Parts for your 2016 Subaru Legacy-Oil seals

2016 Subaru Legacy oil seals — purpose, care and when to replace

Per Subaru technical sources—including the BN/BS Legacy/Outback Service Manual (2015–2019) for FB25/EZ36 engines and TR580/TR690 CVTs, and the Subaru FAST parts catalogue—this model uses multiple engine, transmission and differential oil-seals. So oil-seals are absolutely relevant to a 2016 Subaru Legacy.

On this car, oil-seals keep lubricants where they belong and stop grit and water sneaking in. They also help maintain correct pressures, so bearings, chains and gears live a long, quiet life. Typical seals on a 2016 Legacy include:

• Engine: front crankshaft seal, rear main seal, camshaft seals, oil pump seal, and sealing at cam carriers/rocker covers.
• Driveline: CVT input and drive shaft (axle) oil-seals, plus rear differential side and pinion oil-seals.

There’s no fixed service interval for oil-seals
