My 2000 S70 has developed a thunk ( or maybe a clunk) during low speed turns ( think turning the wheel while backing out of the driveway) first on the left, now apparently on either side. Tracks straight but possibly a small amount of vibration at highway speed. Doesn't seem to act like a cv joint, no clunk on acceleration/deceleration. I will have to get under the beast for a grab-and-shake inspection, but I'm wondering if any of you folks with vastly more experience could point me at potential trouble spots before my back hits the gravel. Motor mounts? Strut issues? Any suggestions are welcome.
