Driveshaft clocking / oscillation

[commbubba19]

My 392 has been having an oscillating vibration around 55-65 mph. It starts and I feel it in the body and seat for a few seconds. Goes away for a few seconds and then comes back. The pattern repeats.

I’ve rotated tires front to rear and right to left. I never get the usual steering wheel shimmy from an mis balanced tire.

i read one owner found their driveshaft was not clicked correctly based on the paint markings and taking a look mine are off too. Atleast based on what I can see. Would like another opinion.

the front of the driveshafts yellow marking is 180 from the flange.

I ordered a second OEM driveshaft and sent it out to get balanced.
for my 2022Jeep. That Jeep is being (defect can not be fixed) exchanged for a 2024 Sahara. I plan to sell it if interested. Repair was not made by the dealership as none of them have the equipment.
