It seems that I always hear rattles and kwiky sounds from the rear of my FD. I removed my shitty BOSE "snake" system in the trunk and still got those sounds.

What could it be? old springs or shocks? rear window? spare tire?
Any suggestions to get rid or reduce them?

Thanks !

 

My hatch rattled a little bit. I put just a little electric tape around the metal loop portion. Just enough to go around it twice and it fixed the problem. It has fixed it for over a year and half without having to replace the tape. You can also adjust the catch back there by lowering it, but then the rear hatch may not line up properly. Besides, the tape fix has worked great and it only took a couple of seconds. This may fix your problem.

 

I just moved my latch down a little and retightened the bolts. It is harder to close now but no sound at all

 

Check your jack as well.
