Parts for your 2019 Subaru Legacy-Oil seals

2019 Subaru Legacy oil-seals

Oil-seals are absolutely used on the 2019 Subaru Legacy. Technical references including the Subaru Factory Service Manual for the 2019MY Legacy/Outback (Engine Mechanical and CVT/Front Differential sections) and the Subaru Genuine Parts catalogue list multiple seals fitted to this model: front crankshaft oil seal, rear main oil seal, camshaft oil seals, oil pump seal, and transaxle/differential drive-shaft (axle) oil seals. These seals keep engine oil and CVT/diff fluid where they belong—inside.

On this Legacy, oil-seals serve to prevent leaks at rotating shafts and housings. In the FB-series engine, the front and rear crankshaft seals keep engine oil from escaping at the front timing cover and the flywheel/torque converter end. Camshaft oil-seals keep oil inside the cam carriers. In the Lineartronic CVT with integrated front differential, axle oil-seals prevent CVT/diff fluid from seeping out around the driveshaft stubs. When they harden with age or heat cycles, small weeps can turn into messy leaks that drip onto undertrays or hot exhaust components.

Oil-seals aren’t a time-based service item on the 2019 Legacy
