When I put on the explorer IRS diff. cover I just fill it with fluid till it reachs the top right??
Do not use the fill level hole on the back of the Ex cover - it is positioned for the IRS diff. Your axle needs a higher fluid level to lubricate the wheel bearings. Instead, use the original fill level hole on the side of the differential housing.
