Have 04 STX that has a excessive truck bed vibration. Nothing in the front end as others have stated. When driving and hit a bump seems to radiate vibration throughout whole back end of truck. Had all four tires repalced by dealer no help. Does anyone else have solution or simular problem?

 

Cross post! See general forum... plenty of replies there...

 

My Bed would shake violently whenever I hit bumps until my line-x was put in. Not sure of the bolts were loose (pre line-x removal/reinstall) or if the rattles are simply less noticable with the line-x. Either way, it is MUCH better now... normal bed shake everyone agrees with.

 

because the frame is so stiff, you are seeing flex in the body panels.

On a cheaper frame, those vibrations would be running through the frame into the cab area.
