Old STX freehub body rattle?

I've got an old STX-RC rear hub I was actually planning to build and ride.

he issue is that the freehub body has a rattle inside. I even took a 10mm allen and removed the piece and it still rattles. It wasn't loose on the hub. The rattle was inside. I popped the seal off and observed the bearings. None were missing. I added grease anyway. It still rattles when I shake it.

My two thoughts are that this is perfectly normal and I am just unfamiliar with lower end Shimano stuff. Or there is a loose pawl. It still works because the other two are engaging. I don't know, I can't get inside.

So do I spend $20+ to replace it on an old hub that isn't worth much? Do I build the wheel and only deal with it if there is a problem, maybe years? Do I cut my losses and just buy a new LX hub for $40 (it appears to be exactly the same).

It's generally suggested that one oils a freehub body, not grease it. Also if the rattle is from the pawls pushing grease into the balls might not get the lube to where the pawls are. Since freehubs (and freewheels) with "loose balls", are designed to have some free play if the internals are dry of lube the various bits can rattle about. I'll usually use Finish Line Wet, Chain L or Phil oils to drip into the body.

Question- Does the body still rattle when all assembled and loaded (as though actually riding)? Andy

Yes it does. That was my first thought.

It's not an expensive part, I just don't want to replace it if nothing is wrong with it.

To be specific a pawl will load up under pedaling pressure and not be able to rattle about it's seating usually. If you've trapped the balls with grease and also loaded the pawls yet still have a rattle I'd want to take the freehub apart to find out what's going on. But mere rattling isn't a 100% sign of a problem. You have the wheel and only you are then able to truly ascertain what's going on or if the freehub has a problem. Andy
