On the truck, typical Ford problems, had both ball joints replaced and control arms on the front replaced. Also had a problem with the 4x4 disengaging....it's the shift on the fly type. No vacuum leaks, but they took the actuator off and cleaned and relubed it. Shift fork was not bent. Now it all works as it should. Checked the front pumpkin, fluids were fine. All told.....840 dollars.
