Mystery rear end noise

I currently have a strange popping sound coming from the rear end. Happened not to long after installing my current set up which is BC extreme lows, PBM lca’s, and Racer X rear toe links. I’ve tried just about everything I can think of including torquing all the suspension bolts messed with under load, removed rear sway bar end links, and checked for play in hubs. I’m kinda out of ideas at this point and it’s driving me crazy. If anyone’s had this issue or know of a solution let me know. (Car in video isn’t mine but is making the same noise)

When you say all suspension bolts under load, you mean the strut shaft nuts up top too, right? It sounds like that or the strut top bearing dying maybe?

I’ve done that actual strut bolts on the top. I haven’t done the one holding the top hat but I’m thinking it’s something to do drivetrain wise because when the car is cold the noise is hardly present and will rarely do it but after the car is fully warm after a drive it’s constantly doing it even when backing into a parking space pulling into a driveway etc..

Can you check your exhaust bolts. I see what looks to be condensation from your exhaust dripping between axle back and mid pipe flange. A loose connection there might explain why it changes before and after driving.

It was probably OP putting spherical bearings in critical rear suspension areas, and driving on the street.
