Should I Use a Splined or DD Shaft?

Yes, these are the joints I used also.....As mentioned you have to file/grind a recess half moon in your shaft to get the bolt from the joint through but this prevents the shaft from falling out should the bolt ever loosen up......Kind of a safeguard....Also, I want to mention that you have to really really tighten the allen bolts on the unisteer u-joints to get them to cinch....I believe they say 75 foot lbs. on their instructions....

Yes, everyone has to realize that the bolt doesn't just tighten into the threads like a normal bolt installation...it has to squeeze the split joint to make solid contact with the shaft splines/DD. So in essence your tightening the bolt and compressing the split joint. I try and get some vice grips or a small clamp to squeeze the split joint tight so the bolt gets to torque properly in the threads without having to also squeeze the joint together. It's not a deal breaker, just something I do to ensure that the split joint is "clamping" good up against the splines/DD shaft so that the torque is not fighting the split joint as you torque the bolt.
