lately, when i'm towing my gooseneck, whenever i brake or gear down at low speed, i 'm hearing a creaking noise, like something is shifting around under there that should'nt be. 2001. 5 3500, 6 speed. the sound is definitely coming from under the truck and not from looseness in the hitch. all of our trailers have double walled gooses and holding pins to keep the hitch stable. if anyone has heard or seen a post about this, please let me know. i've got alot of miles to put in this summer... ... ... ...
