why wont my 4x4 work on my 1998 f150. i got 4x4 on the fly.
my 4x4 says its locked in on my 1998 f150 but the front tires dont pull. replaced front axles and actuator and still doesnt work. i feel it pulling a little bit but when i go to hit the gas a little more my back tires just spin like its not locked in. what could be the problem
