Thanks rebeldad that makes sense I was thinking of the same thing because if it’s filled by the front axle it should start coming through the reduction housing that would make the most sense and be the safest knowing that it’s filling up the reduction housing also
Hi I went to change my front differential case and final reduction gear case oil first it tells you drain your axle differential oil and Fill to lower end mark on dip stick
Then The manual said remove each drain plug from each reduction gear case after the oil has drained and filled reinstall...
