My mom has a 2004 f150 fx4 and she is saying she can put in 4x4 but as soon as she moves it kicks out what could it be Sent from my iPhone using Tapatalk
I had this problem, one of the clutch plates cracked. It ended up being cheaper to swap out the entire transfer case with a used one. A more likely scenario is the shift motor is wearing out and isn't fully engaging the 4x4, I've had that happen as well. Sent from my HTC One using Tapatalk
