I'm stumped, I recently noticed a low pitch grinding/humming sound that appears to be coming from the rear passenger side. So I got a wheel bearing hub assembly and got it replaced. Noise still there. Other side was Checked and fine. But very recently I had gotten a flat tire and got it sealed up. Could it be that? Was wondering if anyone has had a similar experience or any idea.

 

Jack up the wheel and turn it by hand, should be very quiet. To rule out it being the tire, swap them front to back so the suspect one is on the front.

 

So funny I thought of switching the tire to the front just before going to bed lol
makes sense, isolate the problem
