can my bolts be broken ? my bed shakes pretty bad over big bumps ( we have a lot in NJ ) where are they located ? I got a haynes and it does not have a break down of the bed and bolts that holds it in place

If I remember right there is 8 bolts all from the underside of the truck... ISX just got done doing it he could tell you quick...

They are just about 1.5" long screws, no nuts. They are very easy to get to with a long extension. They should all be 15mm.Those pictures are of one side, the other side of the truck has the same bolts. The back bolts are on the inside of the frame and the front bolts are on the outside.

Thanks ISX I knew your the go to man for this...

My QCSB has six bolts. As has been mentioned, they are easy to access. The front two mount through perches that are a little flimsy. One of mine had cracked. I welded a big washer onto it and it's fine. Other than that, the frame is pretty flexxy on my truck and the cab and bed seem to move independently of each other.bb

you got that right...75mph down the free way with a full ladder rack makes the bed move around a lot! i never notice until a couple months ago, when i rode in the back seat. i was worried so i check at the next rest stop and all the bolts were present and tight.

I can see mine move side to side over railroad crossing over 30mph

i had a standard cab and had the back window open. had my arm outside of it with my thumb kind of between bed and cab and got scared crapless when it flexed! didn't pinch it, but holy cow! was close!

Here's a pic of my truck through some articulation mounds. It is a crappy shot but you can see how the body lines are off. The holes under th right rear and left front are deep enough to hang me up there. I had to put a rock under the LF tire to get out of the hole. So, that's about as bad as it will get... The good news is that the added flex in the frame makes for better overall articulation in these types of situations.

Here's what the rear looked like:
