So funny because that’s exactly what it sounds like! Ha! I’ve even checked the bed of the truck numerous times! ?I got this.....
im an assassin by trade.
when i am peeling away from a call and driving spirited through the streets, i too get the sound when hitting the brakes hard and the body rolls forward and hits the front of the bed.
check for a body in there perhaps. maybe one of my competitors got lazy and did a drive by dumping into the bed of your truck instead of going to the usual construction sites downtown that pour concrete at 2am.
I will check the trailer hitch. I’ve checked the tailgate. It doesn’t move at all. I’m honestly thinking it’s my spare tire and they told me it wasn’t because they probably didn’t wanna take time to check it. They played the ole “we drove it and heard nothing” card. I’m going to take them for a drive.tailgates sometimes thump back and forth.
a damper wont help....at least not when its up and stowed.
and my F150 had a wiggly trailer hitch in the receiver that would give you odd knocks once in awhile.
The latch (black loop) should be on top between the rear passengers and middle headrest.My back seat clunks, very irritating while wheelin' I can't get it to latch shut, didn't know there is a latch. I can't find it yet. I assumed that's the way it should be so I stuck a movers blanket behind it. Problem solved.
Is the rear seat back (crew cab) latched securely?When I put on the breaks there is about a 2 second delay and then I hear a thud! It’s coming from the back of the truck. They tell me my spare tire is not shifting. Can’t figure out what it could be.... any ideas?
No modifications. It’s been making this sound since day one. I’m going to take the service guy for a drive because they say it doesn’t make the noise when they test drive it. ????Try your best to locate the area (may need someone to drive for you). Once you know the area, check for loose bolts or if anything moves oddly. Have you had any modifications in the rear or anything in the bed?
