Yep, that's exactly what it is. It is fastened to the rest of the hub by a hollow 10 mm bolt and you have to disassemble the hub to reach it. Freehub bodies are usually replacement items and are not servicable unless you have a LOT of time and patience.
I cannot even begin to guess what pawls are, and I think of months when u say annular space.
Pawls are little metal tabs that engage "teeth" in the freehub body in one direction to force the wheel to turn when you pedal but pop out of engagement when the wheel turns faster than you pedal or you are coasting. They are what allow freewheels to freewheel in one direction and drive in the other. It sounds like yours aren't engaging when they should.
By "annular space", I meant the little crack between the two parts of the freehub body where you could squirt some oil to try to free up the pawls.
