Question What's wrong with this drive shaft?
Theksmith gave me this front drive shaft a long time ago. It came off of his WJ when he upgraded to JK axles. I installed it on Clifford recently, and found out that, when in 4 wheel drive and the Jeep is under load (i.e.: going uphill or making a hard turn) there is a clunk sound for every revolution of the drive shaft from the CV joint.

I took it out and looked it over, and I think I know what the problem is. Besides the caps are missing, what do you think is the problem?

If the ujoints are tight, the centering ball in the CV is most likely worn. Replaceable. Be sure to get one that can be greased.

Ditto what Tim said. Also, be sure to look closely at both the driveshaft yokes, and the mating yokes at both the t-case & the axle, to make sure there are NO witness marks where the yokes may be interfering.

Looking again, the ends look out of phase.

Good catch Tim ! ! ! It does indeed appear as if the slip yoke is mis-positioned by approx one spline.

Yes the u-joints are misaligned. The cv joint is tight and nothing hits or rubs. I pulled the yoke off and rotated it one spline and it misaligned the other direction. That slight misalignment must be causing my clunking.
