I've had a small clunk from the rear end and it's gradually gotten worse to it now sounding like a socket is rolling around in my trunk all the time (there isn't one). Another sound is related to the rear wheel speed when everything is cold but I think that's a diff bushing. Car sounds just fine at highway speeds with no concerning sounds above 45mpg. I ordered all the bushings to do a rear end refresh, but I'm reading a lot about the subframe mount cracks, how likely is a 2004 car to have them? Was there a model year that they started doing structural foam or is that a DIY fix I could do if it's not cracked? If it is cracked I'm planning on finding someone to weld in the Turner Motorsport kit since it seems to be the most affordable and simplest.

It's a manual 325i sedan and I'm pretty sure it wasn't beat on that hard its first 180k miles of life. The meanest I get to it is snow drifting it now and then. It still has the clutch delay value which means it hopefully has had that safety net keeping the chassis safe. Car alignment is still good and doesn't change when bumps are hit and the wheels don't seem to move when pushed but the rear right makes a springy sound when smacked.
Any help is appreciated!

I was messing around last night a bit on the way to the store and my diff bushing is also bad in addition to the other high frequency clunk noise.
When I get home I'm going to do the bushings, and if the subframe mount or anything is cracked I'll revaluate. As a control I'm going to pull the entire trunk interior out and inspect those shock mounts too!
