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

sounds weird but maybe check your rim tape-if it's the cheap nylon strap stuff it could squeak/be making a loose spoke hole eyelet squeak? Whatever it is sounds fairly macro-I had silly lightweight q/r skewers that clicked and did my head in for ages.

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
