This bit looks to be an oil dropper for some components.

I scored a broken Foz box DR to pull apart - so easy compared to MY and L boxes - even though I got covered in an aqua blue water soluble? lubricant
This little box had some fiddle done to its end housing section. Mechanic told me he had to spacer something to make it fit. Turns out he ground the rear end of the shaft that ends in the last section with a bearing.
The nylon dripper thing has been near worn through by contact with another part of the boxes bits - looks like it got caught somewhere it ought not, gave some service life before growling, and back for replacement.
I cleaned out four tips of what look like were gear teeth.
I also expected to see a viscous coupling inside....no ?? found the centre diff in the back section though
