Damn noise passenger rear

I have a clunk or creek something in the passenger rear, has been doing it since i got the car. thought it was a spring. so i lowered the car no. figured its the shock got all new shocks NO. it sounds like its right in the trunk. where the shock bolts up i can push on that side of the car and it creeks. Push on the middle of the car nothing. any tips would be nice if you guys have had a problem like this.

Carefully inspect your control arm bushings. Its difficult to tell if they are worn until you remove them from the vehicle.
You can try spraying them with some sort of lubricant and see if the noise diminishes or completely disappears.
If it does, you've found the source of the noise.

On my car, I think that it is the worn out spring isolators that are making noise.

Yep. From your original post, the only thing thing left is the control arms.

Are the shock mounts good and tight?

installed them with an impact wrench its tight, but it did it with the stock shocks too. I'm thinking it may be the top plate where the top of the spring meets? may need a few beed welds? But I didn't notice anything wrong when I installed it.. I'd hate to take it apart again ehhh. This noise is killin me slowly... for a year and a half.

It can be frustrating tracking down these sort of noises.
It could still be a control arm bushing... That lubricant method of finding noises is not foolproof.
It seems a pretty sure thing that it is the rear suspension that is making the noise. There aren't really that many parts that move, so you will just have to focus the diagnosis on the parts that move up and down with the suspension.
Maybe put jack stands underneath the rear axle and have somebody bounce the car, while you are under it, listening for the source of the noise.

I had a weird noise like this too in my car. Sounded like it was coming from the trunk, it was actually my passenger side headrest rattling and reverberating off my back glass. Weird.

What sort of control arms are on the car? Many aftermarket ones use junk poly bushings and will always make noise. If they are stock, its probably a shot rubber one. There are the ones on each end of the LCAs, on the chassis side of the UCA and on the SRA itself there are bushings where the UCAs attach.

Could also be a broken torque box. They are notoriously weak from the factory basically just being tack welded on. Perma fix is to drop the rear, sand down the paint on the seams, weld it up solid and then weld in "battle boxes".
