[Oh Haha]

I have been trying to solve a vibration issue the past few months. I replaced the front suspension bushings, tie rods, and ball joints. Still there but better. I had the tires balanced a couple of times by different shops. I finally figured out that I had flat spotted a tire last year in a panic stop. Never even gave it a second thought before now. My tires were getting old anyway so I replaced them yesterday with new. Rock solid now!!
As with most problems, check the simple things first. When were your tires balanced last? How old are they? Over 5 years and they tend to do weird things. Good luck and post what you find.
