Some do, some don't, depends on the axle it came with. All Dakotas come from the factory with 75W90, GL5 gear lube in the differential. The limited slip use a friction modifier additive. Mine has the corporate "8" open differential and I'm sure it took a little over 1 quart to fill when I put Mobil 1 synthetic in it. 8" fills to 1/4" below the plug and 9" fills to 3/8" below the plug and there is no gasket. Use RTV.
