Ever since I got this truck it has made a noise in 4wd. We eliminated the driveshaft, not that. Not the hubs, brand new. Pretty sure its not the transfer, sounds too far forward, but is on the right side for sure. Has anyone ever seen worn inner shafts on the passenger side on a dana 44? That is my thinking. I am working up to pulling to axle. Since it's all snowy 4wd is needed more now, its on a DD so it doesn't see 4wd much.
