Personally I'd ditch that chain drive transfer case in leu of a gear driven case(rf1a) where's the rest of that trac bar? He could be your friend if he is installed.
If I have the time and money I would def plan on changing to a gear drive, maybe even move to 4.7 gears, I don't think i really need two since I am wheeling in MI, mostly sand, mud and dirt.
Traction bar is kinda on the list but at the end, I will determine after wheeling more if I need it sooner than later.
