Adjustable or non-adjustable wheel? If it's adjustable, and you have enough slack in the wiring you should be able to pull the hub out a few inches, remove the snap ring and replace the wheel (make sure the wheels are pointed straight ahead before pulling it). With a non-adjustable wheel you have to loosen the olive and pull the whole stator tube, and you'll lose most or all of your steering box fluid, so you might as well drain if first. Also, the non-adjustable wheels are secured with a large nut, and you need to be able to put a socket on it.
