So I was on my way to stagecoach, a big country music festival in Indo, when my truck all of a sudden took me for a ride. I was doing about 85-90 when it felt like my truck hydroplaned and my back end skipped out for under me. The freeway was completely dry, in fact it was about 90 degrees outside. The backend first when right, I straightened it out and about 100 feet later it did it again. I though I blew a tire but when I pulled over to inspect, everything was normal. The freeway was pretty choppy, but it's happened to me before just not nearly as bad. So I am on a mission to fix it. I am not sure if it has to do with the lift blocks in the rear, or my back shox, but I've had a problem with them lately feeling like they overextend. Anyone had this experience or any ideas what would cause this?
