2005 Silverado 1500 disengages out of 4hi. I’ve searched forums and only find were people have issue with trucks engaging into 4wd while in 2wd. Mine is the opposite. I live in Alaska so during winter time 4wd is used very often. Last year I changed front axle actuator and that obviously didn’t fix it. It will make a couple popping noises then goes into 2wd. Any ideas?
