Can BB bearings be greased? I have a tube of Park Tool PPL-1 Polylube 1000 Grease.
It could be your pedal bearings as well, but IME you feel that but don’t tend to hear it. I don’t remember if you listed your crank type, but I’ll assume it’s square taper for now. A picture will clear that up. If it’s not self extracting (typically an 8 mm allen) then you’ll need a crank puller. Not hat to use and not expensive, but it is critical the tool be fully installed by hand and used properly. The threads inside cranks are especially easy to strip out, in a not so reversible sort of way.
Cartridge bearings (at least the ones on my older Davinci) can be regreased, but once the bearings are crunchy it’s better to just replace them. Todd sells them as a spare part, but they are a common bearing. Just don’t replace them with the junk on Amazon.
