Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a flat surface, engage the parking brake, and ensure it is safely supported on jack stands.
Wear safety goggles and gloves for protection.

2. Inspect Suspension Components

Sub-steps:
- Use a socket set to remove the wheel lug nuts and take off the front wheels.
- Visually inspect shock absorbers, struts, and control arms for any visible damage or wear.
- Check for loose bolts and tighten them to the manufacturer's specifications.

3. Examine Exhaust Components

Sub-steps:
- Inspect the exhaust system for looseness or damage, particularly around the hangers and joints.
- Tighten any loose clamps and replace damaged sections of the exhaust if necessary.

4. Check Wheel Bearings and CV Joints

Sub-steps:
- Rotate the wheel by hand and listen for grinding sounds, which may indicate bad bearings.
- Inspect CV joints for any tears or leaking grease, indicating a need for replacement.

5. Address Drivetrain Issues

Sub-steps:
- Inspect the driveshaft and universal joints for signs of wear or damage.
- If CV joints are damaged, replace them with new ones, ensuring proper torque during installation.
