Seizing freehub

[kylemalco]

I have an approximately 10 year old dawes giro 500 that I have never really used maybe 400 miles since new, have started to do a bit of mountainbiking this past few years and this year have a colleague who does a bit of road cycling and asked me to join him. The past few times I have been out the gears have been snagging and locking and jumping on the rear cassette, I found a really good guide to get the gears adjusted, part of the problem being the top jockey wheel was too close to the cassette and the derailleur was hitting the teeth of other gears.

The freehub is definitely seizing there is a slight squeel when freewheel and sometimes it locks up. I have had the cassette of and the cones but the axle is unthreaded. Is it ok to tap it out with a mallet if I have the hub well supported and any tips for fitting it back into the exact right place. Also I was going to replace the old freehub with a 8/9 speed tiagra freehub how do I know if this will be correct, The shifters, front and rear derailleurs and cranks are all tiagra 9 speed but the hub is quando so is it ok to assume that the freehub would be tiagra, please excuse my ignorance have tried to explain this to the best of my ability.

Any help would be greatly appreciated

Thanks
Kyle

When you've removed the quick release, axle, cones & bearings the freehub comes out with an allen key, usually 10mm if it's Shimano. Just feed it straight in and twist. When it's off remove the rubber O ring from the back (spoke end) and flush everything out with WD40 or similar. Spin it on your finger at the same time, so all the ratchet pawls get freed up. Let it drain a while then pour some thick oil down it, spinning all the time. Car gearbox oil is good but I'm currently experimenting with Molyslip. When it's running smoothly put the O ring back and re-assemble.

Like Heretic says, if shimano, get all the axel/bearings out and remove the freehub with a 10mm hex/allen key.......

Thanks so do I just gently tap out the axle with a hammer

It's a Quando hub (and therefore a Quando freehub). For which freehub bodies are scarcely available if at all. By fitting this rather than a Tiagra hub Dawes were able to save some dosh at the factory. I reckon you'll just not find a replacement freehub bod which leaves only two options, repair it or replace the hub completely. Freehub bodies are not interchangeable between manufacturers btw.

If the hub is squealing it's prob out of grease and likely been run long enough in this state to be beyond repair. I suspect that the chances of it being saveable are v. v. slim. Whats required of course is an internal inspection, repacking with grease and testing. Which brings us back to your enduring question ... Sorry, but without having the hub in front of me on a bench I cannot tell you how to access its internals. Ten year old Quando hubs just aren't all that common and I think you'll be very lucky to find a CCer who is familiar with them.

My advice? Stop wasting any more time on it, bite the bullet and buy a new wheel. Any nine spd will do.

Thanks I was nearly bidding on a new shimano free hub on ebay will pass on it for now. Was out today and did 30miles without an issue after running some oil into it. CRC has a good offer on shimano R500 wheels which would suit me if I need to change
