Default Hope it's not bearings

I just purchased an 03' GT Auto with 56k miles. Its very good overall shape. The question I have is, at between 30 and 40 MPH it make a whining type sound under smooth acceleration. No performance issues or shake of any kind. It does have what looks like brand new Bridgestone directional tires. They are mounted correctly.

Any ideas.

Thanks Steve

Where is the sound coming from? Under the hood? In the engine? Under the car?

It sounds like its coming from the engine compartment. Real hard to pin point from there going down the road.

Welcome to the forums.
So, when you go faster, noise goes away?
Doesn't "sound" like a bearing to me.
Belt squeal?
A/C on? (even defroster).
Try to get as many conditions as possible.

Yea quicksilverdon, its basically from around 25 to around 40-45 and than it stops. No fan on, no air on, no defroster on. It almost sounds like a gear mesh whine if you have ever heard that. It's comong from the front end somewhere. I would pin it on the tires being new, but it onlt seems to do it under acceleration. Smooth acceleration, not jumping on it. Than, all I would here is the Turbo kicking in, whick a higher pitch than this. I'm really confused and dont really want to bring it in to a dealer.

Thanks for your feedback, and thanks for the welcome. I had a 05 PT convertible when they first came out and sold it for a STS caddy. Bad move, now i'm back.

Steve

Auto or stick?
If it's stick, could be the gear you're in?

Does the noise go away when you let off on the Throttle? Our 02 is starting to make a whine about the speeds that you are talking about... Its the ring and pinon for us.

It's an auto, and yes I think it does go away when you lift off the gas. Which is weird, if it was speed related, I would think tires or transmission, or bearings. Something like that. Being throttle related gets me. I will drive it again tomorrow and try to pin it down some more.

Yep.. I would have to say its your differential section of your transmission. According to my book, I believe you can repair with the trans in the car... Maybe (I will talk to my Chrysler tech friend)

One other thing I thought of though... Our 02 whine will change if I rotate the tires. If the front tires have different tread (diameter is different because of wear) that might also cause a whine, but in our case, differential.
