So my daughters boyfriends 2008 Ford Ranger truck was getting stuck in 4wd, shifting into 4wd by itself. He is borrowing my car, not a big issue, It has been 2 weeks at the shop, The say it needs a new module, and they cannot get one. Best info I have. Looking forward to your advice.

when fords loose vacuum on the 4 wheel drive it will automatically go into 4-wheel drive. a lot of times the hubs wont engage fully and you will get a grinding. the ranger should have the same or close set up as the f-150 [Ford F150 4X4 Diagnosis No Tools Required - YouTube](https://www.youtube.com/watch?v=m6b7FQOsbvI) ---

Thank you for that, what does a guy do next? Tell him to take it somewhere else? tell the mechanics what to do? Evidently the module is on backorder ---

hard to tell what’s wrong from here. it could be different things. it is there now so I would let them fix it. you said they have been there for a while, and I am sure they warranty their work. you mention that it went into 4-wheel drive by itself so I was giving you one reason why it might do it. good luck ---

Can it be driven with the hubs locked but still set to 2 wheel drive? Just disconnect the vacuum to make the hubs stay engaged until the replacement parts can be obtained. ---

> [@weekend-warrior](#): > > when fords loose vacuum on the 4 wheel drive it will automatically go into 4-wheel drive. 2008 Rangers don’t use vacuum for the 4x4. The control module is a common failure.

There’s no way to unlock the hubs on a 2008 Ranger, they’re always engaged. The problem he’s having is the control module keeps shifting the electric shift transfer case into 4x4 even while he has 2 wd selected. Pulling fuse 28 in the in cab fuse box should deactivate it. ---

@Barkydog, maybe your daughter’s friend could suggest buying the unit on line since it’s back ordered. Another possibility is to find a surplus unit. I think I’d try the on line new one myself since the price isn’t too bad. ---

I guess I will see how it plays out, we all know the won’t warranty customer supplied parts. ---

The transfer case control module comes with a 24 month/unlimited mile warranty.
