Headstock Bearing Clicking

[dirtsports]

I discovered recently that my headtstock is clicking and has slight movement. I have tightened it up and it's stopped clicking but is this all it will need or will i need to re-grease them too? Is re-greasing easy? are they easy to inspect, how would i go about doing this?? cheers.
