Ok, got my truck back on the road =]
My uncle machined the spindle with a lathe and smoothed it out for me, so no need for a new one =]
If you engage the front end with the hubs unlocked the axels will indeed turn in opposite directions, at least on mine cause i DO NOT have a limited slip. I dont mean both spinning backwards, i mean one going foward and one going backward, same thing as if you were to jack up the rear and spin one wheel, the other wheel will spin in the opposite direction.
In order to keep everything moving in the front end, WARN suggests to drive with the hubs locked (just locked no 4WD) for at least a half hour a month. WARN also says NEVER to engage the t-case without locking the hubs.
Aside from all the discussions here, i want to take the time to thank everyone! You have all served me some help and I have gained a good amount of knowledge from this. Its good to know that if i were to have another problem many of you would be here to help me out, and I've never seen any of you in my life. With that said, HAPPY NEW YEAR! BRING ON 2008!!! w00t <-- (Word of the year haha)

It does make sense that the axle shafts might spin in opposite directions of each other... But you also need to realize that when we're talking about using 2 Lo, it would be VERY low speed situations such as pulling a boat up a ramp, for example.
Glad you got your truck back together brother. Have a good New Years and be safe

Don't believe me? Go outside right now and turn the front driveshaft. Watch both axles spin in the same direction.
If they don't, you have something seriously wrong with your truck.

I agree, I'm not getting out either. I believe that there is a TSB reguarding this hub noise posted somewhere. I can't remember exactly what it said but your garage should check or change them under warranty, they have changed one of mine. The problem as I understand it is that the hub is disengaged but not fully, it or they are dragging on the spline of the stub shaft. Not only does the hub need attention but it needs to be taken care of pretty quickly before it damages the spline. Next time you hear this try engaging and disengaging them again. The vacuum that operates the hub only stays active for about 15 seconds and then it stops trying to disengage them, sometimes I could get mine to quiet down simply by trying a couple of times. If you install a locker or a very tight limited slip like a power-loc as I did you learn to deal with this 15 second limitation. Sometimes it takes a couple of tries. I have never had a porblem with mine engaging, they work fine in that direction.

I think you're in the wrong forum brother...
a) His truck is too old to be covered under a Ford warranty (unless he happens to have some strange warranty that he paid for when buying it used from a dealership)
b) I don't ever recall seeing said TSB for THIS era of trucks. Not to mention the fact that TSBs did not warrant free work from the dealership, that is called a 'recall'. TSBs are technical service bulletins and they are warnings to vehicle owners that there may be a mechanical, but not necessarily dire, problem with their vehicle.
c) These older auto hubs are not vacuum actuated, they're strictly mechanical; actuating through use of centrifugal force.

Yeah, he must have a 97 or newer truck. Those are vacuum operated.
nextras, you are one stubborn guy.

I have a '94 F150 XLT SWB SuperCab tricked-out by Van Works in Colorado on the way from the factory, with all the bells and whistles including auto-hubs. It's a superb ride for staying on something resembling a roadway, but be careful of the fancy ground-effects when big rocks are around. I also have an '89 F150 SWB with manual hubs. When I go out on the desert I take the '89 simply because there are a lot fewer things that may go wrong including the reliability of the hubs. Sure, it's nice to be able to push the 2wd/4wd/hi-range/lo-range automatic hubs, but it's a lot nicer out on the desert when you know for sure that you have 4wd at the turn of the manual hub. If anything ever went wrong with the '94, I'd change it to manual hubs instead of repairing the automatic hubs.
But, like the other guys here, would never presume to advise you to change to manual hubs. ;-)

The problem with the attitude of "I'll change to manual hubs when the auto hubs give me problems" is this:
When you learn that you have a problem with the auto hubs, you are STUCK
I'd rather not get into how I know that.
