- Replace any damaged tires with new ones of the same size and specifications.

2. Wheel Balancing

Sub-steps:
- Remove each wheel and tire assembly from the vehicle.
- Use a wheel balancer to check for weight imbalances.
- Add appropriate weights to balance each wheel as necessary.
- Reinstall wheels and torque lug nuts to manufacturer specifications.

3. Alignment Adjustment

Sub-steps:
- Use a wheel alignment machine to measure camber, caster, and toe angles.
- Adjust the suspension components to achieve proper alignment settings as per manufacturer specifications.
- Test drive the vehicle to confirm improved handling.

4. Suspension Component Replacement

Sub-steps:
- Inspect and replace worn or damaged suspension components (control arms, bushings, struts).
- Ensure all components are torqued to manufacturer specifications.
- Verify that no new noises or vibrations are present post-repair.
