Solution

1. Preparation

Tools Required: Jack and jack stands, torque wrench, tire pressure gauge, wheel balancer, alignment machine.
Safety Warnings: Ensure the vehicle is on a flat surface and securely supported by jack stands before performing any work.

2. Tire Inspection and Replacement

Inspect the Tires:
- Remove the wheel covers or hubcaps if necessary.
- Visually check for signs of damage, uneven wear, or foreign objects.
Replace Tires (if needed):
- Use a tire iron to loosen and remove the lug nuts.
- Remove the tire from the wheel hub.
- Install new tires, ensuring the correct rotation direction (if applicable).
- Hand-tighten the lug nuts, then lower the vehicle and torque them to the manufacturer's specification (usually around 76-80 ft-lbs).

3. Wheel Balancing

Balance the Tires:
- Mount the tires on a wheel balancer.
- Follow the machine's instructions to attach weights as needed to balance each tire.
- Reinstall the balanced tires onto the vehicle.

4. Wheel Alignment

Perform Wheel Alignment:
- Use an alignment machine to check the alignment settings.
- Adjust camber, caster, and toe angles to meet the manufacturer's specifications.

5. Suspension Component Inspection

Inspect and Replace Suspension Components (if needed):
- Check for any play in control arms or bushings by lifting the vehicle and moving components by hand.
- Replace any worn or damaged parts following standard removal and installation guidelines.
