I have a leak coming from a few spots on my rear axle. This is on a 90 lwb montero with a 3.0 and a/t.

One leak is at the pinion and I believe was from a bad U joint/vibration breaking the seal.

The other leak appears to be from the small off center hole in the axle shaft as pictured here

I was hoping someone with experience taking the rear axle apart could shed light on the leak coming from that hole. I am hoping to remove the rear end and change some bearings and seals when the weather warms up and I can use my bike to commute or I get time off from work.
