I recently purchased a 2000 ford expedition, knowing it needed work.
After driving it for a bit I began to notice a grinding/growling sound from the front end.
This truck is equipped with A4wd, from my research I have learned the transfer case distributes power as needed to the front, based on driving conditions and input from the abs sensors.
My truck does not have a vacuum disconnect for the front differential, so it appears to get all it's power from the transfer case.
I disconnected the 104 fuse for the transfer case motor, and now no more sounds from the front.
I'm assuming this is because all the power is now being sent to the rear, and i am confident there are bad parts in the front differential and it needs to be swapped or rebuilt.
Here is my idea/question:
Is it possible to swap in a front differential with a vacuum switch, wire it somehow into a switch into the cab for engaging the front differential, and then do the brown wire mod for the transfer case with another switch modded to put it in manual AWD or 4wd?
