4x4 confusion

Ok so my buddy noticed today that as i was backing out of his garage that my front drive shaft was turning. It wasnt in 4 wheel and the front drive shaft is turning when ever i move anywhere. Why is this, does it have something to do with the command trac that my jeep has on it. I am kinda confused. Please help.:conf used:

The front shaft is always turning. It is connected to the differential. It is engaged/disengaged at the transfer case.

If your front driveshaft is turning while not in 4x4 it means the yoke isn't tight probably from driving on speed bumps too fast and/or the lead in the shaft was exposed to too much radiation and it's warping. This will lead to a terrible vibration and eventually the driveshaft will bomb probably while going 70mph down the highway, throwing shrapnel into every vehicle within 100 yards of your Jeep. In addition to that, you'll probably lose control, veer off the highway, and run over a basket of baby kittens

you need to romove it ASAP and take it to a shop. Tell the guy there you need "one of those bomb-proof shafts you read about on zee internetz that don't spin."

While having the bomb proof shaft installed tell them to check the blinker fluid. Low blinker fluid will cause the drive shaft to spin uncontrolably.

Be careful as there was a car made that did have muffler bearings so you really can't use that one anymore.

Make sure after the install the shop applies plenty of RTV to the transfer case. My buddy got a new shaft installed and after 100 miles or so it started making noise. They drained out the TC oil and shipped it to a lab in Tijuana to get tested and it was discovered he got Sea Monkeys in the transfer case from driving in mud with a improperly sealed driveshaft. It cost like $2000 dollars to fix and a few "adult favors" to the Jeep dealership.

My friend and Chrysler are still duking it out in court too.

I always have them rotate my battery after adjusting the muffler bearing.. should be included in the cost.

There are now muffler bearings in the new diesel exhaust systems. They have an atomizer of some sort that spins to disperse the urea that is being used on the new systems. Who'd a thunk it?

The car that actually did have muffler bearings was the Dodge Stealth RT twin turbo. If you purchased one with all the options there was a switch on the dash that directed the exhaust differently through the muffler. I can not remember if it was a sound or performance thing or both, but to make that change happen the rotating shaft inside the muffler had bearings.

This entire statement make me but the bold area in particular cracks me up. Not because I think it's funny to run over baby kittens, quite the opposite, but because who would think to put that in there?
