Whenever I drive on the highway something starts to rattle in the right front of the truck. Anyone know what it could be??

 

Don't have a clue, perhaps another hint? Am not trying to be a jerk (thats a given) is the rattle, a tinny sound, or or a heavier sound, or could it be an engine ping? Pinging isn't that common in todays vehicles with the computor controls. Just remembered, what are you driving? Been a mechanic my whole, life not a shrink.

 

its a 05 f150 supercrew and its a heavy sound. It only happens when im going 50 or faster
