Solution

1. Preparation

Gather tools and parts required for repairs.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the battery for safety.

2. Inspect and Replace Serpentine Belt (if necessary)

Remove the engine cover if equipped.
Use a socket wrench to relieve tension on the serpentine belt tensioner.
Remove the serpentine belt from the pulleys.
Inspect the belt for cracks, fraying, or glazing; replace if damaged.
Route the new belt according to the belt routing diagram located on the engine.
Reapply tension using the tensioner and ensure proper installation.

3. Check and Replace Brake Components (if necessary)

Remove the wheel to access the brake assembly.
Inspect brake pads for wear; replace if the friction material is below specifications (generally below 3mm).
Check the brake rotor surface for grooves or scoring; replace if necessary.
Reassemble the brake components and wheel.

4. Inspect Wheel Bearings (if necessary)

Elevate the vehicle and remove the wheel.
Spin the wheel hub to check for roughness or play indicating bearing wear.
If bearings are worn, remove the hub assembly per manufacturer specifications.
Replace the wheel bearings and reassemble the hub and wheel.

5. Inspect and Replace Pulleys (if necessary)

Visually inspect all pulleys for signs of damage or misalignment.
If a pulley is damaged, remove the relevant components to access the pulley.
Replace the faulty pulley and reassemble the components.
