Thanks for the responses, guys. I had new brakes put on and the front wheel bearings repacked, it seems to be happening much less often, and with much less force when it does, and it doesn't last as long. It started doing it early yesterday, and it stopped immediately when I took my foot off the gas. Did this twice to confirm. It's more likely to do it after a left turn or going around a curve to the left. But later, it just did it out of the blue, even with my foot off the gas. Weird. Sounds like it's time to get in and start checking the other front end components.

I have a '97 Legacy Outback wagon that has intermittent steering shimmy. When the shimmy occurs, it's like somebody is grabbing the wheel and moving it up and down. It can go from very gentle to pretty strong at times. I noticed that if I take my foot off the gas when it happens, the shimmy immediately stops, and if I hit the gas again, it starts. I've taken it to my mechanic 3 times, but it won't seem to do it for him, and he says he needs to feel it to fix it. It's driving me nuts. Anyone have an idea what could be causing this?
