possible freehub issue.

[accountantpete]

Two shops both diagnosed it, I didn't really chase details but possibly bearings were mentioned. Just spun the wheels and the issue is audible, I reckon I might just replace, I'll take for another ride to confirm I'm not happy.

Ah, just remembered one shop did say there was a tiny amount of lateral play with the cassette. I'm sure I've noticed it being there for a long time.

There should be a tiny amount of play in the freehub/cassette as this gets taken up when the skewer is tightened - try tightening up the skewer a bit tighter and see if it disappears.

I've done this following procedure a few times over the years.

Take the freehub off, clean it, then leave it immersed in white spirit or some similar over night. Shake the excess white spirit out of the hub and leave it to dry. Once dry, immerse the freehub in a thinnish oil over night, so the oil drips into the hub mechanism. Wipe off excess oil and test the hub. If the hub sounds and functions ok, then refit to wheel.

[QUOTE 4678637, member: 9609"]just boil the freehub body in a thickish oil, this will clean it all out and leave a nice film of oil inside. I have done this to one that was freezing up and it worked well. I don't think it is a long term solution though as the bearings would probably prefer a grease and you can't pack the sealed design with grease as that would stop the pawls working properly. This freehub eventualy failed when i think the spring broke and the freehub would not come out of drive, which made for an interesting end to the ride - you have to remember to keep pedalling even when braking[/QUOTE]

Interesting idea, I think I saw a rubber seal being taken off by the guy in the shop so this would have to stay off for this process. I think he had to remove the seal to get the freehub of anyway, can't really remember now. I'm buying tools as I need to to get jobs done, I've never even taken a cassette off. What would I need here, a chain whip, I can't remember if he used anything special to get the freehub off though, Any other tools I'd need apart from hex keys, I have them.

Take the cassette off with a chain whip.

Then take the freehub off - try a hex key in the ends of the axle. If there is no hex key slot then the hub fits together with friction - so either try prising the end caps off with a flat headed screwdriver or pop the end in an aluminium vice and knock the rest of the hub upwards.

Not sure I quite get all of that. Removal of axle? I'll be watching some you tube vids later which should help. I watched the mechanic do it all and it looked like he took a plastic cap of the end off the freehub and then used a hex key to remove it. It is a non serviceable type so I assume it doesn't come apart. It was a fortnight ago now so my memory may be confused.

Ok, I've watched a few vids now,,,,blimey, you seem to need a few tools. Chain whip, adjustable, wrench, lockring tool, ok that's the cassette off. Then a cone spanner and a hex key for the freehub. To be fair I can't remember the mechanic using a cone wrench for the axle removal but I was talking to him at the time.

Here we go - in this vid the axle end cap is pushed in and retained with friction - probably like yours. Otherwise you insert a hex key in that end cap and unscrew(try this first!). The internals will be different in your hub.
