ID what this is!

So I was under the rear of the truck laying down some fluid fill on the frame for some winter rust prevention and notice this chunk of metal with 2 rubber boots sitting on top of the frame on the drivers side close to the rear bumper area. It moves freely but is conneced at the frame. No clue what it is or its intended purpose...someone school me!

Back in the mid 2000’s, there was an issue with trucks (not just Ford) with an empty bed shaking or bouncing at highway speeds. This vibration dampner was designed to offset the harmonics of that occurrence at first as a resolution (TSB) to solve the issue for those that presented the problem to dealership then Ford continued to use the solution in future production years.

I thought it could be a Whatchamacallit but it also looked like a doohickey.

I believe it is referred to as a thingamajig in the ford reference material.
