(1) Install wheel speed sensor head in steering
knuckle and install mounting bolt (Fig. 2). Tighten
mounting bolt to 11 N·m (100 in. lbs.) torque.
(2) Route sensor harness along brake flex hose and
install it in routing clips.
(3) Push sensor connector fastener clip into mount-
ing hole in frame rail.
(4) Connect vehicle wiring harness to sensor con-
nector.
(5) Install tire and wheel assembly (Refer to 22 -
TIRES/WHEELS - INSTALLATION). Progressively
tighten the wheel mounting nuts in the proper
sequence to 122 N·m (90 ft. lbs.) torque.
(6) Lower the vehicle.
(7) Road test vehicle to ensure proper operation of

REMOVAL
NOTE: Before proceeding, review Warnings and
Cautions. (Refer to 5 - BRAKES - WARNING) (Refer
to 5 - BRAKES - CAUTION)
(1) Raise vehicle. (Refer to LUBRICATION &
MAINTENANCE/HOISTING - STANDARD PROCE-
DURE).
(2) Remove wheel and tire assembly. (Refer to 22 -
TIRES/WHEELS - REMOVAL)
(3) Disconnect vehicle wiring harness from wheel
speed sensor wiring connector at frame rail.
(4) Remove fastener clip securing sensor connector
to frame rail.
(5) Open routing clips along parking brake cable
and remove sensor harness.
(6) Remove bolt fastening sensor head to knuckle
(Fig. 3).
CAUTION: When removing a wheel speed sensor
from the knuckle, do not use pliers on the sensor
head. This may damage the sensor head. If the sen-
sor has seized, use a hammer and a punch to tap
the edge of the sensor head ear, rocking the sensor
side-to-side until free.
(7) Carefully remove sensor head from knuckle.
INSTALLATION
CAUTION: Failure to install speed sensor properly
may result in contact with moving parts or an over
extension of wires causing an open circuit. Be sure
that sensor harnesses are installed, routed, and
clipped properly.
(1) Install wheel speed sensor head in knuckle and
install mounting bolt (Fig. 3). Tighten mounting bolt
11 N·m (100 in. lbs.) torque.
(2) Route sensor harness along parking brake
cable and install routing clips. Close clips.
