Simple replacement (for me). After shutting off the water to the icemaker and removing both freezer bins (ease of access). Unplug ice maker electrical, remove bottom center screw securing icemaker and LOOSEN to two screws. Lift it out. Transfer wire harness. This was the only challenging part. The wire clip on the bottom of the unit needed some reforming to fit securely; when it came off it deformed and would not remain in place until I fixed the shape. Transfer on/off bale; Remove the bale from the BACK FIRST. The reason is the front is bent in a gentle S-shape and removing it second makes this step much easier. Reinstall. Wa La! No water drip. Prior unit had corroded through the bottom of one of the ice cube slots. Hey, it's 16 years old.
