Cold Weather 4X4 Problem
Just recently bought a 2011 F350 SD Lariat.
I live in Calgary, Alberta Canada and we have had a recent "DEEP FREEZE" during this deep freeze I have tried to use my 4 wheel drive. When I use the "on the fly" wheel, I get the Wrench and the warning of "4X4 Trouble". As I drive the truck and it warms up say (about 30min) I try to use the 4x4 again and it engages but the warning is still there.
Today the temperatures were considerably warmer, and after immediately starting the truck I switched the truck into 4 Wheel drive; NO WARNING, NO WRENCH, NO NOTHING.
Does anyone have an idea as to what is going on? When is was super cold outside and I needed 4 wheel drive it wouldn't engage, traction control is useless!
Please Help!
I think I will take the advise of manually locking hubs in cold wx.

Let’s see how we can get the warning sign to disappear, aillar. I highly recommend booking an appointment with your local dealer at your earliest convenience. Also, pass on the current odometer reading; I’ll look into some available options.

The vacuum locking system doesn't seem to work all that great when it is cold.
If the hubs don't lock and the truck is in 4x4 you get the wrench / 4x4 trouble message. (something to do with the front wheels not spinning when they should be).
I have not gotten the message since I started locking the hubs in the winter.
I just went to lock mine a couple of weeks ago and they were already locked so they have been locked for at least a year......

>The hubs don’t have sensors; I believe the message comes from sensors in the transfer case. This is usually because the transfer case input and output shaft are not at or close to the same RPM to sync (Lock in) in a certain amount of time, the trucks computer produces the message. Depending on how long it tries to sync, if long enough the message won’t reset (clear) till the truck is re-started.<o

>- The hubs won’t lock because they were driven though water and in cold temperature the hubs gears are frozen and won’t move. It seems that this might be the OP’s problem because it is temperature related?<o

> - The truck is stationary and with torque on the front drive train but not moving and the back wheels are spinning. The front wheel can’t move a little bit to align the hub gears to mesh. This usually happens when you’re stuck and then you try to engage 4x4. In the winter if I get in my truck and it has snowed and I put it in 4x4 and only the rear wheels spin, I will get the message if I don’t move fast enough, but will stop flashing by the end of my driveway. <o

>I have had a Ford 4x4 for over 30 years and it is my opinion that the best thing about the locking hubs are that it saves wear on front drive train and transfer case. Every time I have to replace the $1200 front CV joints on a GM, I don’t think about manually locking my hubs in for the winter.<o
