It could also be a leak from the motor that is blowing back to the differential. I have seen that before especially if you have a leak from the motor.I wanted to know if im leaking differential gear oil?
sounds like your on the right track,,,,,


but ya can also check the level in the diff..


ya should be able to reach your oil level within the first jpint of your index finger,,,, if ya cannot reach the fluid in this reach, add to that point, then recheck regularly ,,,,


also when ya clean off ur diff. place a piece of clean cardboard under it overnite,,if ya got a leak?? ya gonna find drips !!!!!





good luck,,,,,,,,,,,,,,,,,,,,,,,,,,,
if you cant see a leak on the diff. you should pull the wheels and drums off the axle seals could be leaking
some rear end lube is normal, just remove the cover and use black RTV instead of a gasket.
There should be a screw (possibly with a 3/8'; square indentation in it) towards the top/middle of your differential. Open this up, if gear oil comes out then you are full, if gear oil doesn't come out then you are low and should refill until you see gear oil come out of the hole the screw was in. After cleaning the area very well, check after some driving to see if the bottom of the differential is wet, if so you need a gasket.
