Pajero Owners Club of South Africa

Good day I noticed some oil leaking on my 2005 Pajero 3.2 did where the propshaft goes into the transfer case. I noticed this while I was replacing the rear disc pads. Is this because the rear is lifted on the jack creating an angle or do I have a problem. The ATF level looks fine.

Update
The yoke and seal was replaced this is inside the gearbox/ transfer case rear extention housing . Important to replace the yoke and the seal. If you replace the seal only it will leak again. Pajero on 392 000km yoke is warn and will cut the seal again.
