Parts for your 2014 Subaru Legacy-Engine mount

2014 Subaru Legacy engine mount — purpose, care, and when to replace

Technical references, including the Subaru Factory Service Manual (FSM) for the 2014 Legacy/Outback (BM/BR) and the Subaru FAST parts catalogue (Engine Mounting group), confirm that the 2014 Subaru Legacy (known as Liberty in Australia) is fitted with engine mounts. The platform uses a pair of hydro-elastic engine mounts on the subframe and a separate transmission mount to control powertrain movement on both FB25 2.5‑litre and EZ36 3.6‑litre models.

On this Legacy, the engine mounts act like firm-but-flexible buffers between the engine and the front crossmember. Their job is to hold the engine in place under the bonnet, soak up vibration, and stop the donk from lurching during take-off, braking, and quick gear changes. They keep the cabin calm and help protect exhaust joints, hoses, and wiring from stress when the engine twists under load.

While engine mounts aren’t a scheduled replacement item, they do age. Heat, oil exposure, and kilometres can harden the rubber or cause the fluid inside the hydraulic mounts to leak. Once that happens, the car can feel rougher at idle, thump on acceleration, or shudder when shifting.

Typical signs the mounts on a 2014 Legacy may need attention include:

• Noticeable vibration in Drive at the lights that eases in Neutral
• Clunks or a “rocking” feel on start-up, lift-off, or gear changes
• Visible sagging, cracked rubber, or fluid stains on the mount bodies

As part of regular servicing, it’s smart to inspect the mounts every 20,000–30,000 km or annually. A technician will check for fluid seepage, perishing, uneven engine height, and excessive movement when the throttle is blipped in gear with the brakes applied.

If replacement’s needed, doing both engine mounts together keeps balance and NVH consistent. Quality is key here—choose genuine or reputable equivalents matched to the FB25 or EZ36. Replacement involves safely supporting the engine, loosening the mount-to-bracket hardware, and lifting slightly to swap each mount. Fresh hardware and correct torque matter to avoid vibration or fastener stretch.

Left too long, failed mounts can stress exhaust flex joints, CVT/gearbox mounts, and even driveline bushes, so timely attention can save bigger bills. Sorted mounts bring back that smooth, quiet feel the Legacy is known for on Aussie and Kiwi roads.

Popular questions about 2014 Subaru Legacy engine mounts

How long do the engine mounts typically last?
Many owners see 120,000–200,000 km before noticeable wear, depending on conditions and driving style. City stop–start, heat, and oil leaks can shorten lifespan. Regular inspections will catch early signs before they turn into harsh vibration or clunks.

Can worn engine mounts damage other components?
Yes. Excess engine movement can stress the exhaust, CVT/gearbox mount, and ancillary hoses or wiring. It may also worsen cabin NVH and make the car feel unsettled on take-off. Replacing tired mounts helps protect those parts.

Should both engine mounts be replaced at the same time?
Best practice is to replace them as a pair. It keeps engine height and stiffness even from side to side, reducing the chance of lingering vibration and ensuring consistent feel under load.
