Haha no...not yet. Getting ready to burn sliders on in the next couple weeks. Hopefully have bumper with tire carrier on to also haul hi lift, 10 gal fuel, etc by end of next month to have that weight there. Also I believe the spring say 300 to 400 pounds. However I will say I've been taking a few hour drive each way the pastcouple weeks moving. When loaded the vibes are worse than when unloaded. This has me worried for all the weight I'm about to add.

, and the others above. I agree it u joints. Although to be clear when I say rpm specific I'm meaning rpm not speed. This isn't I notice between 60 and 70 mph ( 1800 to 2500 rpm). This is 1800 rpm to 2500 rpm. Speed not a factor. So first gear in that rpm range vibes hit, second gear in that rpm range vibes hit, third gear...you get the idea. I say this cause im used to u joints being speed dependant.
However it does feel driveline and it does feel like u joints. This is what brought me back to my pan hard setting...but no one has commented that it looks off to them.

I agree that the side to side fight with regular up and down fight might be a thing. Again this is why I'm asking about the panhard.
My u joints feel fine when driveline attached. But I know they may not be after enduring this abuse. I will swap them/or driveline once issue is resolved. Or at least lessened as the abuse may have the u joints wrecked enough to be an attributing factor. But like I said same vibration after 3 drive lines so there's something else going on.
