Driver side rear... I've replaced just about every suspension part you can think of. I still have this incessant, inconsistent rattle. It doesn't always make the sound, but I guess If I had to establish a pattern, it seems to make the noise when I'm on uneven roads.
Also when you push down on the trunk, you get this squeaky rubbery sound.

Could be anything from the rubber graments on the shocks, to the exaust pipe hitting. All I can say is welcome to the sounds of an fbody.02 Z28/LS1 NBM - TIN CAN RACING

Check the spare tire hold down and the jack.

Exhaust where it crosses over top of the panhard brace is a good culprit. The rear heat shields in that area can also rattle.

Adjust your hatch bump stops

I don't know... it almost sounds like I have a loose DRIVER side tire or the brake rotor is chattering inconsistently. Bottom line the sound is coming from the Driver side and with it comes the feeling like I have an out of round tire on the driver side.
On the side note was that if the car is parked, you can push on the trunk and as the suspension compresses you can hear a squeak. I tried pushing down on it today with the hatch up and I still get the sound, so Thanks to the guy that said to adjust the bump stops... but it won't help

Did you crawl under it and check where the exhaust crosses over the upper pan hard bar like Jeff suggested? My exhaust was hitting in that area as it comes very close to coming in contact where it goes over the axle. Of course, this would be on the passenger side, not the driver side where you say the sound is coming from though.
Is the car sitting level when you look at it? Just ruling out the fact that maybe the spring is not seated properly on one side.
Another thing you could do is crawl under there and look for any fresh, shiny marks on anything metal. This would indicate where two components were rubbing against one another.

Well the only other thing that comes to mind since you have new suspension components is perhaps something needs to be torqued down again. LCA's loose, PHB loose, etc.
Does it definitely sounds like metal on metal?

Now I have also been mentioning another sound. this sound sounds like a rubbery squeak or a bad mattress/couch squeak. I can manufacture this sound every time I push down on the rear end of the car and make the suspension compress.
And I tried tightening all my suspension components down too... Worked for about a day... I'm out of ideas, that's why I got on here.

Maybe you have a bad wheel bearing

Check the king nut on the rear shocks to be sure it's tightened properly, with all the isolaters present and that the bushing is properly squashed..

Do you have spherical rod ends on your panhard bar or lcas?

Oh and sorry for the late reply... I'm in the military and put in some long hours some days.
