If you don't want to spend 30-60 minutes (or even longer if you fail the first time) for the ballon to get to the +3 strength datacron go to the place of the datacron (-3840, -600) directly and bring a juggernaut with you...
Another way is using a powertech who managed to get on the crawler using the ballon may pull you up...
