noise coming from the rear of my car when I go over small bumps

Hi all,

Not had much motoring due to Covid, but I noticed around 2 months there was a noise coming from the rear of my car when I go over small bumps. The best way to describe the noise is, it sounds like when the boot is left on the latch, or the rear seats aren't quite secured, it's almost a rattle, however its neither of these!

I've taken out the boot lid plastic housing, wasnt that.

Removed the parcel shelf, not that.

Checked the spare wheel, not that either.

Any other ideas, it sounds like it's in the boot?

Edit: One Question Per Topic
Plus, this

All the best.

It might be the whole rear hatch rattling. Try removing the plastic cover on the door catch. In the two centralizers are rubber bumpers. Try rotating them 90 degrees. I have found the bumpers get compressed and no longer absorb the shock of the door moving. I dont think this a permanent fix but it might tell you if that's the problem.

Thanks, tried the above, that didn't seem to work, I seem to remember it started after I'd had the rear seats down?
But all looks good now.
Not sure if it's related, but read it could be rear shock absorbers? Is this possible?
Thanks

It's possible. But the sound tends to come from one side or the other. It's highly unlikely both have gone at the same time.
Jack the car up and remove the road wheels.
Look at the shocks, see if there is any fluid seeping around the outside of the lower shock assembly. If there is an oily film then the shock has gone.
Look at the spring and see that it's seated correctly top and bottom. Check for loose bolts/things not looking right.
