trials owns Posted September 7, 2010 Report Share Posted September 7, 2010 (edited) hi there, my hub keeps going wobbly, its a cheap onza open bearing one, it was wobbely then i took it to the LBS and it came out nice and smooth without no wobble, the day after it started wobbling ( was doing basic stuff) so i tightened up the cones.its ok for a short while then starts going wobbly so i tightened the cones up again ( done this 3 times when it got wobbely) but it still wobbles badly, what should i do?, just keep tightening it up when it does wobble? its pack full of grease. so any ideas on what to do? exept get a new hub which im getting soon. the chain was nice and tight but i dont think it was that tight to break the bearings. cheers oh and sometimes it only wobbles in certain parts of the wheel, always in the same place and other parts of the wheel its nice and sturdy. EDIT sorry if i have repeated wobbles or wobbly so many times Edited September 7, 2010 by trials owns Quote Link to comment Share on other sites More sharing options...

Had this problem before also... on the outside of the cones (away from the hub) there is a little locknut. It should need a 17mm spanner, tighten your cones to your liking, then tighten the locknut VERY tight. When tightening the locknut, hold the cone with another spanner so it doesnt move while you tighten the locknut. Do this to both cones. If it doesn't work, i would suggest buying a sealed bearing hub, as you seem to have alot of problems with your wheel wobbling etc. and sealed bearings are amazing compared to cones in my (and possibly most others?) opinion. EDIT: Did you ever check if your axle had snapped? Hope I helped mate. Edited September 7, 2010 by modifiedridah2k9 Quote Link to comment Share on other sites More sharing options...
trials owns Posted September 7, 2010 Author Report Share Posted September 7, 2010 (edited) sweet, that might be the problem will try it tomorrow, cheers EDIT is the lock nut inside the silver nut on the hubs?, hear the one that i have http://www.tartybikes.co.uk/product.php?product_id=103&category_id=62 i have been tightening the silver nuts so it doesn't wobble. (not the axel one that tightens on the frame ) Edited September 7, 2010 by trials owns Quote Link to comment Share on other sites More sharing options...

Yeah, the locknut is the silver thing. You may be tightening it without holding the cone still with a 15mm spanner? If you arent holding and keeping the cone in place it will just move again, and the locknut has to be like the wheel bolt, extreme tight. This may not be the problem, but its sounds like what i had, which was fixed by doing this Quote Link to comment Share on other sites More sharing options...
trials owns Posted September 7, 2010 Author Report Share Posted September 7, 2010 (edited) ah cool, i was just screwing the locknuts in ( while holding the other one with another spanner, so thats not right?? i have always done that though)in so it was ok but then goes again, so i need to get the cones at the right place which is the bit before the locknut?? then tighten the locknuts really hard u say? i thought that the locknut pushes the cones in to stop the wobble. cheers for the help and sorry for the really noob question.

Yeah the bit on the inside of the locknut is the cones, and hold them whilst tightening the locknut. Quote Link to comment Share on other sites More sharing options...

ellingtj Posted September 8, 2010 Report Share Posted September 8, 2010 It may also be worth having a look at the bearing surface in the hub, as this has been known to crack on some Onza loose bearing hubs (i.e. non sealed bearing hub). But sounds like you're not tightening/locking correctly; however, this design will inherently always need periodic servicing and tightening.
