Since switching my 17 inch winter wheels to my summer staggered 19s (with the correct size tires and OE spec Turanzas), I now notice a grinding and slight whiring on hard acceleration from a rolling start. Can't hear anything at highway speeds and shifting seems fine, no rpm surges or anything. No codes.

My indie noted that the actuator motor seal is leaking and that the symptoms are of the actuator failing. Is this plausible?
