Popping sound beneath rear of truck bed?

[Tacorey]

I just got my truck and was walking around in the bed to check everything out. I noticed a popping noise coming from the truck bed, but wasn’t sure what it was. I checked the spare tire, it looks tight. I also looked beneath the truck to see if anything looks out of the ordinary, but I didn’t see anything other than a hole that “might” be missing a bolt but not sure.

I decided to walk around on it some more, and it seems like the only place it happens is near the tail gate in the center. It sounds to me like the bed is bowed up, me standing on it compresses it down, and the pop sound I'm hearing is from it unsticking from whatever is below after the weight is released. Is this normal? It’s similar to a hardwood or laminate floor where there’s a tight area that bows up a bit, and when you step on it, it makes a pop/unsticking noise after you remove your foot.

Will do. Might try to take it to the dealer this weekend. Do you have the spray in liner?

No just the regular composite bed

Okay, mine came with the spray in, so doesn't seem like it's related to that. My guess is a bed alignment/bed binding issue. I will update when I get a chance to get it checked out.

Any of you guys have a service coming up where you could ask them to look at it?

I have the same noise on a 6ft bed. I crawled underneath and noticed, it looks like the bed just has a locating tab sticking through rear cross rail in that spot and possibly does not have a fastener or at least never has had a fastener. I'll mention it to the dealer during my first service

I believe it’s just the bed liner bending and snapping against the composite bed. I don’t believe it’s truly a spray in liner that permanently bonds with the surface.
