bearings in steering neck

I have a 53 Schwinn Panther, Bought it already restored and do not know too much about some of the components. My bike has a terrible squeak in the steering when I ride. What is the safest way to inspect/grease these bearings? Dont want to jack up my paint or chrome. I have a 52 girls panther Im going to restore but have a project to finish before I start another. Any help would be great.
