I have a 2003 Ford F250. When I turn the 4x4 knob to 4x4 Low or High the light in the dash board changes accordingly but I don't feel any gear changes under like I have felt on other trucks. 2x4 & 4x4 High feels like the same type of drive but 4x4 Low you can feel it pulling harder. How can I know that my 4x4 is working properly? Any help is appreciated.
