Parts for your 2014 Subaru Legacy-Strut mounts

2014 Subaru Legacy strut mounts — what they do and when to replace

Based on technical references including the Subaru Legacy/Outback BM/BR Factory Service Manual (Front Suspension), the Subaru Genuine Parts Catalogue for MY2014 Legacy, and aftermarket fitment catalogues from KYB and Monroe, the 2014 Subaru Legacy is fitted with MacPherson struts at the front that use a dedicated strut top mount with an integrated bearing. The rear uses a multi-link/wishbone layout with a separate shock and coil spring, so there isn’t a rear “strut mount” in the strict sense—just a rear shock upper mount. So yes, strut mounts are absolutely relevant on the front of a 2014 Subaru Legacy.

On this model, the front strut mount does two jobs. First, it isolates bumps and road harshness from the body using a thick rubber insulator, cutting down on NVH in the cabin. Second, the mount’s bearing lets the strut and spring rotate smoothly when steering, which helps the wheel self‑centre and keeps steering feel consistent. When the rubber hardens or cracks, or the bearing wears, you’ll often get clunks over sharp bumps, a creak or notchy feel at low‑speed turns, and vague or chattery feedback through the wheel.

As part of regular servicing in Aussie and Kiwi conditions, it’s smart to inspect the front strut mounts from about 60,000–80,000 kilometres onward, and any time the front struts are being replaced. A quick check under the bonnet for perished rubber, plate distortion, or rusty cups, followed by a road test for noise on lock and over speed humps, goes a long way. If one side has failed, best practice is to replace mounts in pairs for even ride height, consistent steering effort, and balanced NVH.

Got a Legacy that’s done big country kilometres or lives on corrugated roads? Consider new mounts whenever fitting fresh struts and coil springs. Reusing a tired mount can undo the benefits of new dampers. After replacement, a proper wheel alignment is recommended—MacPherson geometry relies on the top mount position, and small changes can shift camber or caster. Use new self‑locking nuts where specified, and don’t preload the mount, the bearing should turn freely with the weight of the car on its wheels.

Quality OE‑equivalent mounts will restore steering smoothness and trim down cabin buzz. It’s a tidy, worthwhile upgrade that helps the Legacy feel tight and planted again without adding harshness to the ride.

• Symptoms of worn strut mounts:
  • Clunking or thudding over bumps
  • Creaking/notchy steering at parking speeds
  • Visible cracking or separation of the rubber
  • Uneven tyre wear when combined with strut wear or alignment drift

Does the 2014 Subaru Legacy have strut mounts front and rear?

The front definitely does—MacPherson struts use a top mount with a bearing. The rear on this generation uses a multi‑link setup with a separate shock and spring, so there’s a shock upper mount rather than a traditional strut mount.

How long do front strut mounts last on a 2014 Legacy?

It varies with roads and load, but many last well past 100,000 km. Check them from 60,000–80,000 km and any time you’re replacing struts. Noise over bumps or notchy steering on lock are common signs they’re due.

Do you need a wheel alignment after replacing the strut mounts?

Yes. The MacPherson layout means even small changes at the top mount can alter alignment. Get a full alignment after any strut or mount work to keep tyre wear in check and steering feel bang‑on.
