What's the difference between 漏油 and 滲油

Can you give me a hint?

If I remember correctly with my pathfinder case, the oil actually went into the drum brake area. So I guess
漏油 means see a lot of oil in brake while 滲油 is just a little amount of oil? Is my guess correct?

Regarding to the sway bar link, I am afraid this seller
would not allow me to open it even if it is a quick disconnect.

But what's the point to disconnect sway bar and climb
on a little rock? Will it help me to find if the axle has any problem, or it will help me find problem with
the body sway?

Also, just curious about the axle problem, when you said axle is the first one to break before transmission, T-Case, does it usually break in the middle of the axle, or just break the threads that
is used to receive torque?
