please excuse my ignorance, but what exactly does a double-cardan have over a standard drive shaft? I learn best with pics.

A double cardan shaft allows you to rotate your pinion up towards the t-case output. What this in turn allows is more lift. If you don't rotate the pinion you will quickly reach the max angles of a standard driveshaft setup as you lift the truck. A standard driveshaft setup can be seen here:
Whereas with a double-cardan shaft the axle can be much lower relative to the T-case output and still not cause vibrations. The whole purpose to adding the double cardan is to alleviate binding in the u-joints and eliminate vibrations. A double cardan setup can be seen here:
Go to www.4xshaft.com then click on "tech info" at the top and then "Geometry 101" and read the article. It explains how u-joints work and everything else.

So.........to bring this thread back, are these shafts for the front or rear? It seems by looking under the truck that the rear drive shaft is at a much steeper angle than the front. Therefore, i would ASSume that the rear shaft is the vibration culprite and could be fixed by swapping it out for a double-cardan.
