hummm OK after doing the search thing and reading for hours, I'm thinking maybe the 4x4 module is going bad. But would like a second opinion. 2001 ST truck seems to have gone into 4x4 high on it's own, no dash lights on. I have tried cycling the switch, with no luck, still in 4x4 high. Removed shift motor, pointer say 2wd, truck still binds when driven. Lights on dash work with switch as normal. Removed front drive shaft just to get it home, that worked.

The shift motor works fine. Will move to 4h/4lo and all lights work as designed, also 4lo does engage. I have pulled the shift motor, the shift arm is set to 2h, but the truck is still in 4h. I can manually, with fore finger and thumb, move the shift arm to 4h with little to no effort, from 4h to 4lo have to use a tool. I am thinking the shift arm has broken of a shift fork has come loose. Any thoughts?
I think the pump froze up
