Fill plug location.

[swamp rat]

On my Eaton Ho52/72 (which ever it is)

I was looking at a pic of before i started working on my truck and the plug is below centerline, i have seen a lot of pic's from this forum also showing the plug in the same position. since then i have also seen pic's of cover flipped 180 with the plug above the centerline..

Looking at a pic with the plug below centerline it sure looks to me that the diff would not have sufficient lubrication for the wheel hubs unless i was constantly turning corners.... I'm questioning if these covers were installed correctly, How does the wheel hubs receive sufficient lubrication of the level is so low it only reaches the bearings during the G force of cornering??

Anybody have a picture/print from a factory manual showing the cover???

Here's 2 links showing both
