Assuming the leak is on the inside tire, touch the fluid with your fingertip and smell it. Light sulphur smell it's diff lube, anything else it brake fluid...if you have hyd brakes. If the leak is on the outside tire then it's diff lube from the axle drive flange, easy to fix and not a major safety issue.
I have a slight leak in my left seal that only appears if I level using a board under the outside dual and then only rarely. Mine is diff lube.
