Creaks / Groans [sounds ridiculous but gotta ask]

Hey all,
My 2010 Tacoma is the first truck I've ever owned. I have been noticing a lot of squeaks/creaks/groans in the pillars between the front and rear doors [only noticeable with no radio / stereo on, or on but at sub 20 volume] especially when driving at angles over grades / un-level ground [read: speed bumps, sidewalk grades, curbs, potholes, or even climbing over small hills and whatnot at angles.].
I know that a truck has to flex a bit when going over something like this, an extreme case being a twist ditch scenario, but does everyone else's truck make noises like this? I am going to be heading to dealer for an oil change and whatnot soon, and have to get a dash rattle looked at, I was wondering if you guys think I would be nuts to ask them too listen to this noise and consider the causes. Any / all input will be greatly appreciated. Thanks.

 

Sounds like the weather stripping is rubbing and making noise. Take some armor-all wipes to them should take care of it
