Parts for your 2018 Toyota Rav4-Oil seals

2018 Toyota RAV4 oil-seals — what they do and when to replace them

Based on Toyota’s factory Repair Manual for the XA40 RAV4 (2013–2018), the Toyota Electronic Parts Catalogue, and Aisin transmission documentation for the U760E/U661E transaxles used in this model, oil-seals are absolutely fitted to the 2018 Toyota RAV4. You’ll find them at the front and rear of the crankshaft, at the transaxle input and output shafts, where the front driveshafts enter the transaxle, and on AWD models, at the transfer and rear differential pinion/side shafts. They’re essential to keep engine oil, ATF WS, and final drive gear oil where they belong.

Oil-seals are small but mighty. They keep lubricant in, keep dust and water out, and let rotating shafts spin freely. On the RAV4’s 2.5‑litre petrol engine, the front and rear crankshaft oil-seals prevent engine oil seepage at the crank pulley and the bellhousing area. In the transaxle, lip seals keep ATF from weeping around the torque converter/input and the driveshaft stubs. AWD models also rely on oil-seals in the transfer case and rear diff to hold 75W‑85 gear oil under tough Aussie and Kiwi conditions.

There’s no fixed replacement interval for oil-seals
