There's no general photos on that inspection link, just corresponding inspection photos. That being said, generally looks and sounds like a SMB 4X4 build, Atlas, leaf sprung. Clearly someone who had no idea how to properly engage the transfer case fudged that thing up, hope it wasn't you testing out the 4X4 system!
BTW-your sway bar is not broken, just the mount.
There's a few things you can do to improve the ride, those SMB conversions can be harsh with that leaf sprung front end, for starters I'd ditch those Rancho shocks and put in the re-valved Fox shocks from SMB, big improvement, or for a bit less, some Bilsteins.
