My experience with old Phil hubs is that even when neglected, and I continue to ride on them, their almost complete lack of viable grease lubrication doesn't prevent their rolling smoothly for many more thousands of miles.

On one such (front) hub, there was a bit of wiggle at the rim, so I tried to poke through the axle and knock the end cap off to get the axle out.
I ended up banging away with a hammer on a QR skewer, even after heating the end cap with smoking-hot torch heat, before giving up entirely.
Then I noticed that the loose bearings and loose wiggle at the rim was GONE, so I resumed riding on that wheel and the looseness hasn't resumed in the past 3500 miles.
I didn't even bother top add grease.
