS - REMOVAL).
(4) Verify the brakes are in good condition and
operating properly.
(5) Verify the park brake cables operate freely and
are not binding, or seized.
(6) Check the rear brake shoe adjustment with
standard brake gauge (Refer to 5 - BRAKES/PARK-
ING BRAKE/SHOES - ADJUSTMENTS).
(7) Install the rotors (Refer to 5 - BRAKES/HY-
DRAULIC/MECHANICAL/ROTORS - INSTALLA-
TION) and verify that the rotors rotate freely
without drag.
(8) Install the wheel/tire assemblies, (Refer to 22 -
TIRES/WHEELS/WHEELS - STANDARD PROCE-
DURE).
(9) Lower the vehicle enough for access to the park
brake foot pedal. Then fully apply the park brakes.
NOTE: Leave park brakes applied until adjustment
is complete.
(10) Raise the vehicle again.
(11) Mark the tensioner rod 6.35 mm (1/4 in.) from
edge of the tensioner (Fig. 85).
(12) Tighten the adjusting nut on the tensioner rod
until the mark is no longer visible.
CAUTION: Do not loosen, or tighten the tensioner
adjusting nut for any reason after completing
adjustment.
(13) Lower the vehicle until the rear wheels are
15-20 cm (6-8 in.) off the shop floor.
(14) Release the park brake foot pedal and verify
that rear wheels rotate freely without drag. Then
lower the vehicle.

REMOVAL
(1) Remove the front rotor (Refer to 5 - BRAKES/
HYDRAULIC/MECHANICAL/ROTORS -
REMOVAL).
(2) Remove the wheel speed sensor mounting bolt
from the hub. (Fig. 3)
(3) Remove the wheel speed sensor from the hub.
(4) Remove the wiring from the clips and discon-
nect the electrical connector.
INSTALLATION
(1) Install the wiring to the clips and Reconnect
the electrical connector.
(2) Install the wheel speed sensor to the hub.
(3) Install the wheel speed sensor mounting bolt to
the hub. Tighten the bolt to 21 N´m (190 in. lbs.).
(4) Install the front rotor and brake caliper assem-
bly (Refer to 5 - BRAKES/HYDRAULIC/MECHANI-
CAL/ROTORS - INSTALLATION).
REAR WHEEL SPEED SENSOR
DIAGNOSIS AND TESTING - REAR WHEEL
ANTILOCK
Diagnosis of base brake conditions which are
mechanical in nature should be performed first. This
includes brake noise, lack of power assist, parking
brake, or vehicle vibration during normal braking.
The RWAL brake system performs several self-
tests every time the ignition switch is turned on and
the vehicle is driven. The CAB monitors the system
inputs and outputs circuits to verify the system is
operating properly. If the CAB senses a malfunction
in the system it will set a DTC into memory and trig-
ger the warning lamp.NOTE: The MDS or DRB III scan tool is used to
diagnose the RWAL system. For test procedures
refer to the Chassis Diagnostic Manual.
REMOVAL
(1) Raise the vehicle on a hoist.
(2) Remove the brake line mounting nut and
remove the brake line from the sensor stud.
(3) Remove the mounting stud from the sensor and
shield (Fig. 4).
(4) Remove the sensor and shield from the differ-
ential housing.
(5) Disconnect the sensor wire harness and remove
the sensor.
INSTALLATION
(1) Connect the harness to the sensor.Be sure
the seal is securely in place between the sensor
and the wiring connector.
(2) Install the O-ring on the sensor (if removed).
(3) Insert the sensor in the differential housing.
(4) Install the sensor shield.
(5) Install the sensor mounting stud and tighten to
24 N´m (200 in. lbs.).
(6) Install the brake line on the sensor stud and
install the nut.
(7) Lower the vehicle.

STUDS
REMOVAL
(1) Raise and support the vehicle.
(2) Remove the wheel and tire assembly.
(3) Remove the brake caliper, caliper adapter and
rotor, (Refer to 5 - BRAKES/HYDRAULIC/MECHAN-
ICAL/ROTORS - REMOVAL).
(4) Remove the stud from the hub with Remover
C-4150A (Fig. 25).
INSTALLATION
(1) Install the new stud into the hub flange.
(2) Install the three washers onto the stud, then
install the lug nut with the flat side of the nut
against the washers.
(3) Tighten the lug nut until the stud is pulled
into the hub flange. Verify that the stud is properly
seated into the flange.
(4) Remove the lug nut and washers.
(5) Install the brake rotor, caliper adapter, and cal-
iper, (Refer to 5 - BRAKES/HYDRAULIC/MECHAN-
ICAL/ROTORS - INSTALLATION).
(6) Install the wheel and tire assembly, (Refer to
22 - TIRES/WHEELS/WHEELS - STANDARD PRO-
CEDURE), use new the lug nut on stud or studs that
were replaced.
(7) Remove the support and lower vehicle.
WHEEL COVER
REMOVAL
NOTE: The hub caps must be removed before rais-
ing the vehicle off the ground.NOTE: You must use the flat end of the hub/cap
remover/installer combination tool to pry off the
wheel skins. Insert the flat tip completely and using
a back and forth motion, loosen the wheel skin.
repeat this procedure around the tire until the wheel
skin pops off.
(1) On 2500/3500 single rear wheel (SRW) models,
insert a hub/cap remover/installer combination tool
using the blade on the end of the tool to pry the cap
off in a back and forth motion.
(2) On 3500 models with dual rear wheels (DRW),
you must first remove the hub caps. The hub/cap
remover/installer combination tool must be inserted
in the pry off notch of the rear hub caps.
(3) Position the hub/cap remover/installer combina-
tion tool and pull out on the tool firmly. The cap
should come off.
(4) The wheel skins can now be removed from the
wheel.
(5) On 3500 models front hub caps use the hub/cap
remover/installer combination tool to pry off the cap
in a back and forth motion. The wheel skins can now
be removed.
INSTALLATION
INSTALLATION - REAR
(1) Install one 1 1/2 in. valve stem extension on
each rear inner wheel.
NOTE: A 3/8 in. drive 10mm deep wheel socket with
a 10 in. or greater extension can be used to remove
the existing valve stem cap and install the exten-
sion.
(2) Install one 1 in. valve stem extension on each
outer wheel.
(3) Align the cooling windows of the wheel skin
with the cooling windows of the wheel. Seat one side
of the wheel skin's retainer onto the wheel. Using a
rubber mallet, strike thew wheel skin on the outer
circumference. Strike at several locations around the
circumference until the skin is fully seated.
NOTE: The wheel skin and the hub cap are fully
seated when there is a consistent gap between the
skin/cap and the wheel.
(4) Tug on the hub/cap wheel skin to ensure that
they are properly installed.
INSTALLATION - FRONT
(1) Align the valve stem with the notch in the
wheel skin.
