4 wheel drive not working!
I have an '01 F250 7.3L/beefed auto, Bully Dog chip, intake, and no muffler. It has an electronic t-case. My problem is I am getting vacum to my hubs but its like an open end when conected back up. I can connect a piece of hose to it and blow right through. My bearing assembly's were just replaced. Any help would be great. It's late now, have snow to wake up to. Thanks

Does the 4wd work if you manually lock the hubs?
The tubing to the hubs are made of some pretty junky rubber. Check the full length of the tubing to both sides and to and from the vacuum solenoid for tears and breaks.

Looks like the shop that installed the hub assemblies may have to re-lick their calf.
Do you know the shop very well that replaced the hub assemblies? Might have overlooked something during replacement.

The shop forgot to install the o-rings. It is a good shop they knocked an hour and the abs sensors off the original bill.(before we new of a problem) Everyone makes mistakes.
