I have a 2005 silverado 1500. This is the second time the 4wd actuator is going out on me. I replaced it about 2 years ago with another gm one and its on the downhill again. I don't want to mess around and keep spend $300 every year or two. I was wondering if anyone has found a solution to this problem or if there is a better transfer case to replace the stock one that still retains the electric 4wd?
