Sure glad you're here to do the scientific stuff. I'll be standing by.
Is this most common in TJ or TJUR or no difference?
I don't think there's enough data to say. We hear about it a lot more in TJ's, but there are a lot more of them out there.

I also have vibes with the 6-speed. I tried all this stuff, ended up rebuilding the front shaft, trying every pinion angle front and rear. It doesn’t matter what I do. It doesn’t change. With 33’s they came on at 64. With 35’s they come on at 70.I LOVE the hubs on my XJ and had pondered doing them on the LJ until I saw the price tag these days (upwards of $2k I've read here). But, if after experimentation, first up will be drop the front DS, I'll spend the coin and get it done.
Of course, I have to be part of the outlier group sporting the 6spd that 'less likely' to have this experience.
It IS good to hear that hubs might be the cure.

Where you finding them for $1400? Brand please? I'll do it if it comes to that. Haven't yet removed either DS, too buy wheelin' the XJ. I haven't even documented where they start. Do they go away at a higher speed or once they start they stay?Hub kit is the answer, but $1400!
I probably won't live long enough to wear out my brand new 35s.Or go to 37’s and they’ll move to 76!

Would a HP30 help? If so, it seems like 1400 would go a long way on a hp30 build
I don’t know. What’s the story with an HP30? How does that help vibes by raising the pinion output on the differential? So far with the LP30, no matter the pinion angle the vibes are the same.Would a HP30 help? If so, it seems like 1400 would go a long way on a hp30 build
It would lower the DS angle. I would guess @DrDmoney's hp44 would be comparable to your set up.I don’t know. What’s the story with an HP30? How does that help vibes by raising the pinion output on the differential? So far with the LP30, no matter the pinion angle the vibes are the same.
Do the big brake kits effect use of the Yukon hubs? New knuckles and all. Obviously, I'm pretty unschooled.
Do the Yukon kits maintain the same wheel width or will spacers on the rear be needed?

Dunno TJ but my XJ has Warn hubs, Dana 30, and needed 1" spacers in the rear to match the track. Works fine but don't know if I want 1" less backspacing on the TJUR. Good question, tho', probably better than mine.Do the Yukon kits maintain the same wheel width or will spacers on the rear be needed?
Sorry just saw this while heading out to the Bay Area for the week but I can get a measurement Friday when I get back.It would lower the DS angle. I would guess @DrDmoney's hp44 would be comparable to your set up.
Darren what is your DS angle?
My previous axle was a LP30 with the same (more or less) lift and I didn’t have any vibes with it and it’s been on 35’s and 4.5” of lift since it was new.The HP30 upgrade is a crap shoot. It might help with the front pinion angle, maybe. I wouldn't do it just to try and solve the vibes, unless you just want the added clearance that a HP30 gives you, plus a tiny bit more strength, going forward, that is.
I checked this today, 10.3 degrees, 5” of lift, Atlas clocked at 7 degrees, and tucked. The engine skid is lower than the DS.It would lower the DS angle. I would guess @DrDmoney's hp44 would be comparable to your set up.

Wow. Mines not clocked so its not apples to apples but I'm at 14.7.I checked this today, 10.3 degrees, 5” of lift, Atlas clocked at 7 degrees, and tucked. The engine skid is lower than the DS.View attachment 309309

Now I'm curious what the difference between the two are; like from center of front output to bottom of frame.Wow. Mines not clocked so its not apples to apples but I'm at 14.7. View attachment 309315
