Check tire pressures using a tire gauge.
Inflate or deflate tires to match the manufacturer’s recommended PSI.
Recheck pressures after adjustment.

3. Wheel Alignment

Tools Required: Alignment machine, torque wrench, socket set
Lift the vehicle using a hydraulic jack and secure it with jack stands.
Remove any wheel covers or hubcaps if necessary.
Attach the alignment machine sensors to the wheels.
Adjust alignment settings according to the manufacturer's specifications for camber, caster, and toe.
Tighten all suspension components to the specified torque values.
Lower the vehicle and remove the alignment machine.

4. Tire Rotation (if needed)

Inspect tire tread depth and condition.
Rotate tires if uneven wear is detected.
Reinstall wheels and tighten lug nuts to the manufacturer's specified torque.
