Square taper BB bearing problems do not show up as a creak or click. Sometimes people come to that conclusion after overhauling one and finding such noise is gone afterward, not realizing that removing, cleaning and correctly retightening the crank arms likely fixed the problem. In fact:
- A worn (or dirty) BB creates a grinding feel/sound, again a lower pitch sound and more continuous, rarely showing up only under pressure, and the BB would not feel smooth.
- A loose BB (poorly adjusted, loose lockring or fixed cup) can be felt as the BB shifts, and if it makes a sound is more like a clunk than a click. Due to the larger parts and interface the sound is a much lower frequency.
- Installed dry (the bearings??) In over 20 years of bike work I've never pulled apart a BB to find it freshly overhauled with no grease. Not even possible with loose balls, and the sound again would not be as described.

This is the correct first step. It's also possible that the cages on the pedals themselves are not secure, though that would be a rare occurrence on both pedals.
We need better info from the OP - not only what he has tried to fix the problem but when it started (new pedals) any maintenance/accident/incident that directly preceded it, and if it came on suddenly or over time. Few problems just spring up spontaneously.
