Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat, level surface and engage the parking brake.
Place wheel chocks behind the rear wheels for safety.

2. Tire Inspection and Replacement

Inspect Tires
- Check tire pressure with a tire pressure gauge and inflate to recommended levels.
- Visually inspect for bulges, cracks, or foreign objects.
Replace Tires (if necessary)
- Use a jack to lift the vehicle and remove the affected tire using a lug wrench.
- Install new tires (if needed), ensuring they are properly seated on the rim.
- Torque lug nuts to the manufacturer's specifications.

3. Wheel Balancing

Balance Wheels
- Remove the wheel from the hub and place it on a wheel balancer.
- Adjust weights on the rim as needed to achieve balance.
- Reinstall the wheel and torque lug nuts.

4. Suspension and Alignment Check

Inspect Suspension Components
- Visually inspect for any damage or excessive play in suspension components.
- Replace any worn or damaged parts (e.g., bushings, ball joints).
Perform Wheel Alignment
- Use a wheel alignment machine to adjust the angles of the wheels to the manufacturer's specifications.

5. Drivetrain Inspection

Inspect Driveshaft and CV Joints
- Check for any visible damage or excessive play in the driveshaft and CV joints.
- Replace any damaged components as required.
