Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and the parking brake is engaged.
Wear safety glasses and gloves for protection.

2. Tire Pressure Adjustment

Use a tire pressure gauge to check each tire's pressure.
Inflate or deflate tires to the recommended pressure as stated in the owner's manual.
Recheck pressures after adjustments.

3. Tire Inspection and Replacement

Remove any wheel covers or hubcaps if necessary.
Inspect each tire for uneven wear patterns or visible damage (cuts, bulges).
If tires are worn unevenly, rotate them or replace them as needed.

4. Wheel Alignment

Use an alignment machine to check the vehicle's alignment.
Adjust the camber, caster, and toe settings according to manufacturer specifications.
Tighten all adjustment bolts to the specified torque values (refer to the service manual).

5. Suspension and Steering Inspection

Check for play in the steering wheel by moving it left and right with the vehicle stationary.
Inspect the tie rods and control arms for any signs of wear or damage.
Replace any worn or damaged components, ensuring proper torque on all bolts during reassembly.
