Parts for your 2020 Subaru Legacy-Thrust bearing

2020 Subaru Legacy thrust-bearing — is it fitted, and does it need servicing?

Based on Subaru’s 2020 model-year technical literature and specifications, the 2020 Subaru Legacy is delivered exclusively with a Lineartronic CVT (continuously variable transmission), paired to the 2.5‑litre FB25 or 2.4‑litre turbo FA24 engine. There’s no manual gearbox option for this model year, which means there’s no clutch assembly — and therefore no clutch thrust/throw-out bearing fitted.

This conclusion aligns with Subaru’s New Car Information for 2020MY Legacy/Outback, the Subaru service manual set (CVT and engine sections within STIS), and the 2020 Legacy owner’s manual and press specifications that list the CVT as standard across the range. A clutch thrust bearing is only relevant on a manual transmission with a friction clutch.

So, why isn’t a thrust-bearing used here? The Legacy’s CVT uses a torque converter and a belt-and-pulley system to manage drive, so there’s no clutch release mechanism that would require a throw-out (thrust) bearing. The drivetrain is designed to operate without that component, delivering smooth take-up via the converter and hydraulic control.

It’s worth noting there are other “thrust” bearings in the vehicle, but they aren’t customer-service items:

• Clutch thrust/throw-out bearing: Not fitted on the 2020 Legacy (no manual clutch).
• Engine crankshaft thrust bearing: Integrated in the main bearings to control crank end-float, only addressed during engine overhaul.
• Internal CVT thrust/needle bearings: Located inside the transmission, not serviced separately outside a transmission rebuild.

Owners searching for a “thrust-bearing noise” on a 2020 Legacy are usually chasing something else — for example, torque converter shudder, CVT whine, an accessory/idler pulley, or even a wheel bearing. The best play is to keep up with scheduled servicing, use the correct Subaru CVTF where applicable, and have any driveline noise checked by a technician familiar with Subaru CVTs. If a supplier lists a clutch thrust/throw-out bearing for a 2020 Legacy, it’s not applicable to this model year’s factory spec.

Popular questions

Does a 2020 Subaru Legacy have a clutch thrust (throw-out) bearing?
No. The 2020 Legacy is CVT-only, so there’s no manual clutch and no throw-out bearing. Drive take-up is handled by a torque converter, not a friction clutch.

Is there any thrust bearing in the 2020 Legacy’s engine, and does it need servicing?
Yes — the crankshaft uses a thrust bearing as part of the main bearing set to control end-float. It isn’t a routine service item and is only inspected or replaced during engine rebuild work.

Hearing a noise like a bad thrust bearing — what should a 2020 Legacy owner check?
On this model, similar noises are more likely from the torque converter, CVT, accessory/idler pulleys, or a wheel bearing. Have a technician road test and scan it, verify CVTF condition, and rule out ancillary bearings before considering transmission-internal faults.
