Because the CV joints
Offer a true constant velocity. This means less vibration than u joints. They are superior for a drive line that is spinning at high speed with low gearing
Does anyone else get mesmerized by the velocity changes created by an angled u-joint? Just me?

I like the standard U joint at one end. Standard U joints can be replaced as opposed to the entire drive shaft. Why not at the other end- it still must be a CV joint? Why didn't' the Bronco come with standard replaceable U joints to begin with?
To add to BigMeats’ response. They also require the angle to be near exactly the same on both ends or they vibrate. And they have to be assembled ā€œtimedā€ or they vibrate. Packaging is easier if there’s leeway with angles. I believe CV’s also can move in and out slightly where u-joints are absolutely fixed length (correct me if I’m wrong in this).

@popo_patty you still happy with your driveshaft?
Apparently I need a new one.

Edit:
Well the new driveshaft is on.
It's a good thing the old one was junk because I had to cut the damn thing off. I could not get enough clearance to get the flanges past the cups.
I was worried about getting the new one on but it slid right in no problem.
Had to cut a 6mm allen to tighten two of the axle side bolts.

Howdy how’s the spicer driver shaft doing? Worth getting over the Adams or another driveshaft for more articulation, clearance, and beef?

Ordering Adam's front and rear shafts Monday. My front shaft boot went and would rather deal with a u-joint than replacing driveshaft because of a boot that can't be replaced.

I'm going to try a universal cv boot till the Adam's shafts come in...
