Parts for your 2013 Subaru Legacy-Strut mounts

2013 Subaru Legacy strut mounts — what they do and when to replace them

Technical references confirm strut mounts are absolutely relevant on the 2013 Subaru Legacy. The Subaru Factory Service Manual for the 2010–2014 Legacy/Outback (Front Suspension > Front Strut) specifies a MacPherson strut front end with an upper strut mount and bearing. Subaru’s global parts catalogue also lists a “Front Strut Mounting” assembly for this model. The rear of this Legacy uses a double-wishbone suspension with separate shock and spring, so there are no rear strut mounts.

Up front, the strut mounts connect the top of the strut to the body and carry the vehicle’s weight through the spring seat, while also isolating vibration and road harshness from the cabin. Inside the mount is a bearing that lets the strut rotate smoothly as the steering turns. When these mounts are in good nick, steering feels light and precise, noise is kept in check, and the tyres track true. As they age, the rubber can harden or crack, and the bearing can dry out. That’s when the Legacy can start clunking over bumps, creaking when turning, or show “memory steer” and vague on‑centre feel.

Because the mount supports the spring and manages steering rotation, it’s smart practice to replace the front strut mounts whenever front struts or springs are replaced. Labour overlaps heavily, and fresh mounts help protect new dampers. On Aussie and Kiwi roads, many owners see reliable service life in the 100,000–160,000 km range, but heavy loads, rough surfaces, or coastal exposure can bring replacement forward.

• Common signs it’s time: front-end clunks on bumps, notchy steering, a groan when turning at low speed, uneven front tyre wear, or a visible split in the rubber.
• Service tips: always use quality mounts with an integrated bearing, renew any single‑use fasteners, and have a wheel alignment done afterwards.
• Safety note: compressing coil springs demands proper tools, it’s best left to a qualified tech.

During routine servicing, a quick check under the guards for cracked rubber, perished insulators, or play at the strut top can catch issues early. If one side’s worn, doing both fronts together keeps steering feel consistent. Pairing mounts with new strut boots and bump stops is a tidy way to reset the front end and keep the Legacy riding quietly for the long haul.

Popular questions about 2013 Subaru Legacy strut mounts

Does a 2013 Subaru Legacy have strut mounts front and rear?
Yes for the front, no for the rear. The front suspension is MacPherson strut with a top mount and bearing. The rear is a double‑wishbone setup that uses separate shocks and springs, so there’s no rear strut mount to replace.

How long do front strut mounts last on a 2013 Legacy?
Many last 100,000–160,000 km, but lifespan depends on road conditions, loads, and climate. If there are clunks, steering notchiness, or tyre wear that won’t align out, it’s time to inspect and likely replace the mounts, ideally when fitting new front struts.

Do I need an alignment after replacing strut mounts?
Yes. Any time the front struts or mounts are disturbed, the alignment can shift. A proper wheel alignment restores steering feel, ensures even tyre wear, and makes the most of the new components.
