Dan6061 Posted September 7, 2006 Report Share Posted September 7, 2006 It's the just the freehub you'll have to change, it'll be the whole hub. As the freehub you have is only compatible with the hub shell...I think. Try taking off your freehub, and getting rid of all the thick grease that the manufacturer put on it, and get some fine oil on it.Should stop it skipping.

Dan6061 Posted September 7, 2006 Report Share Posted September 7, 2006 What hub is it exactly?Shimano?Or just some Onza thing?I've only ever taken a freehub off a Hope Xc, and that just came off when I pulled it...Look up a guide on the manufacturer wesite or something?

lil_kial Posted September 7, 2006 Report Share Posted September 7, 2006 Take your wheel off (out of the frame) Take your cassette off (the cogs at the back) this is done by undoing the lockring, the lockring is the round thing with lil notches in it for the tool to fit in, it should be fairly obvious as its end of the cassette (to the right of the last smallest cog) if you dont have tools for the lockring abit of fine tuning with some mole grips (the lock-y kind) can clamp the lockring with enough pressure to undo it but not squash or dis-shape it.After the lockring is off the cassette should come off, sometimes abit of leverage from a screwdriver from behind the first biggest cog will ease it off better .And hopefully (works with most hubs) you should be able to twist the freehub body (the thing with lots of "lines" going down it, that your cassette sits on)...twist it anti clock wise and pull.The free hub body should now be out exposing the rachet (a circluar, ring of teeth) getting a toothbrush in there + sum warm water on it and abit of scrubbing should remove most dirt (therefore stopping you hub from skipping/slipping well for a while anyway) also cleaning the springs and pawls is a good idea whilst your there.Now before putting it all back together you must relube the rachet and springs, grease is a no no something like cross country chain lube is good also GT85 is ok.Putting back together: make sure all the springs and pawls are in ok, getting the freehub back in is hard i find if you push the freehub close/tight to the rachet/hub body and get a small flat ended screw driver to push the pawls down at the same time pushing the freehub back into the body graduall after a few attempts it goes in ok now all you have to do is put the cassette back on and tighten the lockring, and of course but the wheel back in the frame ready for a ride minus the skipping Quote Link to comment Share on other sites More sharing options...

Village Idiot Posted September 8, 2006 Report Share Posted September 8, 2006 Onza Hub - Trials ForumRight, I don't know whether the hub on the T-Rex is the same as the one that was on my old T-Raptor. Anyway, there's some info in the post above about removing and refitting an Onza freehub onto the hub.May be of some use, although I'm not 100% sure.

Village Idiot Posted September 9, 2006 Report Share Posted September 9, 2006 cheers thats good info , did u get ur free hub workin again?Well I got another freehub and fitted that, but it didn't seem as smooth - I dunno if I did something wrong when fitting it.Anyway as the rim was a bit knackered as well, I just ended up buying a new wheel.
