When Should I Change My Axle Fluid? If you inspect your axle fluid, and find it to be thicker, dark or black in color, or milky/opaque, it could be a sign of fluid contamination or break down. If this is the case, it is time to change your fluid. Always use the axle fluid recommended in your owner’s manual or by your vehicle’s manufacturer.
