Drive Train Repair Portland Metro area

Before taking it in for suspension work, I would look at the inflation pressures you have your tires set at. What you describe, "floating all over" is a common symptom of tires being over inflated. Check the placard on the drivers side door for correct inflation specs as per Four Winds, and then set each tire's pressures to them. The maximum pressure info embossed on each tire from the tire manufacturer is not the correct inflation spec.
