Parts for your 2009 Toyota Aurion-Oil seals

2009 Toyota Aurion oil seals — what they do and when to replace

Oil seals are absolutely fitted to the 2009 Toyota Aurion (GSV40R, 2GR‑FE 3.5L V6 with U660E 6‑speed auto). Toyota’s factory repair manuals for the Aurion/Camry V6 and the Aisin U660E transaxle overhaul manual specify multiple seals: front crankshaft oil seal, rear main seal, and left/right transaxle (differential side) output shaft oil seals, among others. Toyota’s Electronic Parts Catalogue also lists these seals as serviceable components. So yes—oil seals are relevant on a 2009 Toyota Aurion.

On this Aurion, oil seals keep engine oil and transmission fluid where they belong, stopping drips, mess, and fluid loss. When they harden with age or get nicked during previous work, they can weep or leak, leading to spots on the driveway, a hot‑oil whiff under the bonnet, or ATF slung around the inner wheels.

• Common 2009 Toyota Aurion oil seals: front crankshaft seal, rear main seal, and U660E transaxle LH/RH output (drive shaft) oil seals.

They’re not a scheduled “consumable” like filters, they’re replaced when signs of leakage appear. As part of normal servicing, a technician should inspect the front of the engine around the crank pulley, the bellhousing area (rear main), and the transaxle where the driveshafts enter. Any fresh oil or ATF tracking, dampness, or dust‑stuck residue is a clue to act sooner rather than later.

Replacement tips for the 2009toyotaaurion oilseals: go with quality (genuine or reputable aftermarket), use the correct seal driver and depth, lightly lube sealing lips, and clean the bore. The rear main seal is labour‑heavy because the transmission needs to come out. The front crank seal requires balancer removal. The U660E axle seals need fluid drained and then refilled with Toyota WS ATF to the correct level and temperature procedure. If crankcase pressure is high (blocked PCV), new seals may weep again—so check PCV operation. Sticking to the recommended oil grade and avoiding overfilling helps seals live longer.

Typical lifespan? Many go 150,000–250,000 km or more, but age, heat, and driving conditions matter. If there’s a small weep, monitor levels and plan the job, if it’s dripping or hitting the exhaust or clutch surfaces, book it in promptly to avoid bigger repairs.

Popular questions about 2009 Toyota Aurion oil seals

Do all 2009 Aurions actually have engine and trans oil seals?

Yes. The 2GR‑FE V6 uses a front and rear crankshaft oil seal, and the Aisin U660E auto has left and right output (drive shaft) oil seals. These are documented in Toyota’s Aurion/Camry V6 repair literature and the Aisin transaxle overhaul manual, and appear in Toyota’s parts catalogue.

When should the rear main seal be replaced on a 2009 Aurion?

There’s no fixed interval—it’s done when leaking. A tell‑tale is oil appearing at the bellhousing. Because the transmission must be removed, many owners time the job with a major clutch service on manuals (rare in Aurion) or when the auto is already out for other work, to save labour.

Is it safe to drive with a small axle (output) seal leak on the U660E?

Short term, maybe—but only if ATF level is checked frequently and topped up to spec. Left alone, a leaking seal can drop fluid, cause shift issues or trans damage, and fling ATF onto brakes or suspension. It’s best to schedule the seal and fluid service soon.
