Coming home from work the other day I crossed some train tracks and my front left wheel started doing what i can only explain as wheel hop?? It felt like I was doing about 70 and had a flat! I bought my jeep the way is sits right now, with 35x12.50's and what I belive to be a 3-4" lift. After coming to alomst a complete stop, it stopped. I pulled over and looked everything over and couldn't see anything wrong or broken. I was about 30 miles away from home and didn't have any other problems the rest of the way home. Has anyone else experienced this and if so what is the cause and what can be done to prevent it from ahppeneing again? Thanks in advance
