What did you do to your NBS GMT800 Tahoe/Yukon Today?

Well, damn. Maybe someone is pranking you with the ol' zip-tied driveshaft trick.

No zipties, but I did find some of these duct-taped to the driveshaft :

While I was troubleshooting this, I removed the driveaxle on that side and went for a testdrive - the noise was still there.
I did notice a rip in the upper balljoint boot and a lack of grease inside.
I began removing the upper control arm but, of course, the balljoint stud decided it wanted to spin. Now I have to sawzall it off. I couldn't even get a visegrip to stop the spinning.

Drove it without a CV shaft? Did you have a spare splined hub to hold the wheel bearing together?

Nothing's gonna happen.

Man are those control arm bolts a ***** to remove !
I've been taking out my frustration on those mo-fos all damned day and still they remain, laughing at me.

Oooooo, that's a good one! Never knew about that one lol.

Back when I was a grease monkey, I did this to the lead mechanic's truck. Driveshaft looked like a bottle brush when I finished.

I think the O.E. ones are fine, but a few of the aftermarket that are 4wd specific will come apart without the axle nut on to hold it together. If it was going to fail, I think it would of happened by the time you made it around the block.

if you think the wheel coming off is nothing...well then nothing will happen. the fender damage is pretty cool too.

I've seen a 4x4 hub FAIL right in front of my eyes one time. The axle was removed from the LF hub and driven, it came apart pulling into the shop. Wheel fell off, fender damage happened, and messed up the tie rod from the landing.
