For full features; Go to noise when slowing down
Hello everyone, I was hoping someone might have an answer or some advice
for a problem I've been having over the past few months.
First and foremost I'm driving a 2000 Pontiac Grand AM GT, I purchased the
car used with about 12,000 miles on it and it's up to about 31,000 now with
an automatic transmission. Never had any problems with the car and have
religiously taken it in for oil changes / any scheduled maintenence. I had
the brakes changed about 6 months ago.
The problem is this: Anytime i slow down I hear a strange noise, can't
really classify it as squeaking or grinding, but somewhat like a "whirring"
sound. Its certainly not the sound my brakes made when the pads wore down.
The sound happens when i'm either slowing down or speeding up (mostly
slowing down, although i have noticed it when speeding up) once the car
gets under 20 MPH, and it happens both when i do and DO NOT brake.
I've asked my mechanic to check it out, and the first time he did change
the brake pads, that did not rectify the problem and since then he has told
me 'nothing is wrong'. It is strange that normally the noise goes away
after/during wet weather. If anyone has a clue what the problem is/might
be/ what I should ask my mechanic to check I would certainly appreciate it.
Thanks in advance for any help, please let me know if any additional
information would help.

hmmm tuff call, i would be doing a front end check, not really concerned
with the non-rotating assemblies(ball joints tie rods etc, but those parts
are still important) I would be more concerned with the rotating
assemblyies such as the wheel bearings or cv axles or even transmission
final drive unit(rare but does happen) start with wheel bearings, have them
properly inspected both front and both rear.

It might also be a problem with your tires, check them for bulges on both
sidewalls, uneven wear on the tread, have them balanced and check the rims
for trueness.

could the sound of the engine or drivetrain be softening the sound that you
should be hearing when you are speeding up?
gm transmissions can sometimes be noisy, i'm not gonna lie. i would get a
good four wheel alignment check on it, and if everything checks out okay
keep on driving it!

drive the car and put it in neutral when it is moving.does the noise
change?
then it is in the drivetrain/engine.if not,it is in something that still is
turning like a bearing.the fact that it goes away when wet is
intriguing.that leads me to think that it is something to do with ground
contact.the first gear in the transmission can make a noise like
that,especially under light load.check all the belts and pulleys under the
hood too.
