Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery if working on the electrical components.

2. Inspect and Replace Brake Components

Brake Pads and Rotors:
1. Remove the wheel using a lug wrench.
2. Inspect the brake pads for thickness; replace if worn below 3mm.
3. Check the rotor surface for grooves or scoring; replace if necessary.
4. Apply brake grease to the back of the pads to reduce noise.
5. Reinstall the wheel and torque to manufacturer specifications.

3. Inspect and Replace Serpentine Belt

Belt and Pulleys:
1. Locate the serpentine belt and inspect for cracks or fraying.
2. If damaged, release tension on the belt using a belt tensioner tool.
3. Remove the old belt and install a new one, following the routing diagram.
4. Check pulleys for smooth operation; replace any that are worn.

4. Inspect and Repair Suspension Components

Suspension:
1. Lift the vehicle and secure it with jack stands.
2. Visually inspect control arms, bushings, and struts for play or damage.
3. Replace any worn bushings or struts as needed.
4. Reassemble all components and lower the vehicle.
