I just purchased a 2003 F-150 Supercrew FX4 with 45k miles. I have noticed a rattle in the mid to back end of the truck every time I hit a bump or uneven spot in the pavement at all. Does any one have any experience or suggestions with a solution to this or at least where I might begin trying to resolve the problem???

Thanks for any help you might have

 

Hi and welcome to the forum

Rattles can be hard to diagnose in real and even harder on here but we'll try.
One thing I've seen quite often on these is the insulators between the leaf srpings worn out. Pry the springs apart a bit and take a look.
