Hi,
If you are still using the original x-ring black seals this is prob where the leakage is coming from.
You will find that the oil will come out of where the outdrives go into the diff housing.
It's pritty simple to fix and stop and all need to do is change the x-ring seals over to an oring.
Generally a 1/8 shock seal oring works great.
A TD330612 oring is what I am using in mine so maybe give them a go.
Thanks
