Solution

1. Preparation

Tools Required:
- Jack and jack stands
- Tire pressure gauge
- Wrench set
- Alignment tools (if available)
Safety Warnings:
- Ensure the vehicle is on a flat surface before lifting.
- Always use jack stands when working under the vehicle.

2. Check and Adjust Tire Pressure

Sub-steps:
1. Use a tire pressure gauge to check the pressure of each tire.
2. Inflate or deflate tires as necessary to match the manufacturer's specifications, usually found on the driver’s side door jamb.

3. Inspect and Rotate Tires

Sub-steps:
1. Remove the wheel covers or hubcaps if necessary.
2. Inspect each tire for uneven wear, damage, or foreign objects.

4. Perform Wheel Alignment

Sub-steps:
1. If equipped, set up alignment tools or take the vehicle to a professional alignment shop.
2. Adjust the camber, caster, and toe settings according to manufacturer specifications.
3. Test the alignment again post-adjustment to ensure it is within the acceptable range.

5. Inspect and Replace Suspension Components (if necessary)

Sub-steps:
1. Visually inspect control arms, ball joints, and bushings for signs of wear or damage.
2. If damaged, remove the affected components using a wrench set.
3. Replace with OEM or equivalent parts, ensuring proper torque specifications are followed during installation.
