Here is Kia Sorento 2005 rear axle differential oil leak video at 64X speed from 1 hour and 30 minute footage.
Now it is repaired by using strong mixture of glass fiber molting method.
Resin alot - twice, let it dry a bit then add putty with strong hardener, let it dry a bit and sanding off unnecessary moisture and finally add couple of lairs thin class fiber fabrics, molt it on differential surface and let it try, shave off any unwanted surface and add some spray color also.
