2020 Rubicon JLU rear knock noise and movement at lower speed

[TJP]

Hey question for you guys. I have a 2020 rubicon JLU w 6500 miles. 2.5” RK lift and 37” tires.

Just started happening but at 10 mph when I accelerate or decelerate I feel and hear a knock underneath mid to rear.

I took a vid of it. You can see the shaft move and hear noise.

Im aware of the LSD issues going bad but this has lockers as its a rubicon. U joint, diff bearings? Let me lnow please. Stock diff.

It goes for steering TSB this week.

Video attached.

Thanks all!!

The pinion is moving up and down, likely a control arm problem. Something is loose or broken.
