Parts for your 2017 Subaru Forester-Cluth slave cylinder

2017 Subaru Forester cluth-slave-cylinder: do you need one?

Short answer: no. For the 2017 Subaru Forester (SJ series), a cluth-slave-cylinder (clutch slave cylinder) isn’t fitted or required. Subaru’s own service information for the SJ Forester and the OEM parts catalogue for MY17 show two setups only: models with Lineartronic CVT (which have no clutch pedal or hydraulic clutch hardware), and manual-transmission models that use a mechanical cable-operated clutch—not a hydraulic master/slave system. This is consistent with workshop manuals and OEM/EPC listings that provide a clutch cable and related hardware, but no clutch master or slave cylinder for 2017 Forester trims.

Why it’s not used comes down to the driveline design Subaru chose for this model year:

• CVT models: No conventional clutch assembly is used by the driver, so there’s no slave cylinder to service.
• Manual models: The Forester’s manual clutch actuation is via a cable, so there’s no hydraulic circuit and no slave cylinder on the bellhousing.

Some owners spot “clutch slave cylinder” listings online and assume it applies to their Forester. Those are typically generic results for other Subaru models (e.g., WRX) that do use a hydraulic release system, or for different years/platforms. Cross-checking against Subaru’s workshop literature and the official parts catalogue for the 2017 SJ Forester confirms that a cluth-slave-cylinder simply isn’t part of this vehicle’s bill of materials.

If the Forester is manual, the practical maintenance focus is on the clutch cable and related linkage:

• Inspect pedal free play and adjust to spec if needed.
• Check the cable for fraying, stiffness, or a notchy feel, replace if worn.
• Ensure the firewall grommet and cable routing are intact to prevent water ingress.
• Lubricate contact points at the pedal and release lever where specified by Subaru procedures.

No clutch fluid changes are necessary because there’s no hydraulic system on this model. For CVT variants, follow Subaru’s CVT service recommendations instead, as they’re entirely different to a manual clutch setup.

FAQs

Does a 2017 Subaru Forester have a cluth-slave-cylinder?
No. CVT models don’t use a driver-operated clutch at all, and manual models use a cable-operated clutch, so there’s no hydraulic slave cylinder fitted.

How can an owner confirm what their Forester uses?
Pop the bonnet and look above the transmission: a hydraulic setup would have a clutch master cylinder and fluid reservoir at the firewall and a slave cylinder at the gearbox. On a 2017 Forester manual you’ll find a clutch cable instead, and CVT cars won’t have any of that hardware.

Why do some parts sites list a slave cylinder for this car?
Those are usually generic Subaru listings or for other models/years that use hydraulic clutches. Checking the 2017 SJ Forester workshop manual and OEM parts catalogue shows no clutch master or slave cylinder for this model year.
