  Q: How do I remove and install a front hub/bearing assembly on Chevrolet Impala and Monte Carlo?

  A: To remove the hub/bearing assembly, start by loosening the wheel lug nuts and raising the front of the vehicle on jackstands. Remove the wheel and disconnect the ABS wheel speed sensor electrical connector, if applicable. Take off the driveaxle/hub nut and then remove the brake caliper, caliper mounting bracket, and brake disc from the hub. Next, remove the hub/bearing assembly mounting bolts from the back of the Steering Knuckle and discard them. Finally, remove the hub/bearing assembly from the steering knuckle. To install the hub/bearing assembly, ensure that the mounting surfaces are smooth and free of any damage. Lubricate the driveaxle splines with multi-purpose grease and then fully seat the hub/bearing assembly onto the steering knuckle. Use new mounting bolts to secure the assembly to the knuckle, tightening them to the correct torque specifications. For ABS-equipped vehicles, connect the wheel speed sensor harness connector and secure it to its bracket. Install the brake disc, caliper mounting bracket, and caliper, tightening the fasteners to the proper torque values. Install the driveaxle/hub nut and tighten it to the correct torque specifications. Finally, install the wheel and lug nuts, remove the jackstands, and lower the vehicle. Tighten the lug nuts to the proper torque specifications.
