Never considered that the front u-joint could be bad, since it has no play and looks tight. I've heard many others claiming that these cv joints are inferior to u-joints. I believe it!
Actually in the case of the WK front driveshaft CV joints > U joints.
The downside to U joints is they only have so much free turning angle, there comes a point where they begin to bind (like using a universal socket, if you have it cocked at a pretty good angle it doesnt do a good job of transfering the torque through the joint).
CV joint style eliminates the drag of a u-joint, the combine with the fact that unlike
the WJ this driveshaft doesnt move with suspension articulation it was a good choice to send power to the front differential.
BTW, for what its worth, the rear driveshaft is also non servicable, be prepaired to call around to locate another one if you attempt to repair it. The only post I have seen on here recently reguarding overhauling the rear driveshaft ended in replacing the driveshaft as the yolk was broken.
