transmission oil leakage from axle?

[M.T.Pilot]

Hi,

I recently bought an old double cabin pick-up toyota hilux (1989, 4WD, manual). I am not familiar with them at all, as up until now I drove and worked on a toyota starlet.

This morning, I found that transmission(?) oil (clear oil) was leaking from the transmission box underneath the front seats (= called rear differential?). I don't know if this has been going on for some time or that it is something that started recently.

I do know that sometimes, when accelerating, noises where coming from underneath the car and I figured it might be some part of the drive shaft axle.

Anyway, the leakage seems to be coming from where the drive shaft axle goes into that transmission box. But I'm not sure. Also, I do not know what is causing this leakage...

Here's some images:

M.T.Pilot,

It looks like the shaft seal is leaking.
