Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and secure it with wheel chocks.
Wear safety glasses and gloves.

2. Inspect and Replace Brake Components

Remove Wheel:
- Use a jack to lift the vehicle and securely place jack stands.
- Remove the lug nuts with a socket set and take off the wheel.
Inspect Brake Pads and Rotors:
- Check for wear on brake pads (less than 1/8 inch remaining indicates replacement).
- Inspect rotors for grooves or excessive wear.
Replace Components:
- If pads are worn, remove the caliper and replace the pads with new OEM parts.
- Resurface or replace rotors if necessary.
Reassemble:
- Reinstall the caliper and wheel.
- Torque lug nuts to manufacturer specifications (typically 80-100 ft-lbs).

3. Inspect and Replace Serpentine Belt

Access Belt:
- Remove any components obstructing access to the serpentine belt, if necessary.
Inspect Belt:
- Check for cracks, fraying, or signs of wear.
Replace Belt:
- Release tension on the belt tensioner using a socket wrench.
- Remove the old belt and install a new one according to the routing diagram typically located on the engine bay.
Test:
- Start the engine and listen for any changes in noise.

4. Check Wheel Bearings

Lift Vehicle:
- Raise the vehicle and secure it on jack stands.
Inspect Bearings:
- Grab the wheel at the 12 and 6 o'clock positions and shake to check for play.
- If excessive play is felt, the bearings may need replacing.
Replace Bearings:
- Remove the wheel and brake components as necessary to access the hub assembly.
- Replace the wheel bearings with new OEM parts and reassemble.
