Just fill it up to the hole, or close to. I have never seen a diff filled to the hole that caused a problem. If you are worried simply drive it, and while it is hot pull the plug and let any excess run out.
Rear Differential Fill Level Question
Any tricks and tips for not overfilling my 2003 Sierra 1500 Z71 rear differential fluid. The factory recommendation is to fill 5/8" to 1 5/8" below the fill hole when the oil is cold. Thanks for sharing your wisdom.
