Someone had success doing that early in this thread as well. I didn't have success with it. Over about a month, I clocked my drive shaft in all 8 positions at the pinion and tailshaft and didn't notice a difference. It's easy enough to be worth a shot tho if you haven't tried it.
Do you have to take the shaft out? Not sure on how to do

So I’ve been following this conversation for months now. I’m happy to say my 2020 Rubicon no longer has any vibrations after installing a 2.5” Metalclock lift and adding 35s on Fuel wheels.

I added the wheels and tires about four days before I installed the lift. I never got it up to speed so I honestly can’t say which resolved it. But I had the off and on vibration, not terribly bad, but noticeable between 63-67 mph.

Hi Hotlanta,
I understand why this would be concerning. Have you made your dealer aware of this? If so, you may also send us a private message so we can help address and questions or concerns you have.

I have the same problem and Jeep Care said there is nothing they can do for me.

I had no change after having the tires road force balanced and the rear shaft balance checked and flipped end for end. This week I retorqued the wheel nuts to 95 ft lbs and it seemed about 50% better. Yesterday I swapped wheels and tires with a friend and it was fixed! I put mine back on and rotated them (x them) and it seems OK now. I'm convinced it is a problem with the rims!

What type of wheels/tires did you borrow from your friend? We’re they the stock rubi wheels?

there is a know problem with the front Diff on the JLs just crapping out shift into 4WD and see it is gets louder if it does have them take the front diff apart and look at the oil and gears i have seen pictures of brand new jeeps with teeth missing on the front gears and pinion.

you do know that torque spec for lug nuts on a JL is 130lbs not 95lbs

I know the torque specs of the JL but that much on the JL seems to exasperate the problem, trust me the nuts aren't going to come loose torqued at 95 lbs. The studs are larger on a JL so that's why the are torqued at 130 but the wheels may be distorting with that much torque
