Found the problem in 5 minutes this morning. Transfer case has gone bad. It has that extreme driving grinding in 2hi, in 4hi it grinds going into it but when I start moving it doesn’t grind anymore, and my 4lo is totally gone, it used to grind horribly going into it but now it doesn’t grind into it or do anything for that matter.
Luckily I have a spare np241 laying around the shed!
