Hey Guys I Just Got My Truck Back From Ford It Had Blown Head Gaskets Its A 6.0 06 With 28000 On It,now When I Hit The Go Pedal It Sounds Like Someone Is Gonna Come Thru My Floorboard,it Dosent Do It When I Let Of The Gas,and Today I Went On A 100 Mile Trip,and The Whole Way Home At 70 Mph It Was Making This Noise,and I Could Also Feel It In The Pedal, Does Anyone Know What This Could Be,oh Yeah And It Does It Stock,or Chipped It Doesnt Matter.

I am sure MARC the site admin would have an answer, BUT my is
As I am sure you know, The Body/cab needs to be removed from the Chassis in order to change headstuds. I would lean towards the possibility that upon re-attachment to your frame rails something was left loose , unattached or pinched. This would explain the noise you hear. Now Drive the truck stock a few days if poss and then take it back to the Stealer, I mean dealer LOL, and have them go for a ride so you can show them.. Either way it's on THEM.
Good luck and let us know whats up....

Could They Have Messed With The Suspension At All Or Not,because Their Is A Slight Miss In My Steering Now For Some Reason.

not every body pulls the cab to do headgaskets , but if they did , the steering rod to gear box does have to come loose , that is the only steering/suspension component that has to come loose , as far as your noise goes almost impossible to know without hearing it

They Did Pull The Cab Of Is It Possible To Mess Up The Steering Rod To Gear Box While Reinstalling,thanx Sheldon.

[SCUFFY828]

i dont think you could mess it up ,but its is possible to have left it loose causing it to feel funny, just take it back and have them check it

Check to see if the downpipe is hitting anywhere. They may not have gotten it ligned up or the clamps could have come loose after a heat cycle and it needs to be realigned and tightened up.

describe the noise...is it a squeek....does it sound like just a bunch of air going through a tight place?? what does it sound like....

Could be a loose Y pipe....an egr clamp at the y pipe or the two bolts that bolt it to the intake not sealing....or a ton of other things....

I highly doubt its related to the body.....if anything that would be a popping noise on accel or decel if one of the bolts was left loose...thats about worst case senerio....

hey marc the sound is a very loud thumping sound , it didnt do it before the shop and now its ridiculously loud,and it does it at all times especially loud at higher mph,then when i shut her down i can feel and hear noise in the steering when i turn the wheel,i dont know if that is where the noise is coming from,but that is my guess.
