The connector is fine. It shifts into and out of high/low fine. The dash indicates when it's in neutral as well so I'm stumped. I just powerwashed the underside and beat on it some more with the motor running. Still no go. I guess I'll be pulling the front drive shaft later today.
The only thing I did after getting out of where I high centered is I went back and went over the same spot with more speed. I got through fine and didn't think I abused the truck. It's just weird. If I can't figure it out I'll take it down and have Oleg work his magic.
