Not sure exactly where a rattle is coming from but only hear it on major bumps or patchy roads. Sounds like door, supercab door or bed when I go over bumpy areas. Only drivers side. Just got my 2011 three months ago and sounds like it may have been like that before I got it. Not worried but annoying by times, on bad roads. Any idea where I should be looking or make adjustments?

 

My door rattle in my 2011 was the window lock and door unlock switches. A little padding in the way of a folded up piece of paper did the trick.

To test if you have the same issue, go over some rough roads and hold those switches. If you don't hear it, then that's where it is.

I had a thread for this very same issue a while back...

 

Thank you. Will check it out!
