(donation?) Hyundai Accent 2004 Timing Belt replacement

I'd like to donate but I don't see a Security Certification on your site.

My question is about my
2004 Hyundai Accent with 1.6 liter engine
It is at just over 60,000 miles

Last week, as routine maintenance suggests, I had the timing belt replaced along with the three outside belts: AC, power steering, etc

I was told there may be a screeching or squeaking noise on ignition if the belts were to stretch in the next several days and that it wasn't a problem to fix.

I am hearing a noise but it isn't what was described to me and it isn't where I expected to hear it.

What I am hearing is a creaking sound much like the creaking of walking over an old wooden floor. I hear the sound at low speeds (through parking lots etc). It seems to creak in accordance with the movement of the gas and brake pedals although it does also creak when the car bounces over a speed bump or with a sharp turn (basically any movement that is not smooth).

The sound seems to come from the front right side of the car (when facing it as if working under the hood). If I'm correct, all of the belts that were replaced were on the left side of the car.

Is there a reasonable explanation for the appearance of this seemingly unrelated noise? I will be contacting the mechanic and I would like to give him the benefit of the doubt as well as have as much info as possible. I'm worried that he may have done something to my car that shouldn't have been done.

Any info you can give me would be greatly appreciated. And once again, I would like to make a small donation, but I don't see a certification for making secure transactions and I don't have a pay pal account just yet.

Thanks a lot
Paul
