So, you had the popping issue, replaced the RSMs and it was still there. Then you swapped the shocks from left to right and it stayed with the right side, correct?
When you swapped the RMSs out, did you carefully examine the shock tower(s) to rule out any metal fatigue or failure? Sometimes it can be hard to spot cracks. But that would be the first thing i'd double check.
This can also be a number of other things, including but not limited to:
-Swaybar tabs on the subframe are cracked. These are the mounting points for the swaybar itself and they're notorious for cracking and even snapping clean off the rest of the subframe.
-Broken rear ball joint. Inspect the ball joints (they look like bushings) on the outer connections of the upper and lower control arms. Try moving suspension parts and/or carefully prying things back and forth to see if you can spot any excessive freeplay or hear any popping like you're noticing when driving.
-Rear trailing arm front bushing pocket failure. The threaded bungs that hold the mounting bolts in can have their welds break and pull away from the chassis. Normally the force will just yank the whole bushing console out of the car, but it's possible one of them popped out and is causing the console to slap against the chassis. It's also possible you have an RTAB that's completely destroyed. Though they're pretty damn robust rubber and it would take quite a bit for it to be bad enough for you to hear it popping like that (aka the RTA slamming into the console under load).
-I'd also check the following things if the above items don't yield any positive results: Front diff bolt and diff mounts, drive axles for freeplay.
I really think this is either a bad shock tower, or an issue with one of your balljoints. Hope that helps.
