I notice there is a "whirring sound" that I hear when I am breaking. The Whirring sort of progressively slows down as the car slows and then stops when the car is stopped.

I thought the sound was coming from a rear axle that I knew was bad, but it has been replaced and I still hear it.

Any ideas???

That sounds unpleasant. Are you sure you aren't just braking?

I think you may have a speedometer cable making noise. It would be more noticeable during deceleration since the engine is making less noise at that time.

Sounds like a squirrel under the hood..just kiddin.Pull the speedo cable loose and lube with w-d 40. Had the same problem till i lubed it.

I am not ruling this out, but I really don't think its the speedo. Any other ideas?
