The 2000 Chevy Silverado base model came with a 4.3-liter six-cylinder engine and a five-speed manual transmission. The front wheel speed sensors on your truck are mounted to the steering knuckle and are used to help the computer determine when one wheel is rotating at a different speed than the other. A faulty wheel speed sensor can cause the anti-lock braking system to become inoperative, bring forth the possibility for the front wheels to lock up during hard stops or in slippery conditions. No special tools are required to replace either sensor, but you will have to remove the brake caliper and rotor.
M/F Park the vehicle on a level surface and set the parking brake. Loosen the lug nuts on the wheel to be serviced, using a lug wrench. Lift the front of the truck into the air, using a floor jack, and place jack stands under the front frame rails. Lower the truck until it rests securely on the jack stands.
M/F Remove the lug nuts, and then remove the tire from the truck. Remove the bolts securing the caliper bracket to the steering knuckle, using a socket and ratchet. Remove the caliper and bracket as an assembly and hang it from the suspension with mechanics wire. Slide the brake rotor off of the wheel hub and set it aside.
M/F Remove the wheel speed sensor mounting bolt, using a socket and ratchet. Pull the wheel speed sensor from the wheel hub carefully, using a slight twisting motion if necessary, but do not pry it out of the hub. Follow the sensor pig tail and pry the wire retainers from the steering knuckle, upper control arm and front frame rail, using a pry bar.
M/F Squeeze the plastic locking tab and separate the wheel speed sensor pigtail from the vehicle wiring harness. Remove the wheel speed sensor from under the vehicle.
M/F Compare the new wheel speed sensor to the original to ensure they are the same. Slide the wheel speed connector into the vehicle wiring harness connector, the plastic tab will click into place when properly seated.
M/F Press the plastic retainers for the new harness into the front frame rail hole, upper control arm hole and steering knuckle hole. Press the new wheel speed sensor into the hub assembly, lining up the bolt hole with the hole in the wheel hub. Install the mounting bolt and tighten to 13 foot-pounds, using a torque wrench.
M/F Slide the brake rotor over the wheel studs and onto the wheel hub; be careful not to drag the rotor over the wheel studs. Support the caliper and caliper bracket by hand and remove the mechanics wire. Slide the caliper and bracket into position over the rotor and steering knuckle, lining up the bracket mounting holes with the holes in the steering knuckle. Install the bracket mounting bolts and tighten to 129 foot-pounds.
M/F Install the wheel and tire onto the vehicle and hand tighten the lug nuts. Lift the front of the truck of off the jack stands, using a floor jack, and remove the jack stands from under the truck. Lower the truck to the ground. Tighten the lug nuts to 140 foot-pounds in a crisscross pattern.
M/F Prying on the wheel speed sensor will cause the sensor to break off inside the hub.
