That rules out a failing CV. Sounds like a failing wheel bearing to me. It is possible that a sticking caliper can cause an intermitted drag feeling after you apply the brakes, but it won't just start when you are driving and then stop.
One other possible source of that kind of behavior is some wire or other junk that got jammed into the caliper housing and is interacting with the brake disk. Uncommon, but it happens sometimes.
Get you car checked out by someone familiar with bearings, disc brakes, etc.
“... a sticking caliper can cause an intermitted drag feeling after you apply the brakes, but it won’t just start when you are driving and then stop.”
And that’s exactly what happened today, unfortunately. Driving on a country road back home at 45 mph and the drag/rub lasted about 2 to 3 seconds.
Thank you so much for your advice.
