toddoo,
I won't tell you anything different than what's already been stated. I've towed 7 different Jeeps, (3)CJs, (2)YJs, and (2)TJs. The last one, an '04 Rubicon with a 6" lift and a whole host of other mods for quality off roading. And, in towing all of those, all over the western U.S., I've never had any tires wear in the front, due to towing them. So, not really sure of what your problem is. If your jeep does not do bad on the road driving it, then I really can't see how this could be an alignment problem. But, I'm certainly no expert, jut have a ton of experience.
By the way, in my Jeeping days, which ended only a couple of years ago, I don't recall a Rubicon "X" model. At that time, as far as I can recall, Jeeps lowest ranking wrangler was the model "X". And, the highest ranking model was the Rubicon. Heck, I don't even remember what was in the middle with the exception of the Sahara.
So, if yours is a RUBICON X model, it's a new one on me. But, I learn things every day. That doesn't mean I'll remember any of it.
