I just purchased a Smittybuilt Hitch for my 2012 JKU Sahara. I needed something just for hauling my bike rack around. Got a great price at my local 4 Wheel Parts.
I had to remove bolts from the rear bumper to install the hitch. It took some time, but it installed perfectly and looks great. Make sure that the Jeep is cool, as your hands are right next to the muffler. Here are some pics. First one is the hitch. Next two are the bolts I had to remove from the bumper. Last one is the finished product.
