4x4 not working help!

I have a 2005 F250 PSD. Recently got stuck in some mud to find out the front wheels are not receiving power in high or low. The drive shaft is turning to the front axle. And both rear wheels are turning. If hubs are in auto or manual front wheel still do not have power. A/c is working fine. Any ideas?

is the vacuum pump working ?? its on the passengers side inner fender-well. you will hear it when you first tun the key on every time.
You also need to check the rubber hoses from the front knuckles for crack's
then check the plastic line to the pump for crack's.

they will not work without vacuum.

If your locking it in and it still doesn't work. you need to take the hubs off and clean them out.
My friend had the same thing happen to his truck. drive-line turned but not the front wheels.. we had to take apart the hub's and clean them out, re-grease and re-install.

here is a link.. http://www.guzzle7pt3.com/allube.php

They will and do get stuck from time to time.

Thanks sand_fiend
It sounds like the pump is working. There doesn't appear to be any cracks. I'm going to pick up a Vacuum & Pressure Tester today to test the system. I'm also going to pull the hubs and clean and inspect those in the next few days. I will let you know the result in the next few days.

Okay I have a vacuum leak, not sure where yet. Pulled the hubs and everything looks good. Gears look good, everything is spinning and working. No metal flakes and the bearings look good. If I turn the hubs to manual the front wheels still don't spin. Any ideas why with the hubs locked in that the front wheels don't spin?

Put the hubs in lock and see if the wheels turn. If so, then the hubs may be your vacuum leak, meaning they're not pulling in. If they don't lock on "lock" then there's a larger driveline issue.

Wheels don't turn when locked. Drive shaft is spinning.

jack the front of your truck up and put it on jack stands. Wheels off ground. put blocks on your rear wheels so it will not roll. put the truck in neutral "NOT RUNNING"...
crawl under and spin the driveline by hand. Look at Both the axle U joints as you turn the driveline to see if they are turning.. If So. then you have a leak at the hub.. But if you put the hubs in manual, They should lock in..
I don't know, your ring and pinion may be bad if you turn the driveline and the axles dont turn.. ?????

Replace the wheel vaccum hoses with steel wrapped, that where most problems start.

Thanks you everyone! It looks like it's just a vacuum leak. With the hubs locked in and turning the drive shaft the wheels turn. What a relief I can head up to deer camp without any worries of getting stuck. I will just have to get out and lock the hubs manually until spring and start replacing the lines. Again thank you for everyone's help what a great forum.
