2015 JKU steering wheel shakes

I am having a little steering wheel wobble at 45-50mph. The steering wheel will shake left right slightly at 45-50 and then go away at slower or faster speeds.

We checked the ball joints and its fine. Steering is all torqued up. Its not death wobble.

At 80 mph it starts again and stops at 85.

Someone suggested a better track bar? Rotated tires still an issue.

Will get them balanced next week. Been happening for the last 4K miles or so.
