GM 25954415 Rear Wheel Bearing (W/ Bearing)

Loosen the wheel lug nuts and drive axle/hub nut, then raise the vehicle and support it securely on jackstands before removing the wheel. Unbolt and set aside the caliper and caliper mounting bracket, ensuring the caliper does not hang by the brake hose; instead, wire it to the spring or shock absorber with mechanic's wire. Remove the brake disc, followed by the drive axle/hub nut. 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. Remove the three hub mounting bolts from the back side of the rear knuckle, noting that it may be necessary to push the outer end of the drive axle into the hub to allow for bolt removal. Next, remove the hub nut and slide the hub and bearing assembly from the rear knuckle, using a two-or three-jaw puller if the drive axle splines stick in the hub splines. Installation is the reverse of removal, ensuring to tighten the fasteners to the proper torque specifications, use a new drive axle/hub nut, and tighten it accordingly. Finally, tighten the brake component fasteners to the specified torque, install the wheel and lug nuts, lower the vehicle, and tighten the lug nuts to the required torque.

To remove the wheel, loosen the wheel lug nuts, then lift the car and resting it on jack stands firmly before removing the wheel. After that, unbolt the brake disc, then the drive axle/hub nut if it is applicable to your vehicle model. Remove the ABS wheel speed sensor from the knuckle and take out the three hub mounting bolts from the rear side of the rear knuckle where it might be required to perform a slight push on the outer end of the drive axle to be able to remove the bolts. Remove the hub and bearing assembly to afford room at the rear knuckle; in cases where the splines of the drive axle mesh with those of the hub you would need to use a two or three-jaw puller and push the drive axle off the hub because the latter is being slid off the knuckle. For removal, reverse the installation process as follows: mount the brake components, tighten the mounting bolts to the relevant torque, replace the drive axle/hub nut and tighten the new nut to the right torque, tighten the brake component fasteners to the relevant torque figures, install the wheel and the lug nuts, lower the vehicle, and finally, tighten the lug nuts to the recommended torque.

The hub and wheel bearing are press-fit together and removed as an assembly, which can be taken to an automotive repair facility for service.

Lower the vehicle and tighten the nuts to the specified torque.
