Solution

1. Preparation

Tools Needed: Jack, jack stands, lug wrench, tire pressure gauge, alignment tool.
Ensure the vehicle is parked on a level surface and turn off the engine.
Disconnect the battery if working on electronic steering components.

2. Tire Pressure Adjustment

Use a tire pressure gauge to check the pressure in each tire.
Inflate or deflate tires to match the recommended PSI found in the owner’s manual or on the driver's door jamb.

3. Tire Inspection and Rotation

Remove the wheels using a lug wrench.
Inspect the tires for uneven wear patterns.
Rotate the tires if uneven wear is found to promote even wear.
Reinstall the wheels and tighten the lug nuts to the manufacturer’s specifications.

4. Suspension and Steering Inspection

Raise the vehicle using a jack and secure it with jack stands.
Visually inspect shocks, struts, and bushings for signs of damage or leakage.
Check tie rods and other steering components for play by shaking them and listening for clunks.

5. Wheel Alignment

Use an alignment tool to check the alignment settings.
Adjust camber, caster, and toe angles according to the manufacturer’s specifications if they are out of range.
Perform a test drive to ensure the vehicle drives straight and does not wander.
