Parts for your 2021 Toyota Rav4-Oil seals

2021 Toyota RAV4 oil seals — what they do and when to replace them

Based on Toyota’s 2021 RAV4 repair manual set (AXAA5#/AXAH5#), the Toyota Electronic Parts Catalogue, and Aisin drivetrain service information, oil seals are absolutely used on the 2021 Toyota RAV4. They’re fitted to the crankshaft (front and rear), camshafts, the transaxle/eCVT output shafts, transfer case and differentials (on AWD). So oil-seals are relevant to every 2021 RAV4 variant, petrol and hybrid alike.

Oil seals do the quiet, messy work—keeping engine oil and transmission fluid where they belong while letting rotating shafts spin freely. On a 2021 RAV4 that means the front crank seal behind the crank pulley, the rear main seal between engine and gearbox, cam seals at the timing end, and driveshaft oil seals where CV shafts exit the transaxle or rear diff. Hybrids still have engine oil seals, and their eCVT and drive units use seals to hold ATF and gear oil in.

They’re not a scheduled “every X kilometres” replacement item
