Humming coming from my 01 Boxster, any suggestions on what to look for

[Jasper7821]

Found this video, kinda sounds the same. It does sound like it may be a wheel bearing. I guess if it is and turning the wheel would tell me if if it’s in the front right? No sound difference when turning the wheel would mean it’s the rear? I went through the records that are pretty complete from new and don’t see the wheel bearings ever been changed. I see axles removed and new CV boots a few years ago.

If you can find a long downhill street (w/little traffic..) turn off the engine and let it roll :-)

While going downhill turn to the Right and see if the noise increases or goes away, if increases then it will be your left side bearing, and if you turn Left and the noise increases then would be the right side bearing.

Regardless, with the mileage you should replace them at once as the other ones are right behind.. The bearings are easy to replace but it's a bear of a job to do it (physically)..
