2015 Subaru XV thrust-bearing: what’s fitted, what’s not, and how to look after it

Per Subaru technical literature, the 2015 Subaru XV (GP/GP7, FB20) uses a thrust bearing in two different contexts. First, the engine’s crankshaft thrust surfaces are integrated into one of the main bearings, controlling end-float, this is documented in the Subaru Factory Service Manual for the FB20 engine (Engine/Crankshaft section). Second, vehicles equipped with the 6‑speed manual transmission have a clutch release (thrust) bearing, identified in the Subaru clutch system service procedures and the Subaru Electronic Parts Catalogue (EPC/FAST) under the clutch group. XV models fitted with the Lineartronic CVT (TR580) do not use a clutch thrust/release bearing because the CVT employs a torque converter and does not have a manual pressure plate and diaphragm spring, this is stated in Subaru transmission documentation for the TR580 CVT. So, for a 2015 XV: engine thrust bearing is always present, the clutch thrust bearing is fitted only on manual models.

For owners of a 2015 Subaru XV with a 6‑speed manual, the clutch thrust bearing (often just called the release bearing) is the bit that presses against the clutch diaphragm spring to disengage drive when the pedal’s pushed. Its job is to convert the pedal movement into smooth, low-friction rotation against the clutch fingers, so gear changes stay tidy and quiet.

There’s no set replacement interval for the thrust bearing, it’s generally replaced whenever the clutch disc and pressure plate are done. That’s best practice recommended in Subaru workshop procedures and by clutch manufacturers because access requires gearbox removal. If the gearbox is out, replace the bearing along with the clutch kit and inspect the release fork, pivot/ball, and guide tube for wear.

Common signs it’s had enough include a chirp or whirr that changes when the clutch pedal is lightly pressed, rough engagement feel, or noise that appears only with the pedal down. If any of that pops up, it’s worth a proper check to avoid collateral damage to the pressure plate fingers.

• During servicing, listen for pedal‑dependent noises and check free play and pedal feel.
• When refitting, lightly lubricate the release fork pivot and input shaft splines with the specified high‑temp moly grease, keep grease off the friction surfaces and bearing face.
• Confirm the bearing slides freely on the guide tube and that the clutch fork return spring is intact.
• If the vehicle has a CVT, there’s no clutch thrust bearing to service. Any driveline noise should be diagnosed within the CVT/torque converter system instead.

Quality parts and tidy installation make all the difference. A smooth, quiet clutch action means the thrust bearing is doing its job — and the XV is ready for plenty more kilometres of easy shifting.

Does my 2015 Subaru XV have a thrust bearing?

All versions have an engine crankshaft thrust bearing inside the main bearings. If it’s a 6‑speed manual, it also has a clutch thrust (release) bearing. CVT models don’t have a clutch thrust bearing.

What noises point to a failing thrust bearing on a manual XV?

A light whirr, chirp, or grinding that appears with the clutch pedal depressed and fades when released is classic thrust/release bearing noise. If the sound changes with slight pedal pressure, get it checked before it nicks the pressure plate fingers.

Should the thrust bearing be replaced on its own or with the clutch?

Because the gearbox has to come out, it’s smart to replace the thrust bearing with the full clutch kit. That keeps labour efficient and resets the whole system for long, trouble‑free service.
