The reason most people take off the wheels is for the long screw, it is very difficult for it to bite without some sort of pressure on it. I took off the wheel, but an option though, is to just jack up the car, you don't have to remove the wheel but it gives you room to work. I put a piece of electrical tape behind the plastic that you are suppose to insert so that it would not keep rotating and let the long screw grab. Others have used some sort of glue.
