My hinge has a black plastic color going around the pin, and I have no issues with mine trying to come out, maybe yours is missing this part?
Pivot bushings?
I went with the stubby and got zero radio reception, I replaced it with a flexible one and then just cut it to length so I can go thru garage door without hitting it, at least now I get reception.
no birds but I have been racking up the body count on the small rabbits in my neighborhood.
I think I am over 10 at this point, I don't swerve to hit or miss them I just drive.
They commit suicide under my tires or I hear them bounce off the skid plates, and watch the barrel roll in my rear...
