I'm coming up to year 3 of owning my JL. I had the issue from the moment I drove it on the interstate coming home. I have changed things over the years that improved it greatly. But the steering box is the last piece of the puzzle to fix the wandering/loose steering I still have. Albeit, no where near as bad as when I first bought it. It's still a bit tiring to drive it and just doesn't feel like you can confidently put it where you want it at highway speeds.Sad.
That was what we reported day 1 with our JLU. Took 1-1/2 years to get the new black steering gear in. It's a Jeep Thing. Heard that a bunch of times.
I'm about to run out of warranty and I need to get it in to request the TSB work.
