Solution

1. Preparation

Tools Required: Tire pressure gauge, tread depth gauge, jack and jack stands, suspension inspection tools, alignment machine.
Ensure the vehicle is parked on a level surface and the ignition is off.

2. Check and Adjust Tire Pressure

Using the tire pressure gauge, check the pressure of all four tires.
Inflate or deflate the tires according to the manufacturer’s specifications found in the owner’s manual or on the driver’s door jamb sticker.

3. Inspect and Replace Tires if Necessary

Use a tread depth gauge to measure tread depth. If the tread is too worn (below 2/32 inch), replace the tires.
Remove the tire from the wheel hub using a lug wrench.
Install new tires, ensuring they are properly mounted and balanced.

4. Wheel Alignment

Utilize an alignment machine or take the vehicle to a professional service center.
Adjust the alignment settings to manufacturer specifications (usually includes camber, caster, and toe settings).
Verify that the steering wheel is centered post-adjustment.

5. Inspect and Repair Suspension Components

Check for worn or damaged suspension parts like bushings, ball joints, and struts.
Replace any faulty components with OEM parts.
Reinstall any removed parts and ensure all bolts are torqued to manufacturer specifications.
