The main job of the headset is to allow the front wheel to turn. First thing you want to do is loosen your stem bolt. Then take off your bake cables and take your tire off. Take off your compression cap so your forks will come off. Take your retainer bearing out and grease everything up. Once you’ve greased everything put it back together by putting your bearing back in the putting your headset. Then tighten you stem bolts and your compression cap.
