Parts for your 2017 Mitsubishi Eclipse cross-Engine mount

2017 Mitsubishi Eclipse Cross engine mount — what it does and when to replace it

Engine mounts are absolutely used on the 2017 Mitsubishi Eclipse Cross. Technical references that confirm this include the Mitsubishi Motors Eclipse Cross Workshop Manual (GK1W/GK9W, 2017–, Engine: Engine Mounting section) and the Mitsubishi ASA electronic parts catalogue for GK-series models, which list multiple mounts: a right-hand engine mounting insulator, a left-hand transaxle mount and a front roll stopper (often called a torque rod or dog-bone).

On a 2017 Eclipse Cross, the engine mounts keep the 1.5‑litre turbo engine securely located under the bonnet while isolating vibration so the cabin stays calm. They also control how much the engine can rock when taking off, shifting gears or backing off the throttle. Most mounts on this model are rubber or hydraulic, the hydraulic type is fluid-filled to better soak up idle vibes and stop that harsh buzz through the steering wheel. When mounts wear, crack or leak, drivers will often notice a shakier idle, a thump on take‑off, or extra movement when blipping the throttle.

There’s no fixed replacement interval for engine mounts on the Eclipse Cross, they’re inspected during regular services and replaced on condition. In Aussie and Kiwi conditions—stop‑start traffic, corrugations, heat—checking them every service makes sense. Look for split rubber, collapsed mount height, shiny witness marks from movement, or fluid seepage from the hydraulic mount. If any of that shows up, it’s time to sort it.

Replacement is straightforward for a trained tech: safely support the engine with a bar or jack and block, remove the affected mount and brackets, then refit and torque everything to the workshop manual specs. Final torque should be done at normal ride height so the mount isn’t preloaded. Genuine or high‑quality aftermarket mounts are worth the spend, as cheapies can transmit more NVH. After fitting, expect a smoother idle and cleaner shifts.

If the Eclipse Cross starts knocking under load, shuddering at idle, or you can see the engine lurch when shifting from Reverse to Drive, don’t put it off. A failed mount can stress exhaust flex joints, hoses and driveshafts. Budget roughly 1–2 hours labour per mount depending on which side and AWD packaging, and always follow the service manual procedures for the GK‑series.

• Common symptoms: vibration at idle, clunk on take‑off, excessive engine movement, visible cracks or hydraulic fluid leak
• Service tip: inspect every service, replace on condition, torque to spec at ride height

FAQs

How long do engine mounts last on a 2017 Eclipse Cross?
In typical Australian and New Zealand use, many last well past 100,000 km, but life varies with driving style and conditions. Regular inspections during scheduled services will catch perishing rubber or hydraulic leaks before they get annoying.

Is it safe to drive with a bad engine mount?
Short trips may be possible, but it’s not ideal. A failed mount can cause harsh vibration, clunks and extra movement that can stress exhausts, hoses and CV joints. It’s best to book replacement promptly to avoid knock‑on damage.

How many engine mounts does the 2017 Eclipse Cross have?
The GK‑series Eclipse Cross uses multiple mounts: typically a right‑hand engine mounting insulator, a left‑hand transaxle mount and a front roll stopper/torque rod. Exact count and layout can vary slightly by drivetrain.
