Parts for your 2017 Subaru Outback-Thrust bearing

2017 Subaru Outback thrust-bearing: what’s actually fitted and what to service

Based on Subaru technical references — the 2015–2019 Outback Workshop Manual (transmission sections for Lineartronic CVT TR580/TR690 and the 6‑speed manual), and Subaru’s electronic parts catalogue (FAST/EPC) — a “thrust bearing” in the clutch sense (also called a clutch release or throwout bearing) is only relevant to 2017 Outback models fitted with the 6‑speed manual gearbox. Petrol 2.5i and 3.6R models use the Lineartronic CVT, which has a torque converter and no clutch release/thrust bearing to service. All engines do have crankshaft thrust bearings inside the engine, but those are internal main bearing components addressed only during engine rebuilds, not routine servicing.

• CVT 2.5i and 3.6R: No clutch thrust/release bearing is used. The CVT’s torque converter and internal lock‑up clutch take care of engagement, so there’s nothing in the bellhousing that resembles a traditional thrust bearing.
• 2.0D 6‑speed manual (where fitted in AU/NZ): Uses a conventional clutch release (thrust) bearing inside the bellhousing acting on the pressure plate via the clutch fork.
• Engine thrust bearings: Present in all engines but not a service item, only inspected/replaced during engine overhaul per the Workshop Manual.

If their 2017 Subaru Outback is one of the manual 2.0D variants, it will have a clutch thrust bearing. Its whole job is to let the clutch disengage smoothly when the pedal’s pressed. The bearing rides on the gearbox input shaft guide tube and is moved by the fork (and slave cylinder on hydraulic setups) to push on the pressure plate’s diaphragm spring. Done right, it’s quiet and drama‑free, when it wears, there’s usually a chirp or whirr with the pedal down that vanishes when the pedal’s released.

There’s no scheduled replacement interval in Subaru’s service docs, the thrust bearing is typically renewed whenever the clutch is replaced. If the pedal‑down noise starts up, or the clutch feels notchy, it’s time to plan the job. Best practice in the workshop is to replace the clutch as a kit — disc, pressure plate and release (thrust) bearing together — and inspect related bits while the box is out. That means checking the clutch fork and pivot, the guide tube for scoring, the gearbox input shaft seal for weeps, and the rear main seal. On diesel models with a dual‑mass flywheel, measure freeplay and backlash against spec and address any excess before it cooks a fresh clutch.

A light smear of the correct high‑temp moly grease on the fork contact points and guide tube helps the new bearing live a long, quiet life. Don’t overdo it — excess grease can fling onto the friction surfaces. After refit, bleed the hydraulics (if equipped), confirm pedal freeplay is to spec, and road test. To extend life, avoid riding the clutch at lights and keep foot pressure off the pedal on the motorway. With sensible driving, a quality thrust bearing can comfortably go the distance between clutch jobs, often well past 150,000 kilometres in mixed use.

Does a 2017 Outback with CVT have a thrust bearing?

No. The CVT models (2.5i and 3.6R) use a torque converter, so there’s no clutch release/thrust bearing to service. Any “thrust bearing” mention for those cars refers only to internal engine components, not a routine service item.

How long should a clutch thrust bearing last on a manual 2017 Outback?

With normal driving, it often lasts as long as the clutch assembly — commonly well over 100,000–150,000 kilometres. It’s best replaced whenever the clutch is renewed, or sooner if it becomes noisy with the pedal depressed.

What are the signs of a failing thrust bearing on a manual Outback?

Typical clues are a chirp, rumble or whirr when the clutch pedal is pressed that disappears when the pedal’s released, a rough or notchy pedal feel, or vibration through the pedal. If it’s noisy, plan a clutch/transmission-out inspection.
