Loose weight on frame

[Morgasm11]

I was backing out of my driveway the other day & noticed a clunking noise when going over a small bump. Turns out the weight on the drivers side of the frame is loose. Will the bed need to be removed to access the nuts to tighten it back up? Also, how many weights are located on the rear of the frame as this is the only one I've found (didn't hunt hard).

Sounds more like the NVH dampener. Might as well throw it away.

Actually that weight moves back and forth so it is loose per say. Its on a rubber bushing so it might not of been what you heard.

Rears have movement on both my '13s

I noticed the same weight, rubber dampeners or not, it still makes noise and the question is what is it for/why is it there?

The rubber dampers deteriorate and it will flop around.
I removed the one on my truck a long time ago.

it's suppose to help with vibrations

There is a gazillion thread on this already. Search for Dampner or Rear Weight. Bunch of hits....here is "just" one.
