Diff fluid level - okay to be level with fill hole

[Adventurebound]

Changed the diffs this weekend and was going to make the little guage others have talked about to make sure the level is below the fill hole and at the mark on the cover then looked at the owners manual. 1/4" +/- 1/4 below the fill hole....or in layman's terms it is OK to be flush with the fill hole.

Thats the way I read it!

When I did my diffs I just filled until it started feeling out the fill hole. Then jusy got a paper towel and stuck it in to soak up a little extra.

No issues here.

Mine's almost level too.

1/4 + 1/4 is 0 to 1/2" so level with the hole is good.

It’s an odd way to explain the fill volume???

I usually rotate the book so I'm reading left to right, but the info doesn't change

I put in refilled the quantity stated by the OEM instead of fooling around with the level business. The nominal amounts were 4.0 qts for rear, 2.0 qts for front.

There - done.

When I removed the plug from my cover fluid started leaking out. The factory must have filled it slightly past the hole. My truck has 21,000 miles.
