Rattle, mid-truck

Rattle, mid-truck
97 F-Superduty started to have a rattle out of nowhere. Rattle doesn't start until I've passed about 40MPH, and it will continue until I have stopped. It is speed related, not RPM. Sound is consistent in neutral, with brakes applied, and parking brake pressed. Rear diff fluid is full and clean. My next assumption was the driveshaft carrier bearing. Any thoughts?

I would put a floor jack on the rear diff and get it up in the air to take the load off things. Then see if drive line moves or the pinion seal is leaking or any movement there or the carrier bearing and housing. Also look for any damp spots around the brake drum housing areas. Damp spots will be seals taken out from bearings gone out.

I'm not sure if you will get parts aftermarket. I would disconnect driveshaft from it and spin and listen. I am not there to hear it in person like you are to gauge where it exactly is coming from

Eureka! Found my little rattle problem.
That little ring is just flopping around. Guessing it had something to do with holding the pinion gasket in place, since it's starting to leak.
As for the parking brake, it's been dripping little by little since I got it. Fluid looks like DOT3 and smells likes gear oil.
How-to's and part numbers are welcome.
