Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and engage the parking brake.
Disconnect the battery if necessary for safety.

2. Inspect and Replace Suspension Components

Sub-steps:
- Remove the wheel to access the suspension components.
- Use a socket set to remove bolts securing the struts and control arms.
- Inspect bushings and ball joints for wear.
- Replace any damaged parts with new OEM or high-quality aftermarket components.
- Torque bolts to manufacturer specifications (refer to service manual for specific torque values).

3. Examine and Repair Exhaust System

Sub-steps:
- Inspect exhaust hangers and brackets for damage or wear; replace as needed.
- Check for any cracks or holes in the exhaust pipes or muffler.
- If damage is found, cut out the damaged section and weld in a new piece or replace the exhaust component completely.

4. CV Joint and Boot Service
