03 Hemi Ram 4x4 clicking/grinding noise

I recently bought an 03 Hemi Ram 4x4 and it has a nasty clicking/grinding type noise in 4wd when turning the steering wheel. If going straight it's fine. The driver side cv joint was bad, so I replaced both sides thinking this would stop the noise, but it didn't. Not sure if this is related, but when driving down the road in 2wd, it sounds like I'm dragging a chain underneath the truck. It's not real loud, but I can here it. Anyone have any ideas?

Dood, it sounds like your truck nuts are draggin'. You gotta pick em up dawg. Can't treat yo nuts like that.
