I relayed it to him. He said he'll see what he can do.
I hope Dave tries it, very interesting idea.

It really isn't that type of vibration but it is. It is all due to the resonant frequencies, but a typical vibe like something being out of balance it isn't.My concern is more the vibration slowly damaging bearings, splines and seals not so much the annoying drone. Blaine, Dave or those that are mechanically knowledgibe and experiencesd with this specific issue, do you believe this harmonic issue can cause mechanical wear with known balanced driveshafts and good pinion angles? I have too many hours and thousands of dollars in my LJ that I built in the last year from stock.
It certainly can be. It isn't common for the centering ball to lose strength and let the joint flop around but it does happen. The steeper the driveshaft angle, the more likely it is to wear.I was reading an article on double cardan drivershaft design today to educate myself and I came across this tidbit.
Double Cardan joints require a centering element that will maintain equal angles between the driven and driving shafts for true constant velocity rotation. This centering device requires additional torque to accelerate the internals of the joint and does generate some additional vibration at higher speeds.
Is that bloody centering ball the cause of these vibes even if the shaft itself is straight and true?
@mrblaine any thoughts?

2006 Rubicon LJ 42RLE with balancer, 3.5 Metalcloak lift, 34's, no vibes UNTIL 488 gears, vibes start around 63mph, Now front shaft disconnected and searching for an answer

The quick answer is locking front hubs if you are vibe free without front driveshaft. . . .
I think @psrivats is onto something with his possibly, but I'm going to keep my lips sealed until Dave (the guy working on his Jeep) has some new information to report back.
