Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Safety warning: Ensure the vehicle is secure before working underneath.

2. Check and Adjust Tire Pressure

Sub-steps:
- Use a tire pressure gauge to measure the pressure of each tire.
- Inflate or deflate tires to manufacturer-recommended specifications as indicated on the driver's door jamb.

3. Inspect and Rotate Tires

Sub-steps:
- Remove all four tires using a lug wrench.
- Inspect for uneven wear, bulges, or damage.
- Rotate tires to ensure even wear (front to back or side to side, as appropriate).
- Reinstall and torque lug nuts to the manufacturer's specifications (typically 76 ft-lbs for most Toyota models).

4. Perform Wheel Alignment

Sub-steps:
- Set up the alignment machine according to the manufacturer's specifications.
- Adjust camber, caster, and toe angles as required to meet factory specifications.
- Recheck the steering wheel position and ensure it is centered.

5. Inspect Suspension and Braking System

Sub-steps:
- Visually examine suspension components (control arms, tie rods, bushings) for wear or damage.
- Check brake calipers for proper operation; ensure there are no sticking or seized components.
- Replace any worn or damaged suspension or braking components as needed.
