Squeaking 05 Durango

My 2005 Durango Limited has a tendancy to squeak upon accleration and deceleration, most times around the 30 mph area. Squeek lasts for a few seconds, then goes away, but happens every time I accel/decel and it only seems to be getting louder. I know it is not the brakes as they have their own distinctive squeak.
Does anyone else experience this, or have any idea what this may be?
