Parts for your 1999 Subaru Forester-Thrust bearing

1999 Subaru Forester thrust-bearing: what it is, if you have one, and how to look after it

Referencing the Subaru Factory Service Manual for the SF-series Forester (MY1999, Clutch section) and the Subaru OEM parts catalogue, the 1999 Subaru Forester fitted with a manual gearbox uses a pull‑type clutch release bearing, commonly called a thrust bearing. Automatic 4EAT models don’t use a serviceable clutch thrust bearing because there’s no manual clutch, any thrust bearings inside the auto are internal transmission components and not a routine service item. Engine crankshaft thrust bearings also exist in all EJ engines, but they are part of the main bearing set and not serviced as a standalone “thrust-bearing” in regular maintenance.

On a manual 1999 Forester, the thrust (release) bearing’s job is simple but vital: it transfers pedal force to the pressure plate to disengage the clutch, letting drivers shift gears smoothly. Subaru’s pull‑type design clips the bearing to the pressure plate and “pulls” it to release, which is why correct installation and clip engagement matter so much.

Owners will often first notice a croaky squeal, rumble, or whirr when the clutch pedal is pressed, especially cold. Other giveaways include a notchy pedal, vibration through the pedal, clutch drag when selecting reverse, or gears that baulk. Left unchecked, a tired bearing can score the input shaft sleeve/guide tube and accelerate wear of the pressure plate fingers.

There’s no fixed kilometre interval to replace a thrust bearing, it’s usually renewed whenever the clutch is out. Best practice during a clutch service is to fit a quality clutch kit that includes a new release (thrust) bearing, pressure plate, friction disc, and pilot bearing/bush. Exedy, Aisin and Subaru OEM literature all recommend replacing the release bearing as a set item rather than reusing the old one.

• Always verify the pull‑type clip is correctly seated on reassembly, an incorrectly latched clip can pop free and cause loss of clutch action.
• Lightly lube the bearing guide tube and fork pivot with a high‑temp moly grease—never over‑grease, and keep grease off the friction disc.
• Inspect the clutch fork, pivot ball, guide tube, and input shaft splines for wear, replace any scored parts to avoid repeat issues.
• Torque the bellhousing fasteners to spec and bleed/adjust the clutch hydraulics (if applicable) for proper pedal feel and release point.

For drivers with the 4EAT automatic, there’s no clutch thrust bearing to service. If there are drivetrain noises, diagnosis focuses on torque converter, flexplate, or internal transmission components rather than a release bearing.

Popular questions about 1999 Subaru Forester thrust-bearing

Does a 1999 Subaru Forester have a thrust bearing?

Manual models do—Subaru uses a pull‑type clutch release (thrust) bearing on the SF‑series Forester. Automatic 4EAT versions don’t have a serviceable clutch thrust bearing because they don’t use a manual clutch. The engine’s crankshaft thrust bearing exists in all variants but isn’t a routine service item.

What are the symptoms of a failing thrust bearing on a 1999 Forester?

Common signs include a squeal or rumble when the clutch pedal is depressed, a gritty or notchy pedal feel, difficulty engaging gears (especially reverse), and clutch drag at a standstill. If noises stop when the pedal is released, the release/thrust bearing is a prime suspect.

Should the thrust bearing be replaced with the clutch?

Yes. Whenever the gearbox is out, it’s smart to replace the clutch assembly and the release (thrust) bearing together. This avoids paying labour twice and ensures the new friction parts aren’t let down by a worn bearing or clip. Many workshops also check the rear main seal, pilot bearing, and guide tube at the same time.
