Whenever I got over bumps, esp. real sharp bumps, like a pothole I hear this metal on metal clank the comes from my bed/rear of the truck each time. I have absolutely nothing back there in the bed at all. At first I thought it might be something with my tonneau conver, but I took that off yesterday and it still make that sound. Any ideas?

 

Make sure the spare tire isn't loose. Remove the tailgate to elimate it as a possible source of noise. Crawl underneath, grab the shocks and give them a shake. Check the bolts that hold the box to the frame. My old '86 F-150 made a clunk that echoed through the bed. Lubricating the leaf springs with spray grease made it go away. Good luck.

 

spare tire hanger loose?

 

Wow - simultaneous posts!

 

Never thought of that....certainly a possibility. I would look now if it wouldn't be 105 degrees outside....haha

 

tailgate
spare tire
leaf spring mount broke
shock loose

 

My exh. pipe/hanger seems to "clang" around when I go over bigger bumps...

That maybe something else to look at...

 

i have the same noise too on my 04, havent really got around to looking at anything, but..

 

My hitch started rattling in the receiver. May want to check that if you have one installed.

 

Mine was doing the same thing. It turned out to be the spare tire was loose.

 

my trucks does the same thing too....and when your driving at 160 kilometers per hour the side panels of the box on the outside flutter in the wind....

 

anyone have an issue with the passenger door rattling on their truck? Sound to me like some weather strip missing, or a latch not closing all the way. Drivers door (s) dont make a sound. This is a standard cab long bed 150.
