2006 Chevy Trailblazer: front end roaring sound over 30 mph, nothing shaking, just a dull roar. Stops when break is applied.

Bad front wheel bearings will make a loud roaring sound, and get louder as time goes by, check this out! God-Bless!

A roar comes from hub bearings pick up the front with a jack n shake the tire back n forth if it has play your bearing is bad

A jet engine type of noise from the engine area usually means the fan clutch is going bad. I don't think the tach is related to this, that could be the stepper motor for the tach going bad.

I have a 98 Ponitac Grand Prix GT. Soon as you start going it starts roaring. Gets loader the faster you go till 70 mph. When I am turning to the right a little while going 60 mph the sounds quiets down. Only to the right. I have replaced both wheel bearings, got brand new tires, new brakes. Didnt stop the roaring. Would it be cv axles, rack & pinion, transmission, etc?

is it a 4x4? check the front u joints.
