Ok.. my 2006 Coupe makes a pop sound from the rear as the car finishes going down my slightly inclined driveway and turns onto the street. This sound also occurs when turning from the street onto a slightly inclined entrace or driveway.

It sounds like suspension ? It's sort of a popping/knock sound

What should I look at/check?

 

Look at/check your dealer! Take the mechanic with you and demonstrate the pop, and kindly request to have it fixed.

 

Yeah I was hoping someone would say "oh yeah I had that problem and it was a loose nut... tighten the nut at such and such location"

going to the dealer is no fun and a great invitation for new problems / scratches/dings.

 

I had the same thing...they did the tsb on the axle for it
