Hub Grease Question

Wondering what you fellow's use when repacking wheel bearings?
I have been using Park Tool been grease. But I just pull my axle ,as I wanted to replace the seal on my freehub body, and noticed that my recent repack of grease has pretty much disappeared.
So suggestions are welcome!
Thanks!!

I use either Park Tool, Phil Woods or some green marine grease. All work equally well. Not sure what exactly you mean by disappeared. Maybe you just need to be more liberal with amount you are using. Roger

I also use Phil Grease and have never had it "disappear" from any hub even after 8,000 miles or more between overhauls. As Roger noted, perhaps you need to use more grease initially.

I purposely overfill my hubs and let the excess extrude out through the seals for the first couple of rides. That assures the bearings are well protected and the grease itself forms a good secondary seal.

I usually am generous! I fill the race set the balls then cover the balls with another layer.
When I opened it up the vast majority was gone. Time to get a bigger tub of grease!!

Maybe it's just telling you your hubs should be repacked more often.

I've tended to put more than less and just wipe off the overflowing excess.
also over the decades I've noticed that higher end hubs, ie xt type level, have better seals and keep both amount and cleanliness of grease better over time.
so could be amount you put in, how long, and how well hub is sealed.

my guess is amount, but probably combo of all factors

Where does the grease go?

I use primarily use the cheaper Park grease, Polylube 1000.

I've used Phil's green goo for years. But recently I noticed the same Shimano hubs packed in the original Shimano grease seemed smoother, more buttery, like the shearing property was more cohesive. I'm not sure it translates to measurable differences on the road. But I'm tempted to try the Shimano stuff now.

Iíve been using Finish Line Teflon on hubs. I used to use Philís, but now I only use Philís on headsets, non-cartridge bottom brackets, pedals, and any other part I need grease.

I just noticed the Shimano grease is made in Germany.

2 ounces for $10?? I've seen chain lube for less. Much less.

Pass the Pedro's, or the Parks, or the Phil's, or ...

Is it just me, seems to me thicker grease lasts longer. Generally have used Phil's for ages.

I've heard of grease disappearing from hubs... usually from carrying the bike on the outside of your vehicle at 70 miles an hour... maybe the wind did it.
I personally had Phil W grease disappear from a front hub, but I was crossing a creek on foot, using the bike as a prop to keep me from falling in the water and the front hub submerged a couple of times. Next time I cleaned it noticed the hub was gritty..... opened it up and the grease had VANISHED. !!!
Maybe if you are in PNW or really wet areas go for the marine trailer grease.
