Solution

1. Preparation

Gather required tools: socket set, jack stands, torque wrench, alignment tools, and tread depth gauge.
Ensure the vehicle is parked on a flat surface and secure the vehicle with wheel chocks.

2. Check and Adjust Tire Pressure

Use a tire pressure gauge to check the pressure of each tire.
Inflate or deflate the tires to the recommended pressure as specified in the owner’s manual.

3. Inspect Suspension Components

Safely lift the vehicle using a jack and secure it with jack stands.
Visually inspect suspension components (struts, shocks, and control arms) for wear or damage.
Replace any damaged or worn components with OEM parts.

4. Perform Wheel Alignment

Use an alignment machine to check the alignment settings.
Adjust the camber, caster, and toe angles to meet the manufacturer's specifications.
Tighten all components to the manufacturer-recommended torque settings.

5. Rotate and Replace Tires if Necessary

Rotate the tires to promote even wear, switching front to back and side to side.
If tires are excessively worn, replace them with new tires that meet OEM specifications.
