Parts for your 2014 Subaru Forester-Thrust bearing

2014 Subaru Forester thrust-bearing

Based on technical references including the Subaru Forester SJ (2014) Service Manual (Engine and Clutch sections) and Subaru parts catalogues, a thrust bearing is indeed relevant to the 2014 Forester. There are two contexts: every FB-series engine (FB20/FB25) uses a crankshaft thrust bearing integrated into the main bearing set to control axial endplay, and Foresters fitted with a manual gearbox use a clutch release bearing, commonly called a thrust bearing in Australia and New Zealand. CVT models don’t have a clutch thrust bearing because there’s no manual clutch to operate.

For Foresters with the 6‑speed manual, the thrust (release) bearing sits on the gearbox input shaft and presses against the clutch pressure plate via the release fork when the driver pushes the pedal. Its job is simple but critical: let the rotating clutch assembly be disengaged smoothly while the pedal force is applied. When it’s tired, you’ll often get a growl or chirp as the pedal is depressed, a notchiness in the pedal, or inconsistent clutch take-up. Subaru’s service information treats the release bearing as a wear item, best replaced whenever the clutch is out.

Replacement is straightforward workshop practice but worth doing right. The most reliable approach is to install a complete clutch kit (disc, pressure plate, thrust/release bearing, and pilot/guide bearing) so all mating surfaces wear together. Whilst the box is out, check the release fork, pivot ball and the input shaft snout for scoring. Lightly lubricate the snout and fork contact points with a suitable high‑temp moly grease—sparingly—so the bearing can slide freely without attracting grime. On hydraulic setups, bleed the system and ensure there’s no pedal preload that could keep the bearing riding on the pressure plate all the time.

Good habits make a difference. Avoid resting a foot on the clutch, don’t hold the vehicle on hills with the pedal, and use neutral at long lights—those small changes stop the thrust bearing from spinning unnecessarily and add kilometres to its life. Most owners won’t have to touch the bearing until the first clutch replacement, typically well past 100,000 km depending on driving style and load (towing, steep terrain, city traffic). For CVT owners: there’s no clutch thrust bearing to service, any driveline noise should be diagnosed within the CVT or ancillary components. The engine’s crankshaft thrust bearing is internal and not a routine service item unless there’s bottom‑end work or abnormal endplay.

• Common signs of a worn thrust bearing: noise only when the clutch pedal is pressed, rough pedal feel, and inconsistent engagement.
• Best practice: replace the thrust bearing whenever the clutch is replaced, inspect related hardware, and set correct pedal/freeplay.
• Technical references: Subaru Forester SJ Service Manual (Clutch and Engine sections) and Subaru parts catalogues identifying the release/thrust bearing and FB engine thrust bearing.

Popular questions

Does a 2014 Subaru Forester with CVT have a thrust bearing to service?
No clutch thrust bearing is fitted on CVT models because there’s no manual clutch. The engine still has an internal crankshaft thrust bearing, but it isn’t a regular service item and is only addressed during engine rebuilds or if abnormal endplay is diagnosed.

What are the symptoms of a failing thrust (release) bearing on a manual 2014 Forester?
Most commonly, a rumble, chirp or whirr as the clutch pedal is depressed, sometimes with a slightly notchy pedal feel. If the noise disappears when the pedal is released and returns when pressed, that points strongly to the release/thrust bearing, not the gearbox input shaft bearing.

Should the thrust bearing be replaced every time the clutch is done?
Yes. It’s standard practice to fit a full clutch kit—disc, pressure plate, thrust/release bearing and pilot/guide bearing—so everything beds in together. It costs little extra in parts compared with the labour saved by not having to pull the gearbox again later.
