96 LHS Noise

I have a high mileage 96 LHS that is making a whirring noise. The
noise is independent of the engine and occurs when driving at city and
highway speeds. If I slip the transmission into neutral and coast the
whirring sound stays the same. The faster I drive the louder it
becomes but the pitch seems to stay the same. Any ideas?

 

Stick your head out the window and look up. It sounds like you're being
followed by a helicopter.

If it's not that, you may have a piece of trim or a splash guard loose.
Maybe something is scraping one of your tires.

 

I considered the idea of something rubbing on the tires and checked
it. It is very similar to that type of noise but more distinct.
Could it be CV joints? Could it be transmission related? Tranny
fluid smells ok and looks ok.

 

wheel bearing ???

 

Differential?

 

Maybe there's something hanging on one of the drive shafts. I've had
that happen before.

 

What general area does it seem to be coming from? Front or back, or one
side or the other?

 

Without more description, I concur it might be a bad hub assembly/wheel
bearing.

If the PITCH doesn't change with speed, its not anything rotational in
the driveline. I agree with a fluttering piece of trim or
weatherstripping. Check the grille area to see if everything is tight.
