Yesterday I decided to change the rear diff. oil. All went well until I came back after the unattended gravity slow fill I was performing. Several oz.'s of fluid ended up on the garage floor because the fill tube had moved out to the edge of the fill hole.... Damn It's hard to know exactly how much was lost, most of it is in, but my question is...... Do I need to drain and refill so I know the exact amount, or is the rear diff. a fill to the bottom of fill hole = full? I do know that it takes 1.3L or 1.4 qt.'s, just wondering if that 1.3L = filled just to the bottom of fill hole w/ the car level?

 

The bottom of the fill hole is the right amount. No worries.

 

I thought so; just checking. Thank for the quick reply. Just have to go clean up my mess today; see how well the cat litter absorbed my wasted Motul.

 

Ouch....but yes, bottom of the hole until it runs out....but not on the floor....lol

 

Thanks. I was a bit reluctant to even share this because it was such a rookie move. I couldn't find my old pump setup, so I just gave it a slow IV from above. The stiff clear tube must of had some "memory" and worked itself out a bit.
