I could use jack stands to lift both sides of the front end but I heard that this screws up the air lift system and that lifting one wheel at a time is best to avoid this. I agree this makes no sense otherwise how would technicians be able to work on the cars in a timely manner. I read it here but I can't remember which thread.One wheel at a time would be extra challenging. You will have the sway bar under high tension with the vehicle uneven.
What are you using to lift and support the vehicle? Can you not get a second set?
