2005 Chevy Colorado loud noise when accelerating

I have a 2005 Chevy Colorado crew cab z71. A few months ago my truck would have a loud banging noise when I would accelerate from traveling at a slow speed. It later became worse making the noise when I would be traveling at various speeds. The loud clank is heard when the truck is stopped my foot on the brake and I put it in drive or reverse. It also is heard when I accelerate and also when I take my foot off the gas. 2 days ago my 4wd is not working. Not sure if that's related
