Where would you get a seal for that and would the seal go between the green round part and the plate? Part numbers would be nice too but thats asking for a lot. How easily replaceable is a seal there? I plan on doing my diffs and trans this weekend. I do hear noise from the front axel.

If it is not that and dripping from above what could it be? I plan to wash it well tonight and take a look agian tomorrow to further diag it. IT does seem to be oil colored.

Thanks for the help.
