Freehub Bearing Replacement

I own, have used, and can endorse the type of ebay tool linked to above too. Much easier than trying to punch and drift it out.

Exactly so, works a treat.

There are tools on eBay that lock into the two cutouts and are secured by a long bolt right through the hub.

which two cutouts do you mean? Any pics?

The cup has two cutouts for the dogs of a TL-FH40, a very rare and expensive tool. Alternative tools that do the job better come with a long bolt, washers and a wingnut to stop it slipping.

thank you, presumably you did not notice that I made the earlier comment conditionally, on the basis of the OPs
freehub being a campag one, or my later reply when I realised that you (and the OP), probably meant a shimano-style hub. IME all such tools suffer from the fact that the drive dogs are part of the thing and cannot be replaced. My tool design (which I came up with ten or more years ago) has no such disadvantage.

For £7.29 including postage, a bit of dog wear should be acceptable in a tool used once or twice per lifetime! A bike shop frequently overhauling freehubs, if any shops will touch such work, might want something better.

as I mentioned, I have used my tool hundreds of times and yes,I have had to replace worn drive dogs.
