Rear Phil FSC Freehub - Clunk... Clunk... Clunk!

Phil was nice enough to provide a new freehub body under warranty. This got rid of the noise for about 1500 miles. The noise has recently returned so I disassembled the wheel and cleaned and re-greased the assembly. While apart and clean I could readily see areas on the ratchet teeth where the pawls had been slipping i.e failing to engage the ratchet ring. On a ride today the noise was still there. At this point I am assuming that the ratchet ring needs to be replaced. Does anyone know if this can be done by a mechanically inclined individual or an experienced LBS? I am assuming that it might require special tools? This is my first experience with Phil hubs and I am really disappointed concerning their reputation for quality products. Is this the kind of mileage that I can expect from one of these hubs? Is this freehub design just finicky? i.e. if the moon, stars, and special grease viscosity all line up then they work properly. If not they begin eating themselves up in short order? I have noticed that even fully greased the pawls seem kind of "jerky" (not smooth) when pressed by a finger. I wonder if this is the same thing that is keeping them from fully engaging while in the hub. Should a special kind of grease be used on these? Thanks for any insight. An uncommon situation with that hub. *Not being able to see it, my thoughts are that your lubricant is too thick. A very thin grease maybe, but we prefer a gear oil on pawls. You should consult with your local Phil dealer or call Phil Wood. I had trouble with pawls not engaging properly using heavy gear oil (80w-140) in a Mavic hub. After the pawls slipped a few times the edge had worn off them and I reshaped them carefully with a file. Now I use much lighter oil (ATF), and have no problems. JS. I use Mobil One..0W-15....doesn't get thick in the cold either, cheap as well. |

Is it just me, or does it sometimes seem that some of these things become fussier and more of a maintenance hassle the more exorbitantly you pay for them? Chris King and Phil Wood, I'm looking at you. With the cheap and effective stuff, I've never found myself worrying about what lube is on the freewheel pawls or whether the stem has been faced on a lathe. Chalo |

Steve 3/15/11 UPDATE I spoke to Mark, the service manager, at Phil Wood & Co. today. He related that the freehub and ratchet ring were not manufactured by Phil. I guess that is not a big surprise since most Phil products are CNC lathe intensive. He said that they had gotten a run of ratchet rings that were not properly hardened leading to premature wear The wheel is on its way tomorrow to sunny California. Steve |

A heat treatment and/ or a material problem. Whether produced in house or out sourced material (steel or aluminum or whatever) has to be checked for hardness. Some parts must have slipped through. I would think they have a Rockwell hardness tester. However there are hardness testers that test the material closser to the surface. In my job I worked w/ steel fabrication, one of my more common statements was something to the effect: “Everyone makes mistakes, what really counts is how they correct the error, & whether they try to correct it rather that hide it or try to pass it off as correct.” I wouldn't rush to judgment that Phil is no longer a high quality co, JD |
