Just installed on a 2004 Avalanche and now my ABS light is on. Before that, my ABS worked at low speeds but didn't light up. IDK whether it's a bad sensor or not. I will update after disassembling and checking everything again. Update. The problem was the dirt on the sensor, apparently I touched it when installing it on some kind of lube. After cleaning, the ABS light went out and stopped knocking at low speed. Upgrade to 5 stars, highly recommended.
