Default VIBRATION at highway speeds, need help

I'm going a dual A frame rear soon with a 5inch stretch, I'm hoping that will eliminate the severity of the driveline angles. I've put in a new driveshaft but that still doesn't seem to want to fix the problem. Possibly going to wind out my existing control arms as much as possible. I running a 4inch lift with 1/2 body lift and 2inch tummy tuck. So it's a 6.5inch lift as far as the driveshaft is concerned.

Clayton uppers and CRDSTU lowers. All running currie Johnny joints. All within a year old and not worn that I know of.

Testing new tyres later this week so that may help

All short arms?

you have probably have to have the pinion pointing 2 degrees down lower to the transfer case.

really depends on the geometry of how the axle travels under load.
ideally you would want to measure the angles with someone sitting in the drivers seat.

Going to long arms will fix lots and lots of issues...

I have long arms in the front, just waiting one cash to do the rear. I shall take some photos of my driveline angles and also get some measurements done.

I also have done a 1inch engine mount lift. Didn't change much though

If you are going custom brackets, make sure you have the sufficient separation between upper & lower arms otherwise you'll be putting WAY more load on the joints/bushes and this can lead to issues of with pinion climb.
