jackals

Hello everyone - so please I found this forum and pleased to join - I am stuck out in the boonies of Panama and having to do frequent field repair - I am seeking advice and direction on a new saga with the old devil - when front wheel is jacked up off ground there is lateral movement of about 1/2" on that wheel - I am assuming the wheel hub needs to be tightened??? Anyone have advice if this is the case and how simple is tightening up the wheel hub with basic field tools - thanks...
