Installation

This drain plug is a straightforward replacement during a routine front differential fluid change. Remove the old drain plug, allow the differential fluid to fully drain, then thread in the new OEM drain plug and torque to Subaru's factory specification (refer to your model's factory service manual for the exact torque value). Use of a new sealing washer is recommended at each service interval. No special tools or modifications are required. If you are unfamiliar with differential service procedures, professional installation by a Subaru-trained technician is recommended.
