This self locking nut is a direct OEM replacement for rear differential service, including differential fluid changes, axle removal, or differential rebuild procedures. Installation requires basic hand tools and adherence to Subaru factory torque specifications. Because rear differential fasteners are safety-critical components, professional installation by a qualified Subaru technician is strongly recommended. Always replace self-locking nuts rather than reusing the old hardware to ensure proper clamp load and thread integrity.
