Mystery Tacoma Part in my driveway - anyone recognize?

I had my taco in the backyard today and became lodged in some mud. I accessed the rear tailgate to clean out some mud (between bed and gate) can removed one side from the lock pin on pass side. Closed tailgate and got her back on driveway.

After washing her down, I found this small (new looking 1" sealed bearing) under the back side. Does anyone recognize this part? I didnt remove anything except the gate on that that hinge pin for a few mins...but could I possibly have damaged something while getting it out of the mud? Everything seems to drive ok and nothing seems different.

No part number is visible. Thanks for any insight.

 

Is that the muffler bearing I keep hearing about?

Its a fidget spinner bearing

 

Great guess!

That doesn't look like a Toyota part.

 

Whew - thought it was my blinker bearing and was gonna have the 60k done as they were blinking a bit faster.

(thanks - just making sure...I bet it came from my CoolRay Tech - who is a MotoGP nut).

 

Makes your fidget run smoother!

 

From back in my garage door intsaller days. That looks like the bearing that inserts into the torsion spring for the shaft.

 

I bet that's it. I knew I had seen a bearing with a flange like that before.
