chris king inset 1 (sealed bearing) serviceable?

[LGavin]

Hey guys,is it possible to clean up a sealed bearing headset like the chris king inset 1? I thought a sealed bearing type of component is service free..been having creaks in the headtube area for quite some time now. Thanks in advance!

You probably already found your answer, but King bearings are serviceable.
