Welcome abord Joel-

Technically if the bow you own has sealed bearings- they aren't really supposed to require any lubrication...but...

Is this only when you shoot? or when you draw the bow? or both?

white lithium grease is good stuff for axles--just a very little though.

I you do not do your own bow work, I would suggest taking the bow to a competent pro-shop, let them take it apart and relubricate everything/check the axles/cam bushings/limb pockets/pivots/bolts, etc etc.
