do the push button 4x4 hubs suck?

I believe the vacuum source for the hubs is isolated from any sort of critical vacuum systems (for the fuel pressure regulator, brakes, etc) because in all the threads I've read about hub failures due to vacuum leaks, the only complaint/symptom is that the heat/AC will only blow through the defroster. Nobody ever complains that the truck runs badly or that their brakes are acting up.
Also, I think the little vacuum pump is only on the diesel trucks.

I'm not trying to argue with you but I am going to write out what my 2008 manual states about shifting from 2H to 4H for the Manual Shift on STOP.
Shifting from 2H (2WD) to 4h (4x4 High)
Engage the locking hubs by rotating
the hub lock control from FREE to
LOCK, then move the transfer case
lever from 2H (2WD) to 4H (4x4
High) at a stop or a vehicle speed
below 5 mph (8 km/h)
Going back to 2H is writting them same.
This is what my manual states. My 2006 manual states that the engagement for the manual shift was 3mph or less.

• For proper operation, make
sure that the arrow and the
indicator dot on the hub are
aligned, and that both hubs
are set to LOCK.
• Do not shift into 4H (4WD
High) with the rear wheels
slipping.
Shifting from 4H (4WD High) to 2H (2WD High)
Move the transfer case lever to 2H
(2WD High) at a stop or any
forward speed up to 55 mph (88
km/h).
With the vehicle at complete stop,
disengage the locking hubs
(optional) by rotating the hub lock
control from LOCK to FREE.
• For proper operation, make sure that the arrow and the
indicator dot on the hub are aligned, and that both hubs are set to FREE
No speed limit for 2WD -4WD Hi (just rear wheel slip caution). 55 MPH speed limit for 4WD Hi - 2WD. I really like the instruction about being at a complete stop before using your fingers to move the manual hubs to FREE.
Since the 2006 drive train is exactly like the 2005, I can only guess many idiots caused Ford headaches by engaging manual 4X4 with the rear wheels slipping or the front wheels turned at acute angles.
Either my 2005 is better than your 2006 or no idiots bought 2005s with manual transfer cases. (This explains a lot about my moron friend with a 2006 F250.)
Having to stop when going in and out of 4WD Hi would have been an impractical deal breaker for me.

Lock them in manually, if you use daily. My ford garage explained it like this. Auto hub is for (yes I know not Political correct) a woman stuck with her horse trailer, but if you are plowing, mudding or just know you'll need 4 wheel drive lock in the hubs, I found out the hard way, I have to lock mine in all the time, high speed spinning blew mine out and just spray some lube on the outer plastic they will turn, I found that out the hard way too and now cast aluminum is missing in the center and I have no white lettering telling which way to turn, but oh well they still work in manual. Ilearned the hard way by taking them apart in winter to get the manual to work, lots of gears/snap rings in there and I have a terrible memory, but the seal was fine no water, no water no replacement. I'm cheap by the way.

Putting aftermarket locking hubs on an "Electronic Shift on the Fly" (ESOF) truck is a popular modification, but ESOF trucks do come with locking hubs where you select between AUTOMATIC and LOCKED. This allows you to lock the front hubs even when the vacuum system fails, because you never discover the ESOF hubs do not work when you are on dry pavement, you're usually in deep mud or snow.
Are these hubs on your truck stock or an after market product such as Warn?

For now replacing auto hubs with manual means a trip to Ford for OEM hubs on 2005 -2007 trucks.

Follow these instructions:
Welcome to guzzle's 4x4 Autolock Hub Lubrication Maintenance Web Page
Also, about once a month they need to be engaged. It helps keep things moving.
Common failures are:
1) Bad Vacuum lines in the wheel wells
2) Failure due to lack of maintenance.
Other than that, not much can go wrong.
