    Before starting the Wheel Bearing and hub replacement job you need to lift and support the vehicle. Check off the tire then wheel followed by detaching the brake rotor. Detach the electrical connector for the Wheel Bearing/hub unit. Use a socket wrench to remove the Wheel Bearing/hub retaining bolts, then slide out the Wheel Bearing/hub lower part together with the brake shield from the lower Control Arm. Before adding the hub and bearing you should clean both sides of the Control Arm and the inner retaining cavity. Place the brake shield and Wheel Bearing/hub unit onto the Control Arm while ensuring to torque Wheel Bearing/hub bolts to 68 n.m (50 lb ft). Connect the wheel electrical plug first then install the brake rotor piece followed by putting back the wheel and tire then lowering the vehicle.
