Less power loss in the drivetrain?
Weight?
U-Joints has the characteristic of causing the drive shaft to actually speed up and slow down with every revolution of the shaft. This behavior is counteracted upon by the U-Joint at the opposite end of the shaft, so the user never feels this affect. This is really only an issue if the drive is running at an angle and the more angle, the worse the affect. So in the Pantera, this issue is minimal. The CV Joint doesn't suffer from this affect. As the abbreviation suggests, it is a Constant Velocity joint. So in theory, it does run smoother, especially in higher angle situations.
One could argue that they look way better and modern and don't have the tendency to throw off grease like the U-Joint do...
If also provides more clearance for the exhaust and sway bar.
I would argue that it is stronger, especially if you upgrade to M300 axles.
The axles are also torsional in design, so they are MUCH easier on the ZF. The driveshaft’s will transfer all the shock loads they experience straight to the ZF, but the torsional axles will buffer these shock waves and potentially save you thousands of dollars in repairs for that one burn-out that experienced wheel hop, that you shouldn’t have done!
And finally, and this is a biggie, if the CV joint breaks, the axle should stay retained in the joint, and not pound the hell out of the car.
Not sure about less power loss, but I wouldn’t bet against it…
I do not believe that the assembly is going to save much weight at all. In fact, the CV joint setup may be a pound or two heavier.
