Hey I had done a few searches on here looking for what the heck is still making noise under my truck. I found a thread somewhere that someone said they had a bad body mount or two and it made a loud thud under their feet.
Over the past year I have been working away on my truck to try and rid it of this god awful thud/rattle noise that comes up from under my feet. I am at the point that I have a brand new truck suspension wise and it still makes noise.
Has anyone done body mounts on their truck? did it cure noises from under the floor? is this a common problem to have?
I know everyone says "it's the sway bar bushings" but They have been replaced a couple times just for good measure along with the endlinks other things I have changed/replaced in the 1.5 years i've owned the truck is
-PMF 2.5" shackel/hanger kit and 4" block in the rear with all new bilstein 5100 shocks all the way around
-PMF carrier bearing drop bracket
-Adj. track bar
-front leaf springs
-front and rear sway bar bushings and end links
-upper and lower ball joints
-inner and outter tie rods (all new drag link)
-All new brakes front/rear (rotors/pads and even the hardware using ceramic lube on all the pins)
-New wheel bearing/assembley along with warn locking hubs
-Replaced every U-joint on the truck and had the front shaft rebuilt and rebalanced
-triple disk billet torque converter w/ transgo shiftkit
-6637 air filter and a TW chip
I have retorqued just about everything on the truck, the truck rides smooth and nice down the road and tracks perfectly strait but I constantly hear this popping/thump/hollow crack sound and it drives me insane. it's only when i'm going down bumpy sections of road too (mind you I live in michigan and our roads are garbage!) and when I have friends bounce on my bumpers while the truck is parked it is quiet as a mouse
Holy crap long read there sorry (I just wanted to rule out that I think i've changed/replace/checked just about everything obvious), Anyone done body mounts and experience a cure in noise under your feet?
Anyone know where I can get some body mounts that are better than stock? (poly/energy suspension maybe?)
Thanks for any ideas/info, Maybe I just need to buy a FOR SALE sign
