Metallic ticking noise Ford Ranger?

I have a 90s ford ranger that is making a pretty loud, metallic ticking noise.

When I first start the vehicle and shift to either drive or reverse while idling, I can hear the ticking, I don't hear it when in park.

As I lightly step on the accelerator, the ticking increases in frequency until I reach speeds of around 30-40 mph where I can no longer hear the ticking noise. After driving for a few minutes at these speeds and idling again, the ticking noise does not occur. I will only hear the ticking again when I restart the vehicle a little while later.

Anyone have any idea of what this might be?
