Rear Dura Ace hub leaking grease.(4 posts)

I repack my hubs as part of the general upkeep of the bike. Recently I have some issue with the rear hub leaking grease (I use PhilWood grease). At first maybe I didn't put the bearing cup tight enough leaving out some freeplay (I am sure there is no freeplay). So, I put the bearing cup tighter to see if the issue is occuring. IN a way, yes, but not as worst as the other time. My guess is that the hub itself, due to wears, does not seal as well.

This will happen often as most people put too much grease in when they repack. Thje excess will seep out most noticably around the outside of the left hand dust cap. Just wipe it off and keep riding. The more you ride the more excess will be forced out. As long as the cones are properly adjusted and the wheel spins smoothly you have nothing to worry about.

If there is no free play in the cones, there is no need to tighten them further. In fact you should only tighten to get rid of any free play, but not much more. The quick release will compress the cones a little bit when locked down. Sometimes this is frustrating after you think you have it "just right" off the bike.

Hope this helps.

As already said - this is pretty normal (for me, too, anyway) - with Dura Ace, Ultegra, and LX hubs, I have seen the same thing happen (also - sometimes the grease gets into the ratcheting mechanism and silents it, as well - had that happen on my DA and my LX hubsets - the sound does come back gradually, though. I have used the finish line teflon stuff, pedro's syngrease, and regular automotive bearing grease (whatever I have on hand when I am doing the rebuild) with the same results.

Just wipe off the excess after your ride, and you are good to go. (it only does it for a few rides, anyway - then the excess is all out)
