I am trying to figure out what this noise is. I think it is the power steering going out? It only happens when I am stopped and turning the wheel or when I am making a very slow turn. Doesn't seem to be harder to turn, and it happens both directions. Also it will make a similar but high pitched sound if the steering wheel is turned either direction once it hits the max turning. I believe the latter sound may be slightly larger wheels contacting the inner well, but not 100%.
