| Re: Half shafts with U-Joints vs. CV Joints
CV is the superior piece.
As part of the design they have some telescoping travel and thus the assembly is lighter because it does not have a separate telescope function.
If properly maintained they last just as long as a U-joint.
The only problem they have on hi-perf vehicles is the centrifugal force at high speed will expand the rubber boot way out till it rubs on nearby parts. You need to put zip-ties around the smaller diameters of the boots. |
