I checked the hubs to make sure they were unlocked - yes, and the noise was still there. Tested with hubs unlocked in both 4HI and 4LO and the noise was still present. I pulled the caps off the hubs and everything is in proper working order - the hubs are not accidentally engaging. Made a mark on the front driveshaft, and sure enough, when I don't hear the noise, it doesn't move. When the noise is present, the driveshaft does spin, even though the hubs are unlocked and the case is in 2HI. It feels like the front driveshaft isn't completely engaged, just partially/intermittently, if that's possible, like something isn't quite staying where it should.

So, the questions: For you NP205 experts out there, does this sound like something wrong with the case? Is it possible to adjust something externally that might help, or am I looking at something broken internally? And was this potentially caused by the occasional grinding of gears when going back to 2HI?

Any advice/knowledge would be greatly appreciated!

Check to see if the transfer case shift lever is loose. Some have a grease zerk. I you have one, grease it.

If you are from the upper mid-west, put one of your choppers* on the shift lever in the cab.


*For you non-upper-mid-westerners choppers or also known as a pair of choppers are leather mittens with wool or some other warm fabric mitten insert in the leather mitten. Choppers are effective at keeping your hands warm in the winter, serve as hockey gloves when you pass a rink with a game, and dampen transfer case shifter rattles.
