With a CAD axle the front driveshaft wouldn't spin.... If it was a perfect world.... It spins.

Sorry guys, wrong thread haha.

Probably about 150 rpm while driving down the freeway.....  Sure I guess thats technically "spinning", although slow enough that you can visually count the revolutions.

 

Just because. hehe

Either way, regardless of how fast it spins, it has been known to cause vibration.

So why does it spin with a cad axle? What causes it to move?

[KATOOM]

The internal drag inside the transfer case from fluid and bearings.  I'm sure the drivers side axle is also helping it turn a small amount simply from the fluid viscosity as the spider gears move.

 

And thanks for the video Cowboy.  Thats awesome.....  Gotta love GoPro's.

No problemo.  And, umm, a... it was actually just an old camera and a bungee...

Freaking hilarious.

My front shaft when disengaged has a slight resistance to it before I can freely start spinning it, once It's spinning it is very easy to continue to do so but if I stop for few seconds then it gets sticky again. Maybe there is some sort of brake on it somewhere from factory and eventually it wears out and able to spin at will. Or maybe my seals are still that good and that's what's causing that drag, but only for a first 1/8 of revolution then it's like some one let's go the break and it's free. Not sure what it is. But maybe it does exactly what this video shows.

Any "part time" 4wd truck I've had or been around, the front driveshaft would spin somewhat like in that video.  Even an old NP205 which are completely gear driven transfer cases.

Dodge had a NP203 series of transfer case that was full time 4WD but it was a differential front to rear case so both shaft spun. Just some old history on transfer cases.
