Parts for your 2024 Mitsubishi Eclipse cross-Oil seals

2024 Mitsubishi Eclipse Cross oil seals: what they do and when to sort them

Oil seals are absolutely used on the 2024 Mitsubishi Eclipse Cross. Mitsubishi Motors service information and the ASA parts catalogue for the Eclipse Cross (MY2024) list multiple radial lip oil seals across the powertrain, and CVT service literature specifies input/output shaft and driveshaft seals for the transaxle, with additional transfer unit seals on AWD models. So yes—oil seals are very much relevant to this vehicle.

On this Eclipse Cross, oil seals keep fluids where they should be and dirt where it shouldn’t. Around the engine you’ll find a front crankshaft seal (behind the crank pulley) and a rear main seal (between engine and transaxle), plus camshaft seals at the timing end. The CVT runs several seals too: input and output shaft seals, and driveshaft/axle seals. AWD versions add transfer unit and prop-shaft seals. Their job is simple: hold pressurised oil or CVT fluid inside rotating housings while the shafts spin—no leaks, no dust ingress, no dramas.

• Common leak spots: front of engine (crank pulley area), bellhousing join (rear main), CVT case around driveshafts, and AWD transfer unit flanges.
• What you’ll notice: oil sweat or drips on the undertray, spots on the driveway, a whiff of burning oil, or low engine/CVT fluid levels. Engine oil is typically amber/brown, CVT fluid is often greenish.

Oil seals aren’t a scheduled replacement item, but they should be inspected at each service. A trusted mechanic will check for weeping and dust accumulation around seal lips and verify breather/PCV systems aren’t over-pressurising the crankcase or transaxle—excess pressure can push past a good seal. If a seal is damp but not dripping, monitor, if it’s actively leaking, replace it sooner rather than later to avoid clutch, belt, or bearing damage.

Replacement is straightforward for some seals and a bit of a mission for others. Front crank and driveshaft seals are typical workshop jobs, the rear main seal is more involved because the transaxle has to come out. Best practice includes cleaning the bore, lightly lubricating the new seal lip, pressing it square to the specified depth, checking shaft surfaces for grooves, and renewing companion O-rings or gaskets. Always refill with the correct grade fluids and run a post-repair leak check.

Good news is the seals themselves are inexpensive—the real cost is labour. Catching leaks early at regular services saves both fluid and future headaches.

Popular questions about 2024 Mitsubishi Eclipse Cross oil seals

Where are the oil seals on a 2024 Eclipse Cross?
The engine has front and rear crankshaft seals and camshaft seals at the timing end. The CVT has input/output shaft seals and driveshaft/axle seals. AWD models also have transfer unit and prop-shaft seals. These sit where rotating shafts exit housings to keep fluids in and contaminants out.

Are oil seals a regular service item?
No. They’re inspected at service time but only replaced if leaking or damaged. Mechanics look for weeping, dust build-up, and drops in engine or CVT fluid levels, and they check breathers/PCV to prevent pressure-related leaks.

Can a leaking oil seal cause damage if ignored?
Yes. Engine oil leaks can contaminate belts or the clutch area and starve components of lubrication. CVT fluid leaks risk belt/pulley wear and overheating. Sorting leaks promptly prevents bigger bills down the track.
