Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Gather tools: jack, jack stands, tire pressure gauge, alignment rack, torque wrench, and possibly a suspension tool kit.

2. Tire Pressure Adjustment

Sub-steps:
- Use a tire pressure gauge to check the pressure of each tire.
- Inflate or deflate each tire to match the manufacturer's recommended tire pressure found on the driver’s door jamb.

3. Wheel Alignment

Sub-steps:
- Lift the vehicle using the jack and secure it with jack stands.
- Remove the front and rear tires.
- Attach the vehicle to the alignment rack and follow the manufacturer's specifications for alignment angles (caster, camber, toe).
- Adjust the suspension components as necessary to achieve proper alignment settings.
- Reinstall tires and torque the lug nuts to the manufacturer’s specifications.

4. Suspension Inspection and Repair

Sub-steps:
- Visually inspect the suspension components (control arms, bushings, struts) for wear or damage.
- Replace any worn or damaged parts as necessary.
- Recheck alignment after any suspension repairs.

5. Tire Replacement

Sub-steps:
- If tires are excessively worn or damaged, replace with new tires.
- Ensure new tires are of the same type and size recommended by the manufacturer.
- After installation, perform a final torque check on the lug nuts.
