Sara, I’d call ahead and talk with the shop manager. Most good shops will always work with the customer. Explain to the manager that you need to watch the tech who’ll be doing the work, so they get the jack placed properly as has been mentioned already.
When I had mine replaced the tech couldn’t figure out where to put the jack, he almost used the axle as Bill has mentioned. I stopped him, showed him where to place it. They should be able to swap the tires out with the trailer outside the building not inside in a bay.
