So today I went driving into town, and as I went to pull off I heard this terrible rattling noise......so id stop and itd do it again when i pull off.....I got out checked and banged on a few things and nothing.....seems to be coming from the rearend. doesnt do anything when going in reverse just pulling off until I shift into 2nd......any ideas?

 

Does it sound like a heat shield (piece of tin/aluminum) near the exhaust rattling?

 

i havent been able to have anybody else drive while I listen.....i know its from the back.....the best i could do was stick my head out the window....my truck has a rattle in the leaf springs but this isnt like what ive heard....only when im pulling off in first.....im praying my gears are okay....I dont drive crazy or anything and I havent gotten any codes or check engine light

 

An 07 should still be on warranty - go have the dealer listen to it.

 

so i pretty much think I found it, got to the house today and since it wasnt raining(thankgod) I opened my door to see if i could hear it with the truck running....moved forward and back a few times then put the e-brake on and could still hear it, crawled under the truck and hit a few more things but could still hear it......but finally I listened and listened and finally found the sound........apparently my dual exhaust hanger in the back has come loose and everytime I go to pull off its vibrating against it making the noise...soooo looks like I just gotta get it welded back into place and ill be good :-)

 

That certainly isn't covered by Ford warranty - but it should be covered by the exhaust shop's warranty.

 

i know its not covered by fords warrenty, i know the shop that I took it too and im goin this weekend to get it welded back up

 

Glad you found the source. Noises like that get on the nerves real quick.
