I don't want to trust trouble shooting to the caliber of people in some of the local reapir shops but with suspensions - I need help. I would like to have a little knowledge to tell them what to look at so......I have a vibration and at very low speeds, like crawling along in traffic, the steering wheel oscillates (rotates back and forth) slightly when the car is rolling forward. You guys with suspension know-how - Is this a wheel out of balance? Is it something else? It smooths out at high speeds but there is a subtle vibration at all times. Appreciate any ideas.
