GM 13546785 HUB ASM-RR WHL

Driveaxle/hub nut loosening should be your first step when servicing models from 2007 and later. Next, remove the wheel lug nuts before vehicle raising using jackstands for secure wheel removal. The first step involves eliminating the brake disc followed by disconnecting the wheel speed sensor electrical connector then unclipping the harness from its bracket. After the second loosening of the driveaxle/hub nut you must use wire to support the driveaxle while preventing it from hanging at the inner CV joint after removing the hub and bearing. The hub mounting bolts require removal alongside hole cleaning before new high-strength thread-locking compound should be used when reinstalling. Application of hammer blows with wood blocks on the driveaxle end requires removal of the hub and bearing unit when encountered with sticking. Reversing the removal series will enable installation of the components through proper torque bolt tightening.

Raise and support the vehicle, remove the wheels, then unbolt the sway bar, control arms, and struts as needed.

Start by loosening the rear wheel lug nuts and blocking the front wheels.

For 2007 or earlier models, disconnect the wheel speed sensor electrical connector and free the harness from any retaining clips. For 2008 or later models, remove the wheel speed sensor from the knuckle.

For 2008 or later models, remove the wheel speed sensor from the steering knuckle.

Take out the three hub mounting bolts from the backside of the steering knuckle and remove the hub and bearing assembly from the knuckle.

Ensure that the mounting surface inside the steering knuckle and the driveaxle splines are smooth and free of burrs and nicks. Lubricate the driveaxle splines with multi-purpose grease and fully seat the hub and bearing assembly into the steering knuckle.

Start by loosening the rear wheel lug nuts and, on AWD models, the rear driveaxle/hub nut.

Start by loosening the rear drive-axle/hub nut on AWD models. Then, loosen the wheel lug nuts, raise the vehicle, and support it securely on jackstands. Remove the wheel and the brake drum or disc. On AWD models, remove the driveaxle/hub nut and use wire to support the end of the driveaxle. Disconnect the electrical connector for the wheel speed sensor. Remove the hub mounting bolts and guide the hub and bearing out.
