Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Wear safety gloves and glasses for protection.

2. Tire Inspection and Replacement

Inspect Tires:
- Remove the wheel covers if applicable.
- Check each tire for visible damage, bulges, or uneven wear patterns.
Replace Tires (if necessary):
- Use a lug wrench to loosen lug nuts.
- Jack up the vehicle and remove the wheel.
- Install new tires, ensuring proper alignment of the valve stem.
- Torque lug nuts to manufacturer specifications (usually between 80-100 ft-lbs).
- Replace wheel covers and lower the vehicle.

3. Wheel Balancing

Remove Wheels:
- Loosen lug nuts and remove the wheel from the hub.
Balance Wheels:
- Mount the wheel on a wheel balancer.
- Identify heavy spots and attach weights as necessary.
- Reinstall the wheel and tighten lug nuts to specifications.

4. Wheel Alignment

Set Up Alignment Equipment:
- Use alignment tools and prepare the vehicle on an alignment rack.
Adjust Alignment:
- Check front and rear toe, camber, and caster angles.
- Make adjustments to align the wheels according to manufacturer specifications.

5. Suspension Inspection

Inspect Suspension:
- Visually check control arms, bushings, and struts for wear or damage.
- Replace any worn components.
Tighten Loose Components:
- Use a torque wrench to ensure all bolts are tightened to specified torque values.
