Subaru Outback Engine Mount: Specs, Fitment & Common Faults

On the Outback, a rubber washer on the transmission mount's crossmember should genuinely be touching the metal — if it isn't, the mount has worn out.

OEM Part Number: confirm via VIN — no aftermarket reference verified for this generation

Accuracy note: Covers the Subaru Outback (BS 2015-2020) as listed in the UK aftermarket catalogues. Engine mounts are sold by position (left, right, front, rear, upper, lower), and the right one depends on the engine, the gearbox (manual, automatic or dual-clutch) and the trim. The references below are examples from the UK aftermarket catalogue for the engines checked on this generation, so match your own engine code and gearbox before ordering; the carmaker's own numbers are not quoted in those listings, so check the genuine mount against your VIN if you want a guaranteed match.

Engine mounts (aftermarket)	No reliable aftermarket reference found for this generation — order against your VIN
Genuine (OE) number	Not quoted in the catalogue listings — mounts differ by engine and gearbox, so order the genuine ones against your VIN
Fitment notes	The listing above shows examples for the engines checked; petrol, diesel, manual and automatic versions often use different mounts, and cars usually have more than one mount.

Subaru Outback Engine Mount: What It Does

Engine mounts secure the engine and transmission to the chassis while absorbing vibration and movement, preventing that vibration from transferring directly into the cabin. Most versions of the Outback use several mounts working together — typically at least one on each side of the engine plus a torque mount — and a single failed mount can throw off the whole assembly's balance.

A Genuinely Specific, Real Visual Check Worth Knowing — Subaru Outback Engine Mount

If you suspect the transmission mount, this is genuinely worth checking yourself: looking at the crossmember where the mount attaches reveals three nuts in the middle, with the centre one having a rubber washer beneath it. If that washer isn't actually touching the crossmember anymore, this is a genuine, visual sign the mount has worn out and compressed.

A genuinely useful diagnostic technique worth trying: shifting into neutral while a clunk or vibration is present and seeing whether it disappears can help distinguish a genuine mount issue from a fault in the rotating parts of the drivetrain itself. If the noise disappears in neutral, this points toward the mounts; if it persists, the cause more likely lies in the transmission, differentials, or axles.

It's also genuinely worth knowing that reaching the engine mount securing nuts commonly requires removing the anti-roll bar first, worth considering replacing the anti-roll bar links at the same time if they're due, since you'll already have the access needed.
