Rear Differential Fill Level Question

757 Views 15 Replies 8 Participants Last post by  canyon56
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.

Well…did you fill to the hole or 5/8” below???
Now I’m confused. The full hole in the cover is the one you need to measure from for the level.
