GM 89047669
Rear Speed Sensor

You must lift up the vehicle for this work to begin. Take off the tire and wheel then remove the brake rotor at the back. You should remove the wheel drive shaft nut plus disconnect the abs sensor electrical connector and its backing plate connection. Take out the parking brake cable bracket bolts from the knuckle then detach the parking brake cable bracket. Apply the Wheel Bearing/hub axel remover tool (J 45859 or equivalent) onto the Wheel Bearing/hub to release the driving shaft connection. Use a Wheel Hub remover tool to remove Wheel Bearing/hub bolts because some bearings may need full axial movement before disengagement from the drive axle. Lift out the Wheel Bearing/hub and backing plate from the knuckle while also taking away the axle remover (J 45859) or comparable tool. Position the Wheel Bearing/hub along with the backing plate onto the knuckle and put in the bolts afterwards. Tighten the bolts to 125 n.m (92 lb ft). Secure the parking brake cable bracket to its location and bolt down all components at 60 n.m (44 lb ft). Plug the abs sensor electrical connector to the backing plate and main connector. Fasten the new wheel drive shaft nut to 160 n.m tension before installing the brake rotor and tire assembly. Finally, lower the vehicle.

Start the rear wheel bearing/hub replacement by lifting the vehicle before supporting it and moving on to tire removal followed by wheel removal and finally the rear brake rotor removal process. First remove the wheel drive shaft nut along with the abs sensor electrical connector and the backing plate connector. Use a wrench to remove the mounting bolts from the parking brake cable bracket on the knuckle before removing the parking brake cable bracket. Disengage the wheel drive shaft from the wheel bearing/hub using the axle remover (J 45859) before removing its mounting bolts to extract the wheel bearing/hub and backing plate assembly from the knuckle. Use the Wheel Hub remover as needed to fully free the wheel bearing/hub from the drive axle before removing the axle remover (J 45859) from its position on the bearing/hub. Mount the wheel bearing/hub and backing plate again on the knuckle before tightening the mounting bolts to 125 nm (92 ft. Lbs.). Make sure to install the parking brake cable bracket while tightening its mounting bolts to 60 nm (44 ft. Lbs.). Attach the abs sensor electrical connector to the backing plate before moving it toward the main connector. Install a new wheel drive shaft nut, tightening it to 160 nm (118 ft. Lbs.)the process involves installing the wheel drive shaft nut first and then the brake rotor before adding the tire and wheel. After that lower the car.

Remove the tire and wheel, followed by the brake rotor.

Remove the parking brake cable bracket mounting bolts from the knuckle and take off the parking brake cable bracket.

Install a new wheel drive shaft nut, tightening it to 160 Nm (118 ft. lbs.).

Reconnect the ABS electrical connector, reinstall the brake rotor, put the tire and wheel back on, and lower the vehicle.

Raise and support the vehicle.

Disconnect the ABS electrical connector and the electrical connector from the splash shield.
