MY 1999 CHEVY BLAZER IS MAKING A NOISE WHEN i DRIVE

Apr 02, 2009

-   I have the same problem with some differences. When I was going to work, I had been on the interstate for about 10 miles going about 70 mph, then all of the sudden, a loud humming sound was coming from what felt like the front end. It sounded to me like I had off road tires. When I got into the city and had to brake at the first stop light, the humming sound diminished as I applied the brakes and when I turned after stopping at the light, the sound never came back....any ideas? -   mica1l
