Front Drive Shaft Question on a 4X4

I just found out yesterday that the squealing sound I have been hearing is a bad U-Joint on the front driveshaft. I have two questions....One - Does the front driveshaft spin even though 4-wheel drive is not engauged? If it dosent, I cant see how I can hear if the u-joint is bad unless 4-wheel drive is engauged. And Two - I am going to attempt to remove the front drive shaft to see if the noise stops, is this hard to do? A basic how-to would be appreciated. Thanks!

Seems to me that you would hear a big difference in a bad U-joint there depending on whether 4WD is engaged or not. Can you could go under the truck and twist the shaft to see if there is play in the U-joint?

There is a little bit of a click when I push up and down on the drive shaft but no major play.

Sounds like you need that entire double cardan joint replaced on your front propeller shaft. That center, double yoke assembly is what goes bad. It has some type ball bearing setup or something in the center. A lot of guys don't know it's there, actually. It's that center setup that's bad. Probably.....lol, don't quote me. They make a horrendous squeal that keeps perfect time if you hold the pedal in one place. Sounds like dull rubbing metal.
Good luck to ya.
AND PS...replace the front cardan joint at the same time, if you haven't already.
Adios!

That sounds like what I have to do. You described the sound its making perfect, I hear it at all speeds over 10mph. I am still not clear on weather I should hear this sound when in 2WD since this u-joint in question is on the front drive shaft. What i am really asking is does the front driveshaft spin at all with the front wheels when 4WD is disengauged or does it only turn when 4WD is engauged. If it does not turn in 2WD, the sound is coming from somewhere else. I am having another shop take a look at it for a second opinion before I do anything.
