Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the battery if working on electronic components.

2. Check and Adjust Tire Pressure

Sub-steps:
- Using a tire pressure gauge, check the pressure of all tires.
- Inflate or deflate tires to match the manufacturer's recommended tire pressures found in the owner’s manual or door jamb sticker.

3. Perform Wheel Alignment

Sub-steps:
- Position the vehicle on the alignment rack.
- Attach alignment heads to each wheel and ensure they are calibrated.
- Adjust the front and rear toe, camber, and caster angles according to the manufacturer’s specifications.
- After adjustments, tighten all bolts to the specified torque values (consult service manual for exact values).

4. Inspect and Repair Suspension Components (if necessary)

Sub-steps:
- Visually inspect suspension components (control arms, bushings, struts) for wear or damage.
- Replace any worn components with OEM or high-quality aftermarket parts.
- Re-check the alignment after suspension repairs.
