My 06 supercab that is still under warranty has been and is at the dealership for this rattle/ creek.
If the road is smooth you don't hear it.
it only is heard mostly on left hand turns.
Sounds like door latch rattle or in the quad door.

Any ideas to tell them??? Anyone had a similar noise?

 

Yea i have some noises! i hate them, when i get to installing some Deadening on the doors hope to get rid or quiet them down!! :o

 

I had this. Noticed that when i closed the front door, which obviously latches to the rear door, it would bounce back a bit, especially the bottom. Adjusted the door at the hinges (latches and strikers are not adjustable), no more problem.
