      Simply check the depth (at the end of the axle housing) of the hole where the bearing fits. Then, measure the width of the bearing to be installed. If the depth of the hole in the housing matches the thickness of the bearing, you can go without the spacer. But, if the depth of the hole is deeper than the thickness of the bearing to be used, install the spacer. But, this part National Ball Bearing, part number RW-607-NR manufactured by National has an integral heavy duty seal that faces the differential side of the axle. The specification of this part: Ball Bearing; Bore: 1.378", Outer Diameter: 3", Width: 1.425".
      For compatibility of this part with your vehicle, please provide your vehicle make, model and engine specification.
