4x4 not working?

I have an 02 f350 with the v10 and my 4x4 wont engage. I just replaced the valve that all the vacum lines go into on the inner fender next to the battery.Any other ideas? Its the electronic 4x4 and auto hubs.

Need more info- is your vac pump still working? If it isn't- your A/C will only work on the defrost setting. Also, the biggest two problems are (1) leaky vac hoses and (2) there is a big yellow o-ring inside the hubs that often leak, thus not allowing the hubs to stay locked. I personally think it's a crappy system. Convienent, but too problematic

Check all the vac lines from the canister for cracks, dislodged, etc. All the way down to the hub.
Do a search on "ESOF" for lots more info.
