Default Any site to diagnose problems?

Sheldon Brown's site is all well and good, but I often have a problem diagnosing the fault. Is there
a site which gives descriptions of problems to allow me to diagnose?

Basically, the bottom bracket is making an irregular noise that sounds as if the bearings are dirty.
It's a under tension problem only.

If it's not a cartridge unit strip it and check it out. If it's a cartridge unit remove it from the
bike, place it on a bench or table, hold the cartridge then revolve the axle by rolling the side of
your hand on it, one side at a time (the axle:-). The table/bench will act as a sounding board
amplifying any naughty noises. If there are any the unit most likely needs replacing.

In my experiance it is possible to diagnose without removing the bottom bracket, remove the cranks
and turn the spindle between fingers. Any irregularity or stiffnes replace bottom bracket

Other sources of noise that can be confused with bottom bracket

Pedals, why do I always wear out my right hand side pedal Seat post and clamp, last week I had a
noise that I thought could be the bottom bracket eventually traced it to a slightly loose seat post
to seat clamp. By slightly loose I'm talking about quarter of a turn with a six inch allen key

Beware a well maintained bike should not make any strange noises, be it clicking,creaking or clatter
from the driveline. Things do not get better they eventually fail, frequently miles from home
