Bike noise, creak, click, creaks, clicks, clicking, pinging sound - help

Removed the rim tape which was the fabric variety. All eylets and the weld look to be fine there was a lot of what looked like salt under there, presumably from winter.

I cleaned it all up slapped on some new rim tape, again fabric, pushed the bike back into its home and there it is again, "ping". Aaaaarrrrrggggghhhhhh.

Should I be lubing the spoke nipples or bashing out the bearings and replacing? If the latter can I determine the required bearing before bashing out - it's an unbranded hub?

Thanks everyone

This 'ping' if it is a true ping, like a spoke ping but not a spoke ping as spokes are all seated and tied. Could be spokes overlapping and rubbing / releasing on rotation. Solder / wire at overlap will stop this. You are sure it is not mudguard catching? I had a loose bolt on mud guard causing noises.
