Do you mean bolt and nut # 2 in diagram?
After removing the nut, you should be able to remove the bolt but at times there are some pressure on the bolt so it would not be easy to get it out.
Reinstall then nut but do not tighten, leave a few threads for the bolt to travel and use a mallet to tap the nut. Some WD-40 on the bolt helps.
Using a jack to support the knuckle assy slightly would reduce the stress on the bolt to allow easier rmoval.
