Subaru Impreza Engine Mount: Specs, Fitment & Common Faults

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

Genuinely important to know: most Imprezas use three separate mounts (engine, transmission, and a rear torque strut) rather than one part covering the whole job — check which one is actually worn (a common DIY mistake is replacing all three when only one has failed) before ordering.

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 Impreza 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 Impreza 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.
