creaky
Which bit of a UN55 creaks?
Is your shell straight (coaxial threads, faces orthogonal to the axis)?

I don't really know, but whenever I'm accelerating or standing up going uphill it makes quite a bit of noise.

This is what I assume is the problem - I think it might just be slightly out and stressing the bb (but I have no knowledge of this kind of thing). Is there a hacky way or measuring this?
psb
Are there any decent cup and cone bottom brackets around? Have used UN55s for a while now, but on my commuter bike they only seem to last around 6 months before becoming unbearably creaky. I thought maybe the larger ball bearings in a cup and cone BB would fare slightly better.
