Use a tire pressure gauge to check the pressure in all tires.
Inflate or deflate tires to the recommended pressure according to the vehicle’s specifications.

3. Wheel Alignment

Place the vehicle on an alignment rack.
Adjust the camber, caster, and toe angles as needed to meet manufacturer specifications.
Record the before and after alignment measurements for reference.

4. Suspension Inspection and Repair

Remove the front tires for easier access.
Inspect control arms and bushings for wear; replace any damaged components.
Check tie rods for play; replace if necessary.
Reassemble tires, ensuring they are torqued to the manufacturer's specifications.
