Clunking/rattling sound under dashboard

[Steven Muraoka]

I have searched repeatedly, but still cannot locate the annoying "clunking" sound coming from under the dash. The area where I think the sound is coming from is near the parking brake. It sounds like a loose bracket that rattles around whenever I drive over bumps in the road.

I have checked for the loose screws hidden under the knee pad that people have suggested here, and found they were all tight. I placed a wrench just about any fastener I could find, and they were all tight. I checked on the top of the dash near the light sensor and all appeared good.

Can anyone suggest checking somewhere that I may have missed? I appreciate any wisdom you guys can share. I have searched this topic on these forums and went through most of the suggestions there. Truck is a 2017 DC. Thanks!
