FRONT WHEEL SPEED SENSOR (REMOVE)
(1) Raise vehicle and remove front wheel and tire
assembly.
(2) Remove screw from clip (Fig. 5) that holds sensor
assembly grommet into fender shield.
(3) Carefully, pull sensor assembly grommet from
fender shield. When removing grommet from
fender shield, do not pull on speed sensor cable.
(4) Unplug speed sensor cable connector, from ve-
hicle wiring harness.
(5) Remove the 2 screws (Fig. 5) that secure the
speed sensor cable, routing tube to the fender well.
(6) Remove the 2 sensor assembly grommets from
the retainer bracket, on the strut damper (Fig. 5).
(7) Remove speed sensor assembly to steering
knuckle attaching bolt (Fig 6).
(8) Carefully, remove sensor head from steering
knuckle. If the sensor has seized, due to corrosion, use
a hammer and punch to tap edge of sensor ear (Fig. 6),
rocking the sensor side to side until free. DO NOT
USE PLIERS ON SENSOR HEAD.
INSTALL
(1) Connect the wheel speed sensor cable connector,
to the vehicle wiring harness.
(2) Push sensor assembly grommet into hole in
fender shield. Install clip and screw (Fig 6). Torque
screw to 4 N
Im (35 in. lbs.).
(3) Install speed sensor cable grommets in bracket
on strut damper (Fig. 5).
(4) Install speed sensor cable routing tube to fender
well (Fig. 5). Torque both screws to 4 N
Im (35 in. lbs.).
(5) Coat the speed sensor with High Temperature
Multi-purpose E.P. Grease before installing into the
steering knuckle. Install speed sensor attaching screw
and tighten to 7 N
Im (60 in. lbs.)
CAUTION: Proper installation of wheel speed sensor
cables is critical to continued system operation. Be
sure that cables are routed correctly and installed in
all retainers. Failure to properly route and install
cables in retainers, as shown in this section. May
result in contact with moving parts and/or over ex-
tension of cables, resulting in an open circuit.

REAR WHEEL SPEED SENSOR
REMOVAL FRONT WHEEL DRIVE
(1) Raise vehicle and remove rear wheel and tire
assembly.
(2) Remove rear speed sensor wiring grommet re-
taining bracket. Remove grommet from underbody and
pull harness through hole in underbody. (Fig. 7) When
removing grommet from underbody, do not pull
on speed sensor cable.
(3) Unplug speed sensor cable connector, from ve-
hicle wiring harness.
(4) Remove the 4 arrow head clips which route the
speed sensor wiring along the underbody (Fig. 7).
(5) Remove the wiring to frame rail attaching
bracket (Fig. 7).
(6) Loosen and remove the rear axle U-bolt nuts,
which retain the rear speed sensor cable assembly
mounting bracket. Remove the bracket from the ve-
hicle.
(7) Remove speed sensor head to rear brake support
plate, attaching bolt (Fig. 8).
(9) Carefully, remove sensor head from rear brake
support plate assembly. If the sensor has seized, due to
corrosion. Use a hammer and punch (Fig. 6) to tap edge
of sensor ear, rocking the sensor side to side until free.
DO NOT USE PLIERS TO TRY TO REMOVE
SENSOR HEAD.
INSTALL FRONT WHEEL DRIVE.
(1) Position the rear speed sensor cable and bracket
assembly on the rear axle U-bolt (Fig. 7). Install the
rear axle U-bolt nuts and tighten to 88 N
Im (65 ft. lbs.)
torque.
(2) Coat the speed sensor head with High Tempera-
ture Multi-Purpose E.P. Grease. Install the speed sen-
sor head into rear brake support plate. On the driver
side the speed sensor wire is routed between the brake
tube and the wheel brake. Torque the speed sensor to
rear brake support plate attaching bolt (Fig. 8) to 7
N
Im (60 in.lbs.)
(3) Bend the speed sensor cable assembly, rubber
coated section toward the front of the vehicle. Position
the anti-rotation tab of the sensor assembly frame rail
bracket into its respective hole. Install the screw that
attaches the frame rail bracket to the frame and torque
to 4 N
Im (35 in. lbs).
(4) Connect the speed sensor cable assembly to the
vehicle rear wiring harness. Install the speed sensor
cable assembly grommet (Fig. 5) back into the under-
body wiring access hole.
(5) Position the rear sensor assembly grommet re-
taining bracket back on the underbody, (Fig. 7) making
sure the bracket does not pinch the sensor wiring.
Install the 2 bracket mounting screws and torque to 4
N
Im (35 in.lbs.).
(6) Route the speed sensor wiring along the vehicle
frame rail (Fig. 7) and install the 4 arrow head clips.
(7) Install the rear wheel assembly and torque the
wheel stud nuts to 129 N
Im (95 ft.lbs.)

REMOVE ALL WHEEL DRIVE
(1) Raise vehicle and remove rear wheel and tire
assembly.
(2) Remove rear speed sensor wiring grommet, re-
taining bracket. Remove grommet from underbody and
pull harness through hole in underbody. (Fig. 9) When
removing grommet from underbody, do not pull
on speed sensor cable.
(3) Unplug speed sensor cable connector, from ve-
hicle wiring harness.
(4) Remove the 4 arrow head clips which route the
speed sensor cable along the underbody (Fig. 9).
(5) Remove the speed sensor cable and its frame rail
routing bracket as an assembly. (Fig. 9).
(6) Remove the 2 bolts which secure the speed sensor
cable assembly mounting bracket to the rear axle.
Remove the bracket assembly from the vehicle by
rotating the bracket and removing it from under the
brake tube.
(7) Remove the speed sensor assembly attaching bolt
(Fig. 10).
(9) Carefully, remove sensor head from rear axle
assembly casting. If the sensor has seized, due to
corrosion. Use a hammer and punch (Fig. 6) to tap edge
of sensor ear, rocking the sensor side to side until free.
DO NOT USE PLIERS TO TRY TO REMOVE THE
SPEED SENSOR HEAD.
INSTALL ALL WHEEL DRIVE.
(1) Position the rear wheel speed sensor assembly
bracket under the brake tube (Fig. 9). Hand start the
outboard bracket attaching bolt. Align the brake tube
clip and sensor assembly bracket and secure with bolt.
Torque both bolts to 17 N
Im (145 in. lbs.)
(2) Coat the wheel speed sensor head with High
Temperature Multi-Purpose E.P. Grease. Install the
wheel speed sensor head into the rear axle casting (Fig.
10) and install bolt. Torque the speed sensor to rear
axle attaching bolt to 7 N
I (60 in.lbs.)
(3) Bend the speed sensor cable assembly, rubber
coated section toward the rear of the vehicle. Position
the anti-rotation tab of the sensor assembly frame rail
bracket, into its respective hole. Install the screw that
attaches the frame rail bracket to the frame and torque
to 4 N
Im (35 in. lbs).
(4) Connect the speed sensor cable assembly to the
vehicle rear wiring harness. Install the speed sensor
cable assembly wiring grommet (Fig. 9) back into the
underbody wiring access hole.
(5) Position the rear speed sensor cable assembly
grommet retaining bracket on the underbody, (Fig. 9)
making sure the bracket does not pinch the sensor
wiring. Install the 2 bracket mounting screws and
torque to 4 N
Im (35 in.lbs.).
(6) Route the speed sensor wiring along the vehicle
frame rail (Fig. 9) and install the 4 arrow head clips.
(7) Install the rear wheel assembly and torque the
