- Jack up the vehicle and secure it on jack stands.
- Remove the wheels from the vehicle.
Balance Tires:
- Mount each tire on the wheel balancer.
- Follow the balancer's instructions to determine weight distribution and add weights as necessary.
Reinstall Wheels:
- Place the balanced wheels back on the vehicle.
- Hand-tighten lug nuts before lowering the vehicle.

2. Wheel Alignment

Preparation:
- Use an alignment rack and the necessary alignment tools.
- Ensure the vehicle is level and the tires are properly inflated.
Check Alignment:
- Adjust the camber, caster, and toe settings according to the manufacturer's specifications.
- Make necessary adjustments to tie rods and control arms.
Test Drive:
- Conduct a test drive to ensure the steering is stable and vibration-free.

3. Suspension Inspection and Replacement (if necessary)

Preparation:
- Gather tools: socket set, torque wrench, and replacement parts (if needed).
Inspect Components:
- Visually inspect control arms, bushings, and tie rods for wear or damage.
- Replace any worn or damaged components following manufacturer specifications.
Reassemble and Torque:
- Reassemble any removed components and torque to specified values.
Final Check:
