Hub overhaul - now no clicking from paws

Overhauled my XT rear hub with very generous amounts of Phil Wood

grease got squished up into that area. Anybody ever had this happen?

Should remove the freehub body, flush and then oil it. I use Mobil One.

A sticking pawl, aprticularly when there are only two, can really hurt
if ya break the other one.

I wouldn't worry about it. You might have problems in cold weather if
the grease stiffens enough to cause the pawls to stick. I don't know how
you got grease in there, things are pretty well sealed. You need a big
Allen (10mm) to get the freehub body off of the freehub, you can then
carefully remove the thin rubber o-ring like seal from the back side and
flush/oil around the many tiny ball bearings there, without dismantling
the freehub body. I generally buy rear freehubs when I see a good sale
and use them for parts -- cheaper than buying parts separately, and all
the Shimano stuff is usually interchangeable.

Usually is a big word. Not so for many freehub bodies these days,
particularly for road hubs from shimano.

I used TriFlow, how does that compare to Mobil One?
(Other than being more expensive.)

Much smaller bottle.

(I love TriFlow for little things -- squeaks and creaks mostly; would use
something else for "real" lubing jobs.)

Drippy Bill

reliable scources say the wonderful coasting 10 speed pawl ( or any
pawl)ticking noise tells that there is NOT enough lube on the pawl
surfaces.
phil wood is low viscous when running, less than when out of the tube
and ready for upside down whooops bearings placement

I've had the same thing happen, and I just kept riding with no
problems. The clicking noise slowly returned, but is still pretty quiet
after 2K miles.

I guess the grease gets pushed through the gap between the bearing cup
and the freehub... doesn't seem to be any seal there, since that area
is covered by the outer bearing shield. The grease has a long way to go
to get to the pawls... I thought maybe just having grease pressed
between the freehub and hub was what made it so quiet.

Next time I'll try filling up the freehub mechanism with oil first, and
see if that keeps the grease out... though I suspect the oil will run
out into the hub bearings. I like packing the hub bearings tight with
lots of grease to keep out the water and dirt, but maybe that isn't the
best thing to do...?

I put the Mobil One into a little drip bottle, cheap, lasts forever,
never gets thicker or thinner with temps. But oil is the key, not
grease of any type, for pawls.

when is taking the freehub apart and relubing or replacing the inner
bearings called for on the shimano freehub maintenance schedule?

The answer is never to use grease, only use a few drop of light oil only.
The grease will begin to harden over time, this will cause you no end of
problems.

As common as this knowledge is, I've got to add that I committed the
mortal sin and greased all my freewheels. They now make a much softer
and quieter clicking, almost a "slurping" sound. I find it very
pleasant.

Yes, I occasionally worry about them "clogging" up and no longer
working right. I've worried about this off and on for the past 35
years, when I greased them.
