We have been driving around during the last few days with the 4 full-time on and off in the rain / freezing rain we were getting - noticed no problems. GF picked me up yesterday, I got in and drove about 20 feet and felt a vibe/grinding/slight rattling nose. I stopped, it got quiet. I put it back in drive and the truck would not move - felt like something was binding. Reverse, same thing. I gave it a bit of gas and it started to move with a big clunk and some scraping feeling - almost like frozen brakes releasing and scraping.
I stopped, looked around underneath and saw nothing obvious, got back in, put it in 2 hi and drove back and forth slowly. It was no longer binding but there was some uneven vibration and I could feel a rumbling under my feet and hear faint rattly scrapey noises. I couldn't stay where I was so I ended up doing some driving. Noises remained.
Pulled the front DS today to try to isolate it. I found that I could turn the diff yoke back and forth about 1-2" and could see that the pass front axle U joint is pretty bad - BUT - in 2 hi I still hear some faint unpleasant rattling grinding noises even when not moving while in gear. I put it in 4 part time, truck drives. 4 full time, truck does not go (as expected)
Put my finger in the T-case fill hole and could feel the chain moving back and forth when I rotated the t-case yoke - felt normal and no play of any kind in the yoke I could detect.
Are there some things I can do to determine if it's the T-case or Tranny making these sounds? Flexplate? I did not hear (or feel) any of them before yesterday. Should I be able to turn the dif yoke back and forth like that?
