I've been driving my 2004 accord coupe for 2 months and while I love it its recently picked up a habit that makes me want to pull my hair out, whenever I turn I can hear what sounds like a marble rolling back and forth in the direction I turn, and when I'm cruising at over 40mph when I let off the gas I hear a small 'tick' noise, this happens whenever I turn. I checked the door panel and found nothing, i found a loose piece of metal inside the internals of the glove box which i thought was it, not so however.I noticed there are 2 little holes under the passenger seat, one of which is for the wiring harness,which may be where it is but I haven't looked in there yet,

A note is I've never heard it on the driver's side, not once. The closest I've heard it is near the passenger side center console. Someone told Me it might be control arm bushings but I just had the entire control arm replaced not even a month ago, This is driving me crazy and really damping my enjoyment of the car. If anyone has any idea what this could be, please help me

Sounds like a bad CV joint?
If you can post a video of the sound, that might help.

I'll take one tomorrow, I'm confused how it could be a problem with My axle. It's not like a consistent rolling sound, when I turn from side to side I hear it roll then stop like it hits something and stops, I'm not too well versed in cars yet can you explain why it could be that?

It's just a guess, I just reread your original post and I might have misunderstood.
But excess play in the CV joints can make sound when turning or when the rotational load changes (ie when you let off the gas).

Yeah I think I remember during my last repair my mechanic said my CV axle looked like it needed to be repaired soon but it still had some life in it, might just. Be a coincidence but the noise I hear inside the cabin sounds like a ball bearing rolling around. Thank God too because online says a cv axle repair on my car is like 3 thousand dollars

CV axle repair or replacement does not cost $3K. While I don't know how much a shop would charge for labor since I DIY everything, but I can replace a CV axle with a OEM unit for less than $300 in parts and 1.5 hours of labor. Or an aftermarket unit for less than $100 in parts and the same 1.5 hours of labor.

Okay, that makes me feel a bit better. I'll take a video tomorrow afternoon after work to get a better picture of where it could possibly be

I finally got around to taking a video, this is taken while the driver does several sharp left/right turns

Well, that does sound like something rolling around. Maybe beneath the carpet? In the footwell vent for the rear seats?

So I took it in to get looked at. They drove around with someone in the passenger seat for a while and it didn't make the noise, so they removed the seat to put their ear to the floor and dash, didn't hear anything, so then I drove with the manager in the passenger seat and didn't hear it either but as soon as he left and I drove alone I heard it. It might be an off the wall theory but it may be in the metal plate or rail underneath the passenger seat, and what's a floor well vent? Would that be under the passenger seat?

 

[DingusMcFingus]

Ok

Yes, it's under the passenger seat. Supplies HVAC air to the rear seat footwell area. I've definitely had things almost get in there.

Ay I bought a boroscope so I can look around in there, on Sunday I'll remove the seat. Look in there and if it's not in the seat I can hunt around in the vent and see what I can find. I'll report back then with either my triumphant success or crushing failure

Do you have a magnet on a stick? If you're lucky it is a bolt or nut which would stick to said magnet. Poke it under the carpeting, in the under-seat vent, etc. But it can't have a large diameter (else it won't fit in holes or under things) and you don't want a super-strong magnet.

Amazon.com : magnetic stick

Thankfully I bought a boroscope today which has a magnet attachment. So if it's under there and I see it I can gently try to remove it.
