"CV Axles"

http://www.quadratec.com/products/52400_1904.htm

I have a question about those things: why would they be any stronger than a U-joint axle? It is my understanding that a CV joint still uses U-joints. So wouldn't that just be a regular U-joint axle with a cover around the U-joint?

Right from the page you linked:
No U joints... They basically spread out the load over a greater area, making them much stronger and reliable. You can read the little captions on the photo that explain why RCV are better than standard U joints. I run RCV shafts and love them. They work expecially well with lockers when the wheels are at full turn. Oh and this too: "backed with a "No Questions Asked" limited lifetime warranty."

CV is used to mean constant velocity joint, which all joints are so cv is used as another meaning for u-joints.

But we use cv to describe joints that run larger angles such as dual cv's or joints used in a h-yoke, the above picture we call rzeppa's since it is a rzeappa joint, however it is another form of a constant velocity joint.

The rzeppa design is better

Okay, I get it now. I didn't see that image on the Quadratec page. Ball bearing design is superior....... but it makes me wonder how well it handles dust, dirt and mud. I can't imagine the polyurethane cover keeps it 100% sealed.

Does their "limited" lifetime warranty allow you to send broken shafts in for free replacements?

The boots are the hardest part to install. It takes a lot of strenght to put them on - if I remember right, the instructions mention having someone help you burp air out of the boot cover with a flat head screw driver while you push it down over the rcv end - that should give you an idea of how good the seal is. Plus they're packed with grease. Probably sealed better than any rubber CV joint boot on the market. Ive personally gone through sand/mud/deep water with zero issues.

Unless its changed since I purchased them, the warranty is: “You break it and we’ll replace it”.

Their web site covers just about any question you may have.
