vibration and drone noise?

mossie · 10-05-2007, 08:18 PM

My 2001 s-10/trailblazer trim 4x4, 4 door has just started making a noise that is best described as a drone. It doesn't do it until I get up to about 40 mpr. but it gets the loudest around 55; this is in 2wd. So far front and rear differential levels topped off, tires rotated, grease and front end components checked including wheel bearings and cv joints and it's still doing it. It's loud enough to really be annoying. There is no grinding sound but I can feel a slight vibration in the pedal and riders also say they can feel the vibration in the floor boards; it still does it on wet pavement or gravel roads so I am sure it's not the tires. I am concerned that it may be something inside the front axle. The truck has 56,000 on it. Anyone have any ideas or similar problems?

My 2wd did that and it was the front wheel bearings.
