Parts for your 2011 Subaru Exiga-Thrust bearing

2011 Subaru Exiga thrust-bearing — what it does and when to sort it

Yes, a thrust-bearing is absolutely relevant on a 2011 Subaru Exiga. The boxer engines used in this model range (EJ20 and, in some markets, later FB-series) include an integrated crankshaft thrust-bearing surface within the main bearing set. This is documented in Subaru’s YA-chassis Exiga Factory Service Manual (STIS), engine overhaul section, and echoed by bearing catalogues from ACL and Clevite that list thrust bearings for EJ/FB applications. Those sources also outline crankshaft end-float checks as part of engine assembly, confirming the part’s presence and purpose.

The thrust-bearing’s job is to control axial (fore–aft) movement of the crankshaft. Every time the clutch is pressed on a manual, or when axial loads transfer through the torque converter on an auto/CVT, that force tries to push the crank along its axis. The thrust-bearing shoulders that load so the crank doesn’t “walk”, protecting the crank, main bearings, and transmission pump or clutch hardware. In day-to-day use, a healthy thrust-bearing keeps gear engagement sweet, idle stable with the clutch in, and oil clear of glittery bronze or steel particles.

It’s not a routine replacement item, but it deserves attention during servicing—especially on higher‑kilometre imports common in Australia and New Zealand. Good workshops will:

• Listen for a change in engine note when the clutch is depressed (manual) and check for pedal bite moving around.
• Check crank end-float if there’s any suspicion of axial knock, using a dial gauge at the crank pulley.
• Cut and inspect the oil filter for metallic debris if bearing concerns arise.
• Confirm correct idle speed and transmission line pressure settings on auto/CVT cars.

If replacement is needed, it’s an engine-out, bottom-end job. The main bearing set (with thrust faces) is renewed, crank thrust surfaces are measured and polished or the crank replaced if out of spec, and end-float is set to the factory window during reassembly. It’s smart to pair this with a new rear main seal, fresh sump sealant, and a clutch kit on manuals (release bearing included). For autos/CVTs, inspect the converter hub and front pump bushing. Stick with quality bearings—OEM Subaru or reputable brands like ACL—use the specified oil grade, and service on time (around 10,000–12,500 km or 12 months, depending on your local schedule) to keep thrust loads and wear under control. Treated well, the thrust-bearing should last the life of the engine without drama.

Popular questions about 2011 Subaru Exiga thrust-bearing

Does a 2011 Exiga actually have a thrust-bearing?
It does. Subaru’s factory service literature for the YA Exiga shows the crankshaft supported by main bearings that include thrust faces to control end-float. Aftermarket bearing catalogues for EJ/FB engines list matching thrust-bearing parts as well, so it’s a standard feature of the boxer engine, not an optional extra.

When should the thrust-bearing be replaced?
There’s no fixed interval—it’s generally only replaced during an engine rebuild or if there are symptoms like changing clutch bite point, idle stumble with the clutch in, axial knocking at the front of the engine, or metallic particles in the oil. A proper diagnosis includes measuring crank end-float against the factory spec.

What causes thrust-bearing wear on an Exiga?
High clutch pedal loads and habits like riding the clutch can add axial force on manuals. For autos/CVTs, incorrect line pressure, converter issues, or poor lubrication can contribute. Running the wrong oil grade, overdue services, and high heat all accelerate bearing wear.
