Ok, so ever since I had my 8 (3 months now) I've noticed every now and then if I turn the wheel all the way to the right and backing up or moving forward, a sort of "bang" sounds inside the car (but I know it's something with the car) and I don't understand what it is. It sort of sounds as if my tire is hitting something, but I don't know. I think it does this when I turn it all the way to the left too, but I cannot completly remember. I remember my old Blazer did this and when I brought it into a shop, they said something was broken, if I bring this into Mazda will they cover it or what? What do you guys think this is?

 

If they notice the springs you may be out of luck.

 

Maybe this will help...
