When you jack up car is there play in your wheels?

I would check all your control arm bushings. Also check the torque boxes where the control arms mount to.

What kind of noise are you hearing?

I was just going to say that too! If your tq box is cracked could result in exactly what you are talking about

Ah yes, almost like the hatch is rattling? Check your torque boxes. Mine were starting to tear and I had a rattle in the back like my hatch was loose or something. If that is the case you need to have a shop weld them up for you.

The torque boxes are the points where the control arms connect to the body of the car. Look for any torn welds or loose/jagged metal. They are only spot welded to the body from the factory. If you launch/hook the car hard over time they will start to rip apart. Hope that helps man.

Back in the days I use to run south side bars and this happened to me. You should be able to replace them with a reinforced one.
