Power Transfer Unit (PTU) Leaks From the LH Side
If the leak is the red automatic transmission fluid (ATF), the compression seal needs replacement. This is between the power transfer unit (PTU) and transmission. Refer to Removal and Installation of PTU.

If the leak is brown-black, the PTU is overfilled and venting fluid from the top of the PTU. Flash and fill the PTU. Refer to PTU Draining and Filling.
