if you need a third hand, get you some safety wire or a zip tie, you can use it to hold "things" were you want them and then simply clip them with a wire cutter when you are done.
Another little tip, have a bladed thin somewhat long screwdriver handy when you lift the wheel, you can use it to pry the swing arm enough to get the wheel in, works for me..
and if all else fails.........get a bigger hammer!!
