You must continue to set the lube level by filling the diff through the original hole on the side of the diff housing. The small plug in the Ex cover is set up for the IRS diff which can get by with a lower fluid level.
If you set the Ranger fluid level using the Explorer rear cover fill hole, your axle lube will be low and may starve the outer axle bearings. An 8.8 Ranger diff should take about 2.5~2.75 quarts of lube filled to the bottom of the diff housing fill hole.
