Parts for your 2001 Subaru Forester-Thrust bearing

2001 Subaru Forester thrust-bearing: what it is, where it lives, and when to sort it

Based on Subaru’s Factory Service Manual for the 2001 Forester (SF, Clutch System section) and the Subaru engine manual (Crankshaft/Main Bearing section), a thrust-bearing is indeed used on this model. Manual-transmission Foresters have a clutch release bearing (commonly called a thrust bearing), and the EJ25 engine uses thrust surfaces as part of its crankshaft main bearing set. Automatic 4EAT models don’t have a clutch release thrust bearing (the torque converter takes its place), which is consistent with Subaru’s Automatic Transmission (4EAT) service documentation.

On a 2001 Forester with a manual gearbox, the clutch release bearing sits on the gearbox input shaft and presses against the pressure plate’s diaphragm spring to disengage the clutch. It lets the clutch mechanism spin while the clutch fork and hydraulic bits stay still, keeping shifting smooth and pedal effort easy. Many 2001 Forester manuals use a pull-type clutch, in these, the release bearing clips to the pressure plate and is disconnected via the service procedure outlined in the FSM—handy to know before grabbing the spanners.

There’s no scheduled replacement interval for the release/thrust bearing, it’s a replace-on-condition or “while you’re in there” item. Smart servicing bundles it with a complete clutch kit—pressure plate, disc, release bearing, and pilot bearing/bush—because labour to access the clutch is the big ticket. Typical warning signs include a chirp, squeal, or rough, growly feel when the clutch pedal is depressed, a notchier pedal, or clutch engagement that’s not as clean as it used to be. If noises change with pedal position, the release bearing is a prime suspect.

• Best practice during clutch work:
  • Replace the release bearing rather than trying to service it—modern units are sealed.
  • Add a light smear of high-temp grease on the clutch fork pivot, fork-to-bearing contact points, and the guide tube—never on the friction surfaces.
  • Inspect the fork, pivot ball, guide tube, and retaining clips, replace worn bits to avoid repeat jobs.
• For autos (4EAT): there’s no clutch release thrust bearing. If there’s a noise at idle, look elsewhere (idler pulleys, A/C clutch, or transmission input bearings). The engine’s crankshaft thrust bearing isn’t a routine service item and is only addressed during engine rebuilds or if excessive end float is diagnosed per the engine FSM.

Whether it’s clocking up country kilometres or city runs, keeping the Forester’s clutch hardware in good nick pays off with cleaner shifts, a lighter pedal, and fewer surprises down the track.

Popular questions

Does a 2001 Subaru Forester have a thrust bearing?
Yes. Manual models use a clutch release (thrust) bearing, as detailed in Subaru’s 2001 Forester clutch system manual. The EJ25 engine also uses thrust surfaces in the main bearings. Automatic 4EAT models do not have a clutch release thrust bearing because the torque converter replaces the manual clutch setup.

What are the symptoms of a failing thrust/release bearing on a 2001 Forester?
Common signs are a chirp or squeal that appears when the clutch pedal is pressed, a rough or rumbly feel through the pedal, and less-smooth shifts. If the noise changes with pedal position, the release bearing is a likely candidate. If the noise is present all the time, look at belts, idlers, or gearbox bearings instead.

Should the thrust bearing be greased or just replaced?
The release bearing is a sealed unit—don’t wash or pack it with grease. Replace it whenever the clutch is out, and lightly grease only the fork pivot, contact points, and guide tube as specified in the Subaru service manual. That approach keeps things quiet and extends the life of the new parts.
