Parts for your 2020 Mitsubishi Eclipse cross-Oil seals

2020 Mitsubishi Eclipse Cross oil seals

Oil seals are absolutely used on the 2020 Mitsubishi Eclipse Cross. Technical sources including the Mitsubishi Motors Workshop Manual for the 4B40 1.5‑litre turbo engine and W1C/Jatco CVT, plus the Mitsubishi ASA electronic parts catalogue, list multiple oil seals: front and rear crankshaft seals, CVT input/output and driveshaft seals, transfer case and rear differential seals on AWD models. These seals are engineered to keep lubricants in and grit out, so the engine, transmission and driveline can do their job without leaks or contamination.

On this model, oil seals sit at key rotating shafts where fluids live under pressure or splash—think the crank pulley end, behind the flywheel/flexplate, around the CVT’s output stubs and at the AWD rear diff. When they harden or wear, tell‑tales include fresh weep marks, oil mist around the timing cover, drips at the bellhousing, CVT fluid seep at the driveshafts, or a burnt‑oil whiff after a drive. Left alone, a small seep can become a mess, lower fluid levels and shorten the life of expensive components.

• Ask for a seal check at every service (typically 12 months/15,000 km in AU/NZ), especially around the crank pulley, bellhousing, and CVT/axle areas.
• If a seal is weeping, plan replacement sooner rather than later. Combine the job with related work (e.g., when a driveshaft is out or the CVT is being serviced) to save on labour.
• Use genuine or OE‑quality seals and the correct sealant where the workshop manual specifies. Seal depth and alignment matter—special install tools help avoid lip damage.
• Lightly oil the seal lip on installation and clean the shaft surface
