Did you get a grinding sound, or more of an off and on humming, like something was out of balance? Mine goes in next week to check for the pinion bearings. i'm getting the humming like something is out of balance. Gets worse at higher speeds. I just had my wheel bearing & hubs done, so I know its not those. Sounds like its coming from the rear, but who knows. Mine is a 2020 with less than 60k.
