9 Borg Wagner: Oil route to axle bearings ?

Hi,

Does anyone know the route of the oil from the limited slip differential to the axle bearings?

When filling the differential compartment with oil, how does it reach the axle bearings?

Thanks

At about any speed those spinning gears throw that oil everywhere and some will go down the axle tubes to the bearings. Those roller bearings don't need a big flow of that lube.

Also, when the oil heats up it will expand. Iirc, the oil level is right around the axle tubes bottom so when it gets hot it'll make it down the tubes. Also, going around corners will send some down the tubes. They don't need much at all
