Hey guys, I would appreciate some feedback on this... There's this weird noise that seems to be coming from the rear tires (not 100% sure though) at exactly 40mph. Not at 39 or 41mph. Only at 40mph. The same noise seems to come back at 50mph-ish but it's not as apparent. It's difficult to hear in the video but it's very noticeable in the car. I will try to take better video next time but I was wondering if anyone could identify the noise in the meantime. Thanks in advance.

Something is rattling during a resonance frequency. Could be a lot of things. Take a look at the first thread in this Forum, pinned in the blue section.

Good luck Utah
