95 Jimmy rear diff.

I trying to find out if there is a drain/fill plug for the rear differential. This is a 95 4 door 4x4 auto 4.3 I've looked and tried to find one to no avail, and trying to stay away from removing the cover to do this, as I can't see a way to fill it after I get the cover off and then replace it. Thanks in advance:banghead:

There is a recessed pipe plug r/s of housing above the horizontal casting.

Ayup...there's a fill plug where maxwedge points, but no drain plug. If you had to, you could suck the old oil out with a long tube and pump, but you'll be leaving all the attached metal shavings to the magnet on the inside of the cover.
