Having problems with your 2003 Chevrolet TrailBlazer ?

03 Trailblazer Front End Noise/Vibration

\015 03 Traiblazer front end vibration Replaced rotors, brakes, and wheel bearings. My only other solution is the diiferential output shaft bearings are worn. If you turn vehicle to the right hard it gets worse, to the left it gets quieter. I put it on a hoist and engaged 4X4 but I could not reproduce the noise. I suppose it's from no resistance on the wheels. Any help would be nice Thanks\015 Posted / edited by AnonymousUser on : 19-03-2018

Answers :

I had similar problem with my 03 trailblazer. It had a low dull hum in the front end with a little vibration being felt in gas pedal. Noise increased over a couple weeks and was louder turning to the left and quiter turning to right. A GM mechanic friend of mine replaced the front right hub and took care of the problem. Hub was about $160 at Autozone.
When you turn left you are loading the left front wheel bearing causing the noise to increase. Turning left would switch the front load to the right side, causing the noise to decrease. Replace your left front hub/bearing.
