5 - 104 ANTI-LOCK 10 BRAKE SYSTEM
REAR WHEEL SPEED SENSOR (FIGS. 13 AND 15)
REMOVAL
(1)Raise vehicle and remove wheel and tire assem-
bly.
(2)Remove sensor assembly grommet from underbody and pull harness through hole in underbody.
(3)Unplug connector from harness.
(4)Remove sensor grommet bracket screw from body hose bracket, just forward of trailing arm bushing.
(5)Remove sensor assembly clip, located on the inboard side of trailing arm.
(6)Remove sensor wire fastener from rear brake hose bracket.
(7)Remove outboard sensor assembly retainer nut.
(8)Remove sensor head screw.
(9)Carefully, remove sensor head from adapter assembly. If the sensor has seized, due to corrosion, DO NOT USE PLIERS ON SENSOR HEAD. Use a hammer and a punch (Fig. 14) and tap edge of sensor ear, rocking the sensor side to side until free.
INSTALLATION
Installation is reverse order of removal. Be sure to coat sensor with High Temperature Multi-purpose E.P. Grease before installing into adapter assembly.
Ä
Tighten screw to 7 NIm (60 in. lbs.) torque. Avoid getting grease on the pickup area of the speed sensor assembly.

GENERAL INFORMATION
The purpose of the Anti-Lock Brake System (ABS) is to prevent wheel lock-up under heavy braking conditions on virtually any type of road surface. AntiLock Braking is desirable because a vehicle which is stopped without locking the wheels will retain directional stability and some steering capability. This allows the driver to retain greater control of the vehicle during heavy braking.
