what could cause a loud hum from the front passenger wheel as i reach 20 mph on a 1989 cadillac seville sts
as i reach 20 mph i hear a humming noice from the front passenger front wheel what could cause this i pulled the wheel off and cleaned the abs sensor that was covered was covered with grim took a look at the brakes and checked the tire for abnormal wear and everything looked fine
Hub bearing...put the car on jack stand and look for play when u hold the tire side my side and kind of give it a heavy shake left to right
Two other ways to check for a bad hub - when driving turn the wheel slightly to the left - if you have a bad hub, it usually gets louder. Second way is to raise the wheel, put the car in neutral and spin the wheel while holding onto the spring. If you can feel the balls grinding in the hub, it's bad.
I AGREE EDSCALADE WITH BOTH ZBOY AND TENSPEED.LOOK ON EBAY UNDER PARTS AND ACCESSORIES, COMPARE WITH PARTS STORE PRICE. GOOD LUCK AAACAR
