I have an 08 Wrangler two door, 4 by 4. This has only happened twice to me and in the same spot on the highway. There is a bit of a rough patch and my whole jeep vibrates/wobbles to the point that I have to come to a complete stop. Once I get going again it is fine. It is VERY violent when it does this. It takes all of my arm strength to get it off of the road. It only has 23,000 miles on it and is routinely taken down dirt roads without issues. I have an appointment Monday at the dealer but I like to be informed when I go in. Any ideas?? I has not been lifted or had any other modifications. It's actually Right hand drive and I use it on my mail route.
