Shimano Hubs

[chris__P]

I have a Surly Long Haul Trucker with Shimano XT, HU-M770 hubs.

I'm wondering what the general life expectancy of these hubs is and what I should be doing to maintain them or when I should look to replace them?

Thanks

As long as you are not doing 500 miles per day with a hundredweight of coal on your bike, I wouldn't consider the question!

Keeping the seals free of grit and muck should see all that's required. If you immerse the hubs in a stream, then they would require stripping and re-greasing.
