Parts for your 2014 Subaru Impreza-Thrust bearing

2014 Subaru Impreza thrust-bearing — what’s actually fitted?

Based on Subaru’s factory service manual for the 2012–2016 Impreza (GJ/GP) Clutch System and Subaru parts catalogues (FAST) that list a “Release (Thrust) Bearing,” the 2014 Subaru Impreza fitted with a 5-speed manual transmission does use a clutch release thrust bearing. The Lineartronic CVT models don’t use a traditional clutch, so there’s no external clutch thrust/throw-out bearing on those variants, any thrust bearings inside the transmission are non-serviceable items.

On manual 2014 Imprezas, the thrust (release/throw-out) bearing sits between the clutch fork and the pressure plate’s diaphragm spring. Its job is simple but critical: when the driver presses the clutch pedal, the bearing allows that push to be applied smoothly while spinning with the clutch assembly, cleanly separating the engine from the gearbox for tidy shifts. A healthy thrust bearing keeps pedal feel light, engagement predictable, and noise to a minimum.

There’s no day-to-day maintenance for this bearing, but it should be replaced when the clutch is out. It’s considered a wear component and is commonly bundled in quality clutch kits. Best practice is to swap it any time the gearbox is removed for a clutch, rear main seal, or input shaft seal job, saving labour down the track.

• Common signs it’s on the way out: chirping or squealing when the clutch pedal is pressed, rough or notchy pedal feel, and difficulty selecting gears when hot.
• Less common but important: a growl that changes with pedal movement can indicate internal wear of the bearing or guide tube issues.

When replacing, a workshop will typically inspect the clutch fork, pivot, guide tube, retaining clip/spring, and the pressure plate fingers. A light smear of the correct high-temp moly grease on the guide tube and fork contact points helps prevent chatter—too much grease attracts dust and shortens life. If there’s oil mist inside the bellhousing, they’ll also check the input shaft seal and engine rear main seal before reassembly.

Good driving habits go a long way in Australia and New Zealand conditions: avoid riding the clutch, don’t hold the car on the pedal at lights, and keep footrests in use between shifts. If a noise appears that changes when the pedal is pressed, it’s worth booking an inspection promptly—catching a noisy thrust bearing early can protect the pressure plate and clutch fork from extra wear.

• Is a thrust bearing fitted to CVT models? No—CVT variants don’t use a manual clutch, so this external thrust bearing isn’t applicable.

Popular questions about the 2014 Subaru Impreza thrust-bearing

How can someone tell if the thrust bearing or the pilot bearing is noisy?
If the noise appears when the clutch pedal is pressed and fades when released, it’s usually the thrust (release) bearing. A pilot bearing tends to make noise with the pedal up and the car in neutral, changing as engine speed changes rather than with pedal movement.

Should the thrust bearing always be replaced with the clutch?
Yes. It’s a wear item and labour overlaps heavily with clutch replacement. Swapping it with the pressure plate and friction disc helps ensure smooth engagement and avoids doubling up on gearbox removal later.

What’s the typical lifespan of a thrust bearing on a 2014 Impreza manual?
It varies with driving style, load, and environment, but many last the life of the clutch. In mixed urban and highway use, owners often see 100,000–160,000 km before clutch-related service, with the thrust bearing replaced at the same time.
