I have a slight drone in the rear starting at 63 MPH. Not powertrain speed related and 6 new tires did not change it. So--- I want to inspect and repack for piece of mind. Is the jury still saying Synpower is best for rear wheel bearings? I would think a bearing would be a growl or a rump rump starting at a much lower speed but you never know.
