Step-by-Step Guide to Replacing Front Wheel Bearings

Safety First: Park your Impala on a level surface, engage the parking brake, and secure the wheels with chocks.
Remove the Lug Nuts: Using a lug wrench, loosen but do not remove the lug nuts on the affected wheel.
Jack Up the Vehicle: Position a jack under the designated jack point near the affected wheel and carefully raise the vehicle until there's approximately 6 inches of clearance.
Remove the Wheel: Completely remove the lug nuts and pull the wheel straight towards you to detach it from the hub assembly.
Detach the Caliper: Unbolt and remove the brake caliper, then secure it out of the way without straining the brake hose.
Extract the Rotor: Slide the rotor off the hub assembly. If it's stuck, gently tap it with a hammer to loosen it.
Remove the Hub Nut: Use a socket wrench to remove the large hub nut that secures the hub assembly to the spindle.
Separate the Hub Assembly: Use a ball joint separator or pickle fork to carefully pry the hub assembly loose from the spindle.
Replace the Bearing: Inspect the old bearing for signs of damage or wear. Press the new bearing into the hub assembly using a bearing press or a properly sized socket and hammer.
Reassemble the Components: Reinstall the hub assembly onto the spindle, tighten the hub nut, and reattach the rotor.
Mount the Caliper: Secure the brake caliper back onto the hub assembly and tighten the bolts.
Install the Wheel: Align the wheel with the hub assembly and slide it into place. Tighten the lug nuts by hand, then fully tighten them using a torque wrench to the manufacturer's specifications.
Lower the Vehicle: Carefully lower the vehicle by releasing the jack.
Final Touches: Double-check that all bolts and nuts are properly tightened, and torque them if necessary. Test drive your Impala to ensure smooth operation and absence of any unusual noises or vibrations.
