We’ll show you how to change the oil in your rear differential on a Subaru Impreza WRX! This tutorial suits most Subaru vehicles, as they share the same differential casings and design.
Before starting, ensure your vehicle is level.
- Differential Oil – 0.8L
- 13mm Square Drain Socket (Don’t use 1/2″ tools, it will strip the thread)
AutoInstruct will not be held responsible for damage to your vehicle or personal injury / death as a result of the information we provide.
Using the 13mm square socket, open the fill hole (1) before draining the oil. This ensures we won’t be stranded it the thread is seized
Open the drain hole (2) and drain the oil. Once drained, reinstall the bolt and tighten.
Fill the diff with oil until it overflows back out through the fill hole. Re-insert the bolt and tighten.
