I am having the strangest issue where when I take a hard turn, I hear a horrible pop sound come from the rear suspension somewhere. It happens on both right and left turns.
I know its not the rear cause I replaced my 10 bolt already with a Moser 12 bolt. But I did hear something very similar to this right now before some older Spohn Lower Control Arms failed on me. This was over two years ago now. And I replaced them at the time with new Spohn Lower Control Arms.
I am simply at a lost about what could be making this noise. My panhard bar is a Spohn, and my rear sway bar is a BMR with Energy Endlinks. My torque arm is still stock currently.

You might want to try to torque the bolts on thr LCA and panhard rod just to make sure its not that. If the bolt is even a little under it could cause a popping sound.

I got my BMR Torque Arm to install soon, so I was planning to address the tightness of the bolts and such. Is there anything else that maybe causing the issue? And thanks for the reply.

Check the bushings in the control arms.

They are only a couple years old. What should I be looking for when checking the bushings?

Check for cracks or splits in the bushings or see if the bushings are soft. They have urethane bushings so they should be hard. Over time bushings tend to soften up.

Thanks for the replies everyone. When I got my subframe connectors and lower control arm brackets welded this past weekend, we found the lower control arm bolts at the frame were very loose, slightly better than finger tight.
Anyways, the car feels so much better out on the road, everything tight and much more strong.
