Ever since I got my 2002 Acura Tl there is a noise that sounds like metal rubbing together coming from under the hood. This only happens when I am going about 70+ mph, but at the same time it is very random. When i leave for school at 7 in the morning i can hit 80 without any noise at all but on the way home from school the sound is crazy. I am embarrassed to have people in my car. I also checked under the hood and everything seemed solid. Anything i can do? I will try to get a sound recording if the problem is not solved soon.

 

high pitch low pitch thumping--potholes lane changes hard turns,,more clues please!!
and welcome to acurazine

 

well it is not a high pitch noise like nails on a chalk board, but it is not low either. the best way i can describe it as is like moving a chair with someone on it moving on wood.
The surface does not affect the noise as long as i am moving more than 70 mph
I tried to get a vid today but forgot the memory stick in the camera, so tomorrow i will have some sort of recording of the noise

 

stop by an alignment shop and ask them to inspect it for you

could be a suspension bit, sway bar end link, steering rod etc
they can tell quickly whats wrong, and can do most fixes as needed
