Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Wear safety glasses and gloves.

2. Raise the Vehicle

Use a hydraulic jack to lift the front of the vehicle.
Secure it with jack stands to prevent accidental lowering.

3. Remove the Wheel

Use a socket set to remove the lug nuts and take off the front wheel.
Inspect the brake caliper and rotor for any visible damage.

4. Inspect and Replace Components

Brake Pads and Rotors:
- Remove the caliper bolts and lift the caliper away from the rotor.
- Inspect brake pads for thickness and replace if worn.
- Check the rotor for scoring or warping; replace if necessary.
Wheel Bearings:
- Remove the wheel hub assembly as per manufacturer specifications.
- Inspect wheel bearings for excessive play or wear.
- Replace with new bearings if defects are found.

5. Reassemble

Reinstall the wheel hub and torque to manufacturer specifications.
Reattach the brake caliper and ensure all bolts are tightened properly.
Place the wheel back on and hand-tighten the lug nuts.

6. Lower the Vehicle

Carefully remove jack stands and lower the vehicle back to the ground.
Torque the lug nuts to specification in a star pattern.
