I am attempting to diagnose a sound that can best be described as a droning hum. It started yesterday and isn’t changed by the engine speed but does change slightly as the car accelerates. The car is a 2010 Honda Accord LX 4 cylinder with 5 speed auto trans and about 175,000 miles. The tires are Pirelli P7s with about 10,000 miles on them.
It sounds like it is coming from the driver’s side rear but when I stuck my head out the window to listen I could not hear it. Pull my head back in and there it is.
I inspected all the tires, and the suspension as best I could without removing the wheels since I didn’t have time to do that. Tomorrow I will be able to remove them and check everything more thoroughly.
Has anyone experienced anything like this?

Might be bearings. I had to replace mine at fairly low miles…
That was a great tutorial. Unfortunately I don’t have a hub tamer, nor have I ever used one. I don’t have the axle nut socket. My impact wrench died last summer. I am really handicapped on this one. What is the catastrophic failure like? How long can I put this off? And how do I know which bearing is bad?
Also the commenter who mentioned storms is dead on. I went through some high standing water during a bad storm last week.
The only wheel with play was the driver’s side rear (very little play). So I replaced it and the hum continues.
Poor diagnosis on my part. I had a friend sit in the passenger seat and he could hear it too. However, the passenger rear seemed very smooth, no noise, no play. I guess I need to look at the front bearings, and check the axles while I’m at it. On the plus side, the rear bearing/hub assembly is held on by 4 17 mm bolts and drops right off with no effort once they are removed. It only took me an hour to replace.
