Default rattling noise at 20mph???

has anyone ever encountered a rattling noise around 20-25 mph? It sounds like something is loose inside the tranny or like someone taking a card and rubbing it up down bicycle spokes to make that click sound but with a chimey rattle. It's pretty loud and is annoying!! The sound is either coming from the engine or somehwere under the car. I've been having this problem for awhile and it is killing me. anyone ever experience this??

Put the car into Park and rev the car up and down. If you here that rattling again, it's your cat. converter. But if your going over the road mark bumps and it's making that rattling noise, it could be your springs are weak or your shock/struts or weak.

it is none of that....doesnt make noises over bumps, doesnt make noises when revved. It only makes that noise when im driving n hitting 20-25 mph. Even when I let off the gas around that time, it continues to click until the speed drops under 20mph and it stops.

Do you think it could possibly be the axles? I mean it ALWAYS makes that noise ONLY at that certain mph. My axles dont look torn nor messed up...anyone?

Does pressing on the brakes change the sound?
Lightly applying the E-brake while rolling change the sound? (Be careful or skip if it is too dangerous for you to try)
Is it a constant squeak or a on/off squeak?
Take a picture of the squeak and post it.












JK about the last one

Need more information. Too hard to tell if not heard or seen.

alright, im gonna try and record the sound and post it when I get the chance. I wouldnt say its a squeak, its more of a constant clicking sound. It is constant EVERYTIMEEE it hits 20-25mph.

gotta be a little more specific. is there a small vibration with the clicking? if so and its coming from under the hood chances are it is your harmonic balancer
