I have a hum that sounds like it is coming from in front of me when driving. It seems to hit resonance or get a lot louder at about 50 mph and lessens at 53-55 mph. Any ideas what is causing that?
Humming at certain speeds on 1999 Toyota Camry
A bad front Hub wheel bearing could cause Humming noise you are describing. Removal of brake calipers and brake disc are required to inspect wheel bearings. You might want to have your local shop test drive vehicle for possible bad Hub wheel bearings. Hub Wheel bearings are not adjustable. Whenever bearings are removed, replace with NEW bearings and bearing oil seals.
