Cause:

Remedy:

Sealing with black sealant (Loctite 5970) only if there is definite droplet formation in the vicinity of the seam or in the vicinity of the propeller shaft to the front axle transmission.

If the problem is a "sweating" leak, sealing must not be carried out, as this is a normal phenomenon inherent in the design of oil-filled systems.

In accordance with the WIS instructions in the attachment, disassemble the transfer case housing and seal it using black sealant A003 989 98 20 (Loctite 5970).
