Hi I have a 2005 F-350 Diesel 4x4. Yesterday I put in in 4 wheel drive once I got back to hard ground I turned it back to 2 wheel. The dash light showed it to be in 4x4 still. I tried to go back and forth between the 2-4 drive. I am pretty sure that the hubs are still locked but the transfer case is not. I know the hubs work off of vaccum, but am not sure where the selinoid is nor which fuse that powers this (I do not have a owners manual). If there is someone with some knowlege of this I would be glad to listen.
Both the hubs and transfercase are locked I tried to change it from 2-4 with the engine not running to see if I could hear the transfercase change but could not. I need to know where the fuse is that controls this. I found the solinoid it was on the right hand fender.
You don't say if you're in high or low but if you're in low to shift out you have to put the tranny in N, hold down the brake, and then turn the dial to 2WD.

I have tried that several times it has not worked. I have check the plug that goes to the solonid on the transfercase and I do not get power to it when I change from 2 wheel to 4 wheel or to low. When I first put it in 4 wheel drive I went to low range but it never went past high range. once I got on hard ground it went back to 2 wheel. but the hubs were still locked I know this because the front drive shaft would spin when the truck moved fwd/rev. I could hold the brakes and only the rear wheels would spin. so now I have it back in 4wd the transfercase is locked and the front hubs are also and it will not go back to 2wd.
Yea if you put it all together I have backed up about 2 miles I have tried swerving as I am backing a little bit of everything I am going to try and tap on the soloniod and see if that might help. I just had it in 4wd when the hurricane came through here last weekend and had no problems with it? anyway if I get it out I will be worried the next time I put it back in.
Just came from the truck its out of 4wd transfer case and hubs I have done nothing since yesterday except check the plugs for power and fuses. But the problem know is it wont go back in. I guess this tells me that it is a electrical problem not just a mechanical problem like most. I have messed with so many plugs an fuses I dont even know where to start I do not have a wiring diagram on this truck. If anyone knows where I can get one please let me know.
I had this happen before & mine was the switch on the dash. Make sure the wiring connection is tight & I had a little corrosion on the terminals (gotta love the coast). Since then, I have not not had any problems.
