  Q: How to replace the wheel hub and speed sensor on Chevrolet Colorado?

  A:

  When replacing the Wheel Hub and speed sensor start by lifting the car and disconnect the wheel drive shaft nut if it exists. Before handling the Wheel Hub and speed sensor, you must disconnect both front brake caliper parts from the upper Control Arm and both connections of the abs sensors wiring harness. Next separate the front retaining bolt from the speed sensor bracket. To install the speed sensor bracket correctly note the connector positions on the current part before you remove it. Nest the speed sensor body connector and paint the speed sensor's wiring harness attachment point to the Steering Knuckle with white paint. Remove the wheel bearing/hub and brake rotor mounting bolts before taking out the wheel bearing/hub assembly from the knuckle with the brake rotor placed on a flat surface. Wipe clean the surface where the wheel bearing/hub connects with the brake rotor. The single mounting bolt securing these parts needs to be removed for cleaning. When needed, install a new Wheel Speed Sensor on the hub before placing the bearing hub against the rotor and securing it with 20 nm (15 lb ft) torque using a crisscross pattern. Place the backing plate over the wheel bearing hub and brake assembly as you position the wheel bearing hub into the Steering Knuckle while maintaining alignment of the Wheel Speed Sensor wiring harness with its reference point on the Steering Knuckle. Secure the wheel bearing/hub with its brake rotor by tightening the mounting bolts to 125 nm (92 lb ft), then connect the brake caliper mounting bracket. Apply force on a screwdriver across the cooling fins of the brake rotor while pushing the brake rotor securing bracket with a pry bar to tighten all the mounting bolts for 110 nm (81 lb ft) torque in serial order. Put on the wheel drive shaft nut then fasten it to 260 nm (191 lb ft). Attach the speed sensor wiring harness bracket and front bolt before locking it to 20 nm force. Hook the wiring harness retainers onto the upper Control Arm. Link the Wheel Speed Sensor electrical connector to the body and reposition your car.

  Q: How to service the wheel hub and speed sensor on Chevrolet Colorado?

  A:

  Caution: service the Wheel Hub and speed sensor only after raising the vehicle. Begin by removing the wheel drive shaft nut if present then remove the front Brake Caliper Bracket. Disconnect the antilock brake system (ABS) speed sensor wiring harness from the upper Control Arm then detach and remove its front retaining bolt from the speed sensor bracket on the upper Control Arm before finally extracting the speed sensor bracket. Place marks on the holes where the speed sensor electric connector is mounted to aid future installation. First disconnect your body from the speed sensor electrical connector then tag the speed sensor wiring harness position on the Steering Knuckle with white or bright colored paint. Start by taking off the mounting bolts securing the wheel bearing/hub and brake rotor assembly before removing the wheel bearing/hub assembly from the knuckle. Use a clean flat surface to remove wheel bearing/hub to brake rotor mounting bolts and then clean the entire bolt contact zone. Begin with sensor installation at the bearing hub position before placing the wheel bearing/hub assembly onto the brake rotor for correct mounting bolt installation. Follow a crisscross bolt tightening pattern when applying torque to 20 nm (15 lb ft) before placing the backing plate between the wheel bearing/hub and brake rotor assembly. Guide the Wheel Speed Sensor wiring harness along its reference mark on the Steering Knuckle before installing the hub bearing to the knuckle with tightening bolts set to 125 nm (92 lb ft). Place a big screwdriver in the brake caliper mounting bracket's cooling fins before tightening each brake rotor bolt in sequence to 110 nm (81 lb ft). Start by installing the wheel drive shaft nut before placing the Wheel Speed Sensor wiring harness bracket onto the upper Control Arm. Then apply 20 nm torque (14 lb ft) to the front retaining bolt for the speed sensor wiring harness. Complete the installation by placing speed sensor wiring harness retainers onto the upper Control Arm then reconnect the Wheel Speed Sensor electrical connector to the body and incrementally lower the vehicle.
