Default WRX Rear Suspension Pop

Hey guys, looking for input. 2018 WRX Premium.

A month or so ago I started to develop very distinct popping noise coming from the rear of the car. The noise only happens when turning left sharply with a bit of speed or when the car is twisted such as over and angled speed bump. Itís generally a single louder pop and then when the car straightens out, a second quieter pop. As if something is shifting in and out of place.

Initially I thought sway bar/end links but I torqued everything and eventually just replaced the end links and bushings to no avail. The car is stock except for RCE black springs (~8-10mm drop)

Thoughts?

Could be your axle CV joints.. I did an sti swap with new axles.. they've lasted only 11k miles! Poping and jerking mainly on cornering. Gonna drop some DSS 800hp axles for replacement!

I initially thought that since I had an axle prematurely go on my Fozz. But as much as I try, I canít get the pop to happen more than once while turning. Did yours exhibit multiple pops through a corner or just a single?
