Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Gather safety equipment (gloves, safety glasses).

2. Inspect and Replace Brake Components

Sub-steps:
1. Remove the wheel using a socket set.
2. Inspect the brake pads for thickness (replace if less than 3mm) and check the rotors for scoring.
3. If worn, replace brake pads:
  - Remove caliper bolts using a socket wrench.
  - Slide off the caliper and replace pads.
  - Reattach caliper and torque bolts to manufacturer's specifications (typically 25-30 lb-ft).
4. Reinstall the wheel and torque lug nuts to specifications (typically 76 lb-ft).

3. Inspect and Replace Suspension Components

Sub-steps:
1. Visually inspect all suspension components for cracks or excessive wear.
2. If bushings are cracked or worn, replace them:
  - Remove the affected component (e.g., control arm) using a socket set.
  - Press out worn bushings using a hydraulic press.
  - Install new bushings and reassemble the components.
3. For struts or shocks, if worn, replace them:
  - Remove the strut assembly by loosening bolts.
  - Replace with new strut and reassemble, ensuring to torque bolts to specifications.

4. Inspect and Replace Serpentine Belt

Sub-steps:
1. Locate the serpentine belt and inspect for cracks or fraying.
2. If damaged, relieve tension on the belt using a belt tensioner tool.
3. Remove the old belt and install a new one, ensuring it follows the correct routing.
4. Check the pulleys for alignment and wear before reapplying tension.
