CARDAN joint. A few questions

1. Do we really need on on the front of a part time transfer case?
2. Does the transfer case care if it is being attached to a cardan vs a regular u-joint?

1. Probably not. CJs don't use them, and their front driveshaft has more of an angle and is shorter. Only thing I can think of is a smoothness/noise issue?
2. No, not that I can think of.

Double cardans create less vibration, when you have a short driveshaft. If you have hubs it's not really needed since it doesn't spin all the time. But with drive slugs or a full time case, a single u joint will vibrate more at highway speeds.

the driveshaft angle is set up for a double cardan. probably not an issue at low offroad speeds.

the angles will be wrong (not equal) for a regular shaft.

Here is my thought. They came with them. So why tempt fate? Keep it lubed. It is written.

I'm kinda with Flint on this. It didn't come with that because they tried to make the car more expensive. Years ago about the late seventies. I went cheap on a front shaft on I think a 71 Chev shortbox (part-time tcase unlocking hubs etc). Yes it worked sorta but from then on I was buying u-joints by the six pack. Went through more u-joints than oil filters. Just fix the dbl cardan, keep it lubed and you're good for another 100,000 plus miles.

If your rig is stock height..ehh you can probably get away w/o it being there.
That being said, if your rig is lifted and you spend any time at all on icy roads.....keep the double cardan....period.
