Suspension making rattling sound?

Hi guys, got another question.
For about a month now there’s been some rattling coming from the right side of my car. I can’t tell if it’s the back or the front though. At first, I thought it may be the suspension and I’d decided to just replace it. Now, two people I know have mentioned that to them it sounds like maybe there’s something loose in my rims that would be making that sound. Have any of you ever encountered this and know for sure?

Thanks.
