Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure safety.

2. Inspect and Replace Tires (if necessary)

Sub-steps:
1. Remove the wheel covers or hubcaps (if applicable).
2. Use a jack to lift the vehicle and secure it with jack stands.
3. Inspect each tire for signs of wear, bulges, or punctures.
4. Replace any damaged tires with new ones of the same size and type.
5. Reinstall the wheels, torque them to the manufacturer’s specifications (usually around 80-100 ft-lbs).

3. Inspect and Replace Suspension Components (if necessary)

Sub-steps:
1. Remove the wheel to access the suspension components.
2. Check the condition of control arms, bushings, and strut assemblies.
3. Replace any worn or damaged suspension parts.
4. Reassemble and torque to specifications.

4. Address Drivetrain Issues

Sub-steps:
1. Inspect the driveshaft for any visible damage or excessive play.
2. Check the CV joints for cracking or leakage.
3. If damaged, replace the driveshaft or CV joints as needed.
4. Ensure all connections are tight and secure.
