I have a 2007 Jeep Wrangler JK, and when I first got it a few years ago we experienced death wobble and we took it and got it aligned and put on a steering damper, and that seem to fix the death wobble...For a little while. Recently came back when I hit a pothole or a manhole in the road with one tire the death wobble starts up again. I watched a bunch of YouTube videos and tightened a bunch of bolts but the death wobble is still there.

If anybody has a solution to this problem any advice for me to check out YouTube videos etc. would be greatly appreciated.
