Bed assembly diagram

Hi!
I'm looking for a diagram that will show me the attachment of the bed to the frame.
The problem I'm trying to solve is that the torx bolt that goes through the bed on the front/passenger side of my taco seems to be torqued to the max but if I get under the bed and push it up it seems to have about 3/16" of play. This is annoying driving on uneven terrain because the bed seems to be loose and makes a noise when swinging up and down.
My suspicion is that this bolt was removed by the dealer while performing the frame "recall" and that there should be a rubber washer somewhere in there that was removed. Does anybody have a diagram that could clarify this?
Thanks!

 

I haven't found the 'realoem' equivalent of BMW's parts diagrams for Toyotas, but I know that the dealer has access to that information. Give them a call?

Or check one of the other corners to see what may be missing?

 

Love to. They are closed for Covid until mid january...

 

I thought I recalled hearing that as an issue. The bed rubs the frame and wears down the plastic at that point. Might need a high durometer spacer to go in there.

 

Thks!
It does not look as there is supposed to be anything there. I just don't know where the problem is from then ??? Any idea?
This smells like a deconstruction / figuring things out / reconstruction project...

 

That's what I was thinking of

 

This sounds like the best fix.

I bought one of these at Lowe's recently. It was like an unusually large fender washer made out of hard rubber.

 

Found these on McMaster 5/16 X 2", might be just a weeee bit soft tho.

They have different sizes but this is an example of what I bought at Lowe's.

Sounds exactly like my problem. I will have to work to loosen the bolt though. It seems jammed. And with that composite bed, heat is out of the question. Time and oil I guess...
Thanks!
You guys know everything!
