The most common trigger for DW is imperfectly balanced tires. Don't accept a tire shop's "good enough" tire balance, they truly must be perfectly
balanced on a vehicle with the type of front end a Wrangler has to avoid DW.
I'm not saying this is the only cause of DW but your Jeep is new enough that I wouldn't suspect anything else at this point. One more thing to check, make sure your Trackbar is TIGHT. The passenger-side mounting bolt must be tightened to 45 ft-lbs. Also, have someone steer fully back and forth (engine running) while you watch in front to look for any unusual movement that can allow DW to develop. Pay particular attention to the passenger-side of the trackbar, it should not move AT ALL, and all the ball joints as well.
There are a lot of possible causes for DW but first, I would pay a shop to take their time to get your tires PERFECTLY balanced and see if that doesn't help a lot if not cure the problem. And the bigger the tire, the more important this becomes to keeping DW at bay. Rotating the tires is not good enough in the case of DW.
