Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, tire pressure gauge, alignment machine.
Park the vehicle on a flat surface and set the parking brake.
Gather necessary tools and parts for inspection and repair.

2. Tire Pressure Adjustment

Sub-steps:
- Remove valve caps from each tire.
- Use the tire pressure gauge to check each tire's pressure.
- Inflate or deflate tires to reach the manufacturer's recommended pressure (found in the owner's manual or driver's side door jamb).
- Reinstall valve caps.

3. Tire Inspection and Rotation

Sub-steps:
- Use a lug wrench to loosen and remove the lug nuts from each wheel.
- Inspect each tire for proper tread depth and signs of uneven wear.
- Rotate tires if uneven wear is detected, moving front tires to the rear and vice versa.
- Reinstall and torque lug nuts to the manufacturer’s specifications (generally around 76 ft-lbs).

4. Suspension and Steering Component Inspection

Sub-steps:
- Raise the front of the vehicle using a jack and secure it with jack stands.
- Visually inspect control arms, ball joints, tie rod ends, and bushings for wear or damage.
- If any components are found to be damaged, replace them as necessary.

5. Wheel Alignment

Sub-steps:
- Take the vehicle to a professional alignment shop or use an alignment machine.
- Adjust the alignment settings (camber, caster, toe) to match factory specifications.
- Road test the vehicle post-alignment to confirm improvement.
