on the front diff there is a fill plug (should have a square hole for a retchete drive) you remove the plug and the fluid should be level with this hole. the tranfere case is the same but there migt be 2 plugs use the top or the higher of the two for the fill as the lower is the drain......mike

For my 8.5" 10-bolt rear diff (I don't have 4wd, so I'm not 100% on this), the aformetioned plug is on the passenger side of the diff on the front part near the driveshaft yoke. It's a fairly large plug, so ou shouldn't miss it....
