Parts for your 2017 Subaru Forester-Oil seals

2017 Subaru Forester oil seals — what they do and when to sort them

Oil seals are absolutely used on the 2017 Subaru Forester. Technical sources including the Subaru Forester (SJ, MY17) Factory Service Manual and the Subaru Electronic Parts Catalogue list multiple seals across the vehicle — crankshaft front and rear main seals, camshaft seals, axle/differential side seals, transmission input/output and drive pinion seals (for CVT/manual and front/rear diffs). These seals are fitted to FB25/FA20 petrol engines (and EE20 diesel where applicable in AU/NZ) and the Lineartronic CVT or manual driveline.

In plain terms, oil seals keep lubricants in and dust, water and grit out. They sit where rotating shafts pass through housings, such as the front of the engine (crank pulley), the back of the engine (rear main), camshaft ends, the CVT/manual gearbox output, and the diff/axle interfaces. Good seals mean stable oil levels and no mess on the driveway
