There have been discussions about whether you fill the front and rear diff fluids up to the fill hole, or if you're supposed to fill both up to I think it was 23mm (or 31mm?) below the bottom of the fill holes -- I forget the actual values that were being bandied about.

Has anyone found confirmation from INEOS Automotive on this?

Can someone with access to the online manual (I'm still waiting for access, months now), see if there is a description of the refill process and what those levels should be?

Would like to confirm for the transfer case as well.

Not talking about the volume they're supposed to hold, just whether they're all supposed to be filled to the bottom of their fill holes, and if not, what's the spec?

Specify what MY you have, I think the manuals limit you to just the stuff that's part of your VIN sequence.

thanks!

When I had mine done the tech told me they fill it to the bottom of the fill hole... Done that twice now on mine. Transfer case I didn't ask....
