I’ve been trying to troubleshoot why my 4wd isn’t working and this is what I’ve found but cant seem to figure out the exact problem.

-when i turn the **** from 2wd to 4hi or 4lo, I hear the clicking from the module

-when I turn the ****, the 4hi and 4lo light comes on the dash

With those two things working, I know it’s not a relay or the module

Next,

- I can spin the front driveshaft by hand when it’s NOT in 4hi or 4lo. But I CANT spin it myself, when I turn the **** to 4hi or 4lo.

- Does this mean it’s NOT the transfer case motor? If the front driveshaft is activated when I activate the 4wd? Could it possibly be something wrong with my hubs? They are automatic hubs, not manual.


Does my ford have pulse vacuum hubs?
