Solution

1. Preparation

Gather Tools: Ensure you have a socket set, torque wrench, jack stands, and OBD-II scanner.
Safety Precautions: Disconnect the battery to prevent any electrical issues while inspecting components.

2. Inspect and Replace Serpentine Belt

Remove the Engine Cover: If applicable, unscrew and remove the engine cover to access the serpentine belt.
Check Belt Condition: Inspect the belt for cracks, fraying, or glazing. If damaged, proceed to replace.
Remove Old Belt: Use a socket wrench to relieve tension from the tensioner pulley, then slide the belt off.
Install New Belt: Route the new belt according to the belt routing diagram and ensure it is properly seated on all pulleys.
Reattach Engine Cover: If removed, secure the engine cover back in place.

3. Inspect and Replace Wheel Bearings (if necessary)

Lift Vehicle: Use a jack to lift the vehicle and secure with jack stands.
Remove Wheel: Take off the wheel to access the hub assembly.
Check for Play: Grasp the hub and check for any lateral movement indicative of a worn bearing.
Replace Bearing: If play is detected, remove the hub assembly, press out the old bearing, and press in a new one.
Reassemble Wheel: Reinstall the wheel and lower the vehicle.

4. Inspect Brake Components

Remove Wheel: As in the previous step, remove the wheel to access the brake assembly.
Check Brake Pads and Rotors: Inspect for wear; replace any pads that are worn down and ensure rotors are not warped.
Reassemble Brake Components: Ensure everything is properly secured and reinstall the wheel.
