1. Remove the brake caliper and rotor to expose the wheel bearings.
2. Inspect the wheel bearings for excessive play or noise by turning them by hand.
3. If damaged, remove the old bearings using a bearing puller.
4. Clean the hub assembly and install new bearings, ensuring they are properly seated.
5. Reassemble the rotor and caliper, torquing bolts to manufacturer specifications.

3. Check and Replace Brake Components

Sub-steps:
1. Inspect brake pads for uneven wear; replace if worn beyond the manufacturer's limit.
2. Check brake rotors for warping or scoring; replace if necessary.
3. Reinstall the brake caliper after replacing components, ensuring proper torque settings.

4. Inspect and Replace Serpentine Belt

Sub-steps:
1. Check the serpentine belt for cracks or fraying.
2. If damaged, remove the tensioner using an appropriate socket and replace the belt.
3. Ensure the new belt is routed correctly through all pulleys and check for proper tension.
