1997 Chevrolet Blazer Q&A

1997 Chevrolet Blazer Question: sounds like a helicopter noise from the front end

This noise only seems to be noticiable at mainly 40+mph. I do feel a slight vibration on the driver's side floorboard while driving. In all honesty it really does sound like a helicopter, I'm not sure how else to describe it. It's not a click or a grinding. Anyone have any idea what this might be? I've previously replaced the CV Boots as well as the bearings. At that time there was more of a clicking and grinding noise though. I've never heard this noise before. -
Answer 1
I usually put the vehicle up on a rack and then have someone drive vehicle up to the 40mph speed and then listen for the noise, sometimes with a stethoscope, yes, just like a Doctor would use with a long probe. This tends to take the guess work out of the equation. here are some shops: http://repairpal.com/directory?address=55110&car_brand_names=Chevrolet -
