Unscrew the old one, pull it out, along with a few inches of wire. Use a couple of clothes pins to keep the wire escaping back behind the oven as you unhook them from the damaged (bad) one. Then reverse the process with the new one. No big deal. Works great now and the wife is happy.
After 26 years, the element burned out. I followed the diagrams on this website. Basically, I took out the screws that hold the element in place and carefully pulled the old element forward. The wires had fittings that slipped off the old element (with a little help from the wrench.) When the wires were disconnected, I clipped the adjustable wrench on the one of them to make sure they didn't slip back through the holes in the back of the oven. The old fittings slipped right onto the new element (couple of taps with a small hammer to get them all the way on). Them I slipped the wires back through the holes and put the two small screws in the plate at the back of the element. Quite simple, even for a guy with four thumbs.
