I guess I'll retract that reply cause I didn't know that it was working. Does it move at
all in low like in your driveway - if it moves ok in high I should think that rules out a vac..
leak. Almost sounds like the control valve on the fire wall isn't completely exhausting
vac from the actuator. Maybe remove the actuator and see if the lever moves smoothly
you might have to jack it up turn drive shaft and move the lever. Has to be something
simple these axles are pretty rugged. Example of severe vac leak. Have a F6 no high
range when I pull the button to high just about stalls the engine so it has a ruptured
actuator diaphram. Meanwhile I'll keep thinking ? sam
