INSTALLATION

CAUTION: Failure to install speed sensor cables
properly may result in contact with moving parts or
an over extension of cables causing an open cir-
cuit. Be sure that cables are installed, routed, and
clipped properly.
(1) Install the wheel speed sensor head into the
disc brake adapter (Fig. 12).
(2) Install the wheel speed sensor mounting bolt.
Tighten the mounting bolt to a torque of 12 N·m (105
in. lbs.).
(3) Install wheel speed sensor cable into the rout-
ing clips on the brake tube, brake hose and axle
trailing arm.
(4) Connect the wheel speed sensor cable connector
into vehicle wiring harness (Fig. 11). Install the clip
attaching the wheel speed sensor cable connector to
vehicle's body.
(5) Install the tire and wheel assembly on vehicle.
Progressively tighten wheel mounting nuts to 135
N·m (100 ft. lbs.).
(6) Lower the vehicle.
(7) Road test the vehicle to ensure proper opera-
tion of the base brakes and ABS.
TONE WHEEL
DESCRIPTION
The tone wheel is used in conjunction with the
wheel speed sensors. (Refer to 5 - BRAKES - ABS/
ELECTRICAL/FRONT WHEEL SPEED SENSOR -
DESCRIPTION) or (Refer to 5 - BRAKES - ABS/
ELECTRICAL/REAR WHEEL SPEED SENSOR -
DESCRIPTION)

OPERATION

The tone wheel is used in conjunction with the
wheel speed sensors. (Refer to 5 - BRAKES - ABS/
ELECTRICAL/FRONT WHEEL SPEED SENSOR -
OPERATION) or (Refer to 5 - BRAKES - ABS/ELEC-
TRICAL/REAR WHEEL SPEED SENSOR - OPERA-
TION)

INSPECTION

Tone wheels can cause erratic wheel speed sensor
signals. Inspect tone wheels for the following possible
causes:
• missing, chipped, or broken teeth
• contact with the wheel speed sensor
• wheel speed sensor to tone wheel alignment
• wheel speed sensor to tone wheel clearance
• excessive tone wheel runout
• tone wheel loose on its mounting surface
If a front tone wheel is found to need replacement,
the drive shaft must be replaced. No attempt should
be made to replace just the tone wheel. (Refer to 3 -
DIFFERENTIAL & DRIVELINE/HALF SHAFT -
REMOVAL).
If a rear tone wheel is found to need replacement,
the rear hub and bearing must be replaced. No
attempt should be made to replace just the tone
wheel. (Refer to 2 - SUSPENSION/REAR/HUB /
BEARING - REMOVAL).
