Parts for your 2011 Subaru Forester-Thrust bearing

2011 Subaru Forester thrust-bearing

Based on Subaru technical literature, a thrust-bearing is relevant to the 2011 Subaru Forester when it’s fitted with a manual gearbox. In Subaru documentation for the SH-series Forester, the clutch system specifies a clutch release (thrust) bearing operating on the transmission input shaft via the release fork and pressure plate diaphragm. This is confirmed in the Subaru Forester (SH) Service Manual, Clutch section, and by listings in the Subaru electronic parts catalogue for 5MT models. Automatic versions don’t use a clutch thrust-bearing at all, though the engine itself does have crankshaft thrust bearings integrated into the main bearings, these aren’t routine service items.

For manual Foresters, the thrust-bearing’s job is simple but critical: it transfers the force from the clutch fork to the pressure plate fingers, letting the clutch disengage smoothly when the pedal’s pressed. It has to spin freely under load and stay quiet. When it wears or runs dry, it can chirp, rattle or growl, and clutch feel often turns notchy or inconsistent. Left too long, a failing bearing can mark up the pressure plate fingers and shorten clutch life.

Best practice is to replace the thrust-bearing whenever the clutch is out—typically during a clutch kit service. Subaru service procedures specify inspecting the guide tube, release fork, pivot and clips, and applying a light coating of high-temp grease only to the bearing hub/guide and fork contact points. Don’t grease the bearing face that meets the pressure plate. It’s also worth checking clutch pedal free play, the slave cylinder operation, and the gearbox input shaft seal while you’re there. In Aussie and Kiwi conditions—stop–start traffic, towing, beach runs—bearing life varies, but many owners see 100,000–200,000 km if the clutch isn’t abused. If there’s any noise with the pedal depressed that disappears when released, or vice versa, book it in for a check. Quality OEM-spec parts and careful alignment during refit go a long way to quiet, long-lasting operation.

• Common signs: squeak or growl with the pedal pressed, shudder on take-off, rough pedal feel.
• Service tips: renew the release fork clips and pivot if worn, inspect the guide tube, verify smooth slave cylinder action, torque fasteners to Subaru specs.

Popular questions

Does a 2011 Subaru Forester automatic have a thrust-bearing?
Not a clutch thrust-bearing. Autos use a torque converter, so there’s no release/thrust bearing in the clutch sense. The engine does have crankshaft thrust bearings inside the block, but these aren’t part of routine servicing unless the engine is being rebuilt.

What noises point to a failing thrust-bearing on a 2011 Forester manual?
Typically a chirp, squeal or growl that appears with the clutch pedal depressed and quietens when you release it. If the noise is present with the pedal up and gets worse in neutral, it may be the gearbox input shaft bearing instead, so a proper diagnosis helps avoid guesswork.

Should the thrust-bearing be greased during installation?
Only at the correct contact points. A light smear of high-temp moly grease on the bearing hub where it slides on the guide and on the fork contact pads is recommended. Don’t grease the bearing face that meets the pressure plate, and don’t over-grease—excess can fling onto the friction surfaces.
