Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Safely lift the vehicle using a hydraulic jack and secure it with jack stands.

2. Inspect and Replace Suspension Components

Visual Inspection:
- Examine the shocks and struts for leaks or physical damage.
- Inspect control arms and bushings for cracks or deterioration.
- Check sway bar links for looseness or wear.
Replace Worn Components:
- If any part is found to be defective:
  - Remove the wheel for easier access.
  - Disconnect sway bar links using a socket set.
  - Unbolt the strut from the top mount and lower control arm.
  - Replace with new shocks/struts or sway bar links as necessary.
  - Reassemble components in reverse order and torque bolts to manufacturer specifications.

3. Exhaust System Inspection

Inspect exhaust hangers and brackets for tightness.
Replace any broken or loose hangers to eliminate rattling noise.
