Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery if necessary for electronic steering components.

2. Tire Inspection and Pressure Adjustment

Sub-steps:
- Use a tire pressure gauge to check the pressure of all tires.
- Inflate or deflate the tires to match the recommended PSI found in the owner’s manual.
- Inspect the tread depth and sidewalls for any signs of damage or uneven wear.

3. Wheel Alignment

Sub-steps:
- Use an alignment kit to check the camber, caster, and toe settings.
- Adjust the alignment according to manufacturer specifications using the adjustment bolts on the control arms.
- Tighten all bolts to the specified torque values.

4. Suspension Component Inspection

Sub-steps:
- Visually inspect the control arms, bushings, and struts for signs of wear.
- Replace any worn or damaged components as needed.
- Ensure all suspension bolts are properly torqued.

5. Power Steering System Check

Sub-steps:
- Open the power steering reservoir and check fluid level; top off if low.
- Inspect hoses for leaks and replace any damaged hoses.
- If fluid is dirty or burnt, perform a fluid flush as per the manufacturer’s recommendations.
