Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and securely lifted with jack stands.
Disconnect the battery (if working on electrical components).

2. Inspect and Replace Brake Components

Remove Wheel
- Use a lug wrench to loosen the lug nuts.
- Jack up the vehicle and remove the wheel.
Inspect Brake Pads and Rotors
- Check the thickness of the brake pads; replace if below 3mm.
- Inspect rotors for grooves or scoring; replace if necessary.
Install New Brake Pads or Rotors
- Remove the caliper bracket bolts and slide off the caliper.
- Replace pads and or rotors and reassemble caliper with proper torque (usually 25-35 ft-lbs).

3. Check and Replace Serpentine Belt

Locate Serpentine Belt
- Identify the belt routing diagram (usually on a sticker under the hood).
Remove Belt
- Use a wrench to relieve tension on the tensioner pulley and slide the belt off.
Install New Serpentine Belt
- Route the new belt according to the diagram and ensure it is properly seated on all pulleys.

4. Inspect Suspension Components

Check for Wear
- Visually inspect control arms, bushings, and struts for deterioration or damage.
Replace Damaged Components
- If any components are worn, remove and replace with new parts, ensuring all bolts are torqued to manufacturer specifications.
