Be suprised if it was loose they are normally a hell of a fight to change, nut might come loose but the arm is normally well stuck together and heat and hammers or a grinder are required to get it off.. If it is loose i would be tempted to change the arm or at least the Track rod end while it easy..
Been trying to put a Track rod end in mine for days off and on
