Same issue a few years back. Lower the psi on the tires to like 30.

'22 Dura, '20 Gladiator Sport with only 3 options.
The tires could have brought some issues to light. I had that happen just going from 37” AT to a 37” MT. Heavier tire and it really made the shimmies come to the top. Check for worn ball joints, do the wheel bearing check.

This is all after taking it back to the tire shop and having them recheck their work. That’s where you start. You’ve already paid for it so let them earn that pay.

If that doesn’t work get it into a 4X shop. Let them look it over and have them point to exactly what they diagnose and SHOW you what is out of whack. That’s probably the most cost efficient way of doing it if it’s not something obvious.
I got mine going the other way, MT to AT. I would say it is the tires, but it isn't constant. Tires are either ballanced or not. Loose joints can be in alignment and then not. I drive 20 minutes to work. 5 of those have a shimmy and 15 don't. this can't be tires.

I have a 2020 gladiator max tow 4 inch lift rubicon pull off tires. All installed when i bought it
27000 miles and just out of the blue developed death wobble. My dealer said replace steering stabilizer with the rough county n3. I did that and it dampens the wobble to where you dont have to pull over to get it to stop. Very little off roading and everything in the font end is tight. But I do have to aluminum gear box. The gear box does have a little slack when you are sitting still and wiggle the steering wheel side to side. Has anyone had the gear box changed and cured the wobble?

Gearbox isn’t causing the wobble. Would bet it is something to do with one or more of the steering components failing. Mine was ball joints. There’s different trains of thought on whether you wanna start replacing the cheapest parts, or try to diagnose which specific part is failed. A lot of times it’s a bushing on a track bar or something like that.
