A few questions regarding rear axle
1. Other then vent line, where to put oil in to differential?

2. Can a differential bearing be replaced without having to take entire assembly out?

I was going to replace wheel bearing and seal after having somebody else re-seal the differential cover;
when I got the cover off, there was no oil in the housing and also noticed one bearing worn enough for rollers to fall out

Fill plug 3/8 square on front of DIFF housing ie. Drive shaft side at level of axle tube. Will need to remove chunk to replace bearings. Suggest a profesional do this or replace DIFF with bone yard one.
