Solution

1. Preparation

Gather tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Ensure the engine is turned off and cool before starting work.

2. Inspect and Replace Brake Components

Remove the Wheel:
- Use a jack to lift the vehicle and secure it on jack stands.
- Remove the lug nuts with a socket set and take off the wheel.
Assess Brake Pads and Rotors:
- Inspect brake pads for thickness and uneven wear.
- Check rotors for scoring or warping.
- If replacement is necessary, proceed to replace pads and/or rotors.
Install New Brake Pads/Rotor:
- If replacing, apply brake grease to the contact points.
- Mount new pads and/or rotors, ensuring proper alignment.
- Torque the lug nuts to the manufacturer's specification.

3. Check and Replace Serpentine Belt

Locate the Serpentine Belt:
- Identify the belt routing diagram, typically found on a sticker under the hood.
Remove the Belt:
- Use a wrench to relieve tension from the tensioner pulley.
- Slide the belt off the pulleys and inspect for damage.
Install New Belt:
- Route the new belt according to the diagram.
- Ensure it correctly fits all pulleys and reapply tension.

4. Examine Suspension Components

Visual Inspection:
- Check for any visible cracks or wear on suspension bushings and mounts.
- Inspect struts and shocks for leaks.
Replace Worn Components:
- If wear is noted, remove the affected components.
- Install new bushings, struts, or shocks as necessary, following torque specifications.
