My tires are all balanced, and the alignment was good. The only problem with the alignment was the steering wheel wasn't straight. Over the year since I bought it, any time that I had high wind or any other reason I had to hold the steering wheel slightly left, there was a shimmy. Two weekends ago, I went on a 2000 mile road trip, and it seemed to start getting worse. On the last leg of my trip, just a few miles from home, I hit a bump and the pickup started shaking so violent I was sure I blew a tire. I checked, nothing wrong. It did it one more time on the way home and I about wrecked. When I got home everything was tight, bearings are good, etc. The next time I drove it, everything was fine until I had to make a hard left curve, it went crazy again. I got slowed down and it stopped, and I continued on. After that, I hit a bump and it did it again. Over all it is fine, but when I hit a bump just right, it goes crazy. This has me worried because I have a 300 mile trip I have to take to the airport on Monday, and then if all goes as planned, I will be moving 3000 miles away so need to get this straightened out ASAP. I have heard stabilization bars and tie rods. Any other hints? I plan on getting it to a shop ASAP, but haven't had any time, and would like to be able to do it myself. I did grab the stabilization bar and it felt a lot 'softer' than I would expect.
