It sounds a lot harder than it is. Take off the end links and the clips around the chassis bushings and completely remove the sway bar. Cut the old bushings off with a utility knife. The new ones slide into position on the bar. The replacement bushings from Ford are pre-lubricated to make this easy. It took me about 30-40 minutes to do the whole job.
The Ford part number for the replacement bushings is F57Z-5493-BD, I don't remember what I paid but I do remember that they were not expensive. That part number will get you a bag with both bushings in it so only order one.
