With ball-bearing sliding axles taking the shock away when the suspension takes hits, wouldn't U-joints become a viable option as well?
Not what this is all about. A standard CV is a plunging CV, what is being discussed here is a non plunging CV. The axle is allowing lateral movement instead of the CV. A trailing arm set up like whats in a buggy requires a plunge somewhere, whether it's at the CV or in the axle.
One of the drawbacks of the U-Joint axles is they are rigid there is no torsional "give" to them. The standard axle/CV assembly acts somewhat as a torsion bar absorbing some of the shock between the wheel and the transmission.
I have a set of U-Joint axles, a damn big set, not sure if I'm going to run them or not. My car should be real light so I think it would be more favorable option than if it were a heavy car.
