7k diff fluid should be ok in a buggy, but are the fronts unloading? If they are try thicker fluid. If they aren't check for binding in the drivetrain. No binding, how's the spur to pinion mesh? If that's ok learn to drive smoother. Drive smooth + still hot = find another hobby! Sorry I'm not an expert but i've hit on all the common things to check for. Maybe someone else will chime in and help
