Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the 12V battery for safety while working on electrical components.

2. Tire Pressure Adjustment

Check the tire pressure using a tire pressure gauge.
Inflate or deflate tires to the manufacturer’s recommended PSI (found on the driver’s side door jamb).
Reinstall valve caps securely.

3. Wheel Alignment

Lift the front of the vehicle using a jack and secure it on jack stands.
Use a wheel alignment tool to measure the camber, caster, and toe angles.
Adjust the alignment as needed to meet manufacturer specifications (typically, toe should be set to 0° ± 1/16 inch).
Tighten all adjustment bolts to manufacturer torque specifications.

4. Steering Component Inspection

Inspect the steering rack, tie rods, and lower control arms for wear or damage.
Replace any damaged components with OEM parts.
Reconnect the 12V battery and clear any codes from the diagnostic tool.
