Solution

1. Preparation

Gather tools including a jack, jack stands, tire pressure gauge, and a wheel alignment tool.
Ensure the vehicle is parked on a level surface and set the parking brake.

2. Tire Pressure Adjustment

Use a tire pressure gauge to check the air pressure in all tires.
Inflate tires to the recommended PSI as per the owner's manual.
Recheck pressure after adjustments.

3. Tire Inspection and Replacement

Remove the front tires using a socket set.
Inspect tread depth and look for any unusual wear patterns; measure using a tread depth gauge.
If tires are worn unevenly or below safe tread depth, replace with new tires.
Ensure new tires are properly balanced if replaced.

4. Wheel Alignment

Set the vehicle on an alignment rack, ensuring it's level and secure.
Adjust the camber, caster, and toe settings according to manufacturer specifications.
Tighten all adjustment bolts to the specified torque values (refer to the vehicle’s service manual for specific torque settings).

5. Suspension Component Inspection

Inspect all suspension components for signs of wear, including bushings, tie rods, and control arms.
Replace any damaged or worn components using appropriate tools.
Reassemble and torque all fasteners to specification.
