Illustration 2 g00884059 Front axle - The differential and final drives are not equipped with sampling valves. Obtaining an oil sample will require the use of a vacuum pump or equivalent in order to extract the oil from the component. Extract the oil through the filler openings on the differential and final drives.
- Complete any additional required work. Fill the differential and final drives with oil, as required. Install the dipstick/fill plugs.
