It's a tricky install. Unbolt the endlinks and the brackets (which is the easy part), then try to spin the sway bar so that the ends are on the other side of the tie rods. You'll be able to do this with someone in the car and turning the steering wheel from left to right as needed, which will allow the bar to clear the tie rods. Once that's done, you'll just need to wiggle it out from one side. Install is the reverse of the removal, although getting the new bar in can be difficult since it's thicker than the stock one. Hope this helps.
