I just want to make it known that first, I had the problem, then I came onto the internet to look for forums. That was the only reason I even am a member of this forum, to see if others have experienced what I am. Apparently, there are a number of us.
legacysteering, I ordered the 20mm sway bar last week. It's upsetting to me to see that it did not make a difference in your situation. I don't have too much hope for mine now. I will probably install it, see if it makes a difference in my car, then if it doesn't work I will probably proceed to trade it in as I had planned to keep this car for a LONG time and I won't be able to tolerate the wandering car.
