Over some bumps, I'm getting a rattly knock at the rear of the car. It's like a heavy plastic sound, or could be metal - I'm not sure. I thought it was the engine compartment not locked tight enough but that seems okay.
A garage gave it a quick check for me and said there's no play in the suspension of any sort. I've just replaced the discs and pads so it's not calipers, and it's just passed its MOT so it's nothing serious.
It's just really annoying!
It does sound like something rattling as if it's not tight enough. It's not a heat shield rattle, it's more thud-like than that. It almost sounds like a drop link starting to go, but the drop links are fine.
What could I check for, and how would I check it?
Thanks
