try top down view. You should only need top, right/left, front/back views in order to place any object. Don't know I've never had this problem, I guees it's a matter of being able to think in 3 dimensions on a two dimensional screen. If you are still having trouble you could note the X,Y,Z coords in the attributes and manually enter the wheel to match where it goes. Other than that I can't think of any other way to place objects except to use the align icons in the edit tab.
