So, I haven't made it home from vacation to check this out, but I have a rear end clunk, like I think a lot of Aura owners have. I found this online while looking into suspension issues, shocks n strut reviews. Since our car is similar to the Malibu, I was curious if we have the same rear sway bar system. I hope not, because it looks like very poor engineering.

 

I have a clunk. But I attributed it to the fiberboard compact spare cover rattling. When I get it up on a rack, I'll have to check this out.
