Help me Toubleshoot my 4x4

[somebodyelse5]

So my 4Wheel is out again, and we just got 12" of snow last night...terrible timing.
2002 F350 7.3L with the switch on the dash

2 years ago, had a "pinhole in the vacuum line" and that kept my 4 wheel from engaging. Got it fixed, 4wheel worked all last year. Last time I used it was about 4 months ago and it worked.

Hubs are in the Auto Position

4 High does nothing, no power to the front wheels. 4 low, I can feel it "engaging" and can feel it "disengage" but again, no power to the front wheels while it is engaged.

I do not have access to a whole lot of tools, I am up at college, I have my toolset and snow covered parking lot to work in.

I'm looking for some ideas as to things to check for, if there are any, to get my 4 wheel woking.

4x4 low is engaging, I can feel and hear it....but there is still no power to the front wheels.
Fuse looks good.


Any ideas?

Have you tried manually locking your hubs?

you can try manually turning the hub to locked. then you know the hubs are in if you feel the case engaging. i have the same problem except mine is doing nothing. so i am going to put in a manual shift case.
