Parts for your 2017 Subaru Legacy-Suspension bushes

2017 Subaru Legacy suspension bushes

Yes, the 2017 Subaru Legacy is fitted with multiple suspension bushes. Technical references that detail these include the Subaru Factory Service Manual for the 2015–2019 Legacy/Outback (chassis: front and rear suspension sections) and Subaru’s genuine parts catalogue for the 2017 Legacy, which list front lower control arm bushes, stabiliser bar (sway bar) D-bushes, rear lateral link and trailing arm bushes, and rear subframe mounting bushes. The BN/BS Legacy uses a MacPherson strut front end and a multi-link/double-wishbone style rear, both of which rely on rubber bushes to control movement and isolate noise and vibration.

On this model, suspension bushes act like small, tough cushions between metal components. They let the arms pivot smoothly, keep alignment true under braking and cornering, and soak up the harshness from rough Kiwi and Aussie roads. When they’re healthy, steering feels centred, the car tracks straight, and tyre wear is nice and even. As they age, rubber hardens, cracks, or separates from its sleeve, hydraulic-style bushes can leak. That’s when the Legacy may start to wander, thud over bumps, or show feathered tyres.

For routine servicing of a 2017 Subaru Legacy’s suspension bushes, a visual and lever check every 20,000 km or annually is a smart move. Look for splits, perishing, or fluid seepage, and pay attention to clunks over speed humps, shudder under braking, or steering that won’t settle. If any front lower control arm rear bushes, stabiliser D-bushes, or rear link bushes are worn, replacement in axle pairs keeps handling balanced.

When fitting new bushes, torque all pivot bolts at normal ride height so the rubber isn’t pre-loaded — that helps them last. A wheel alignment after bush replacement is essential to protect tyres and restore crisp steering. OE-style rubber keeps noise and vibration low for daily driving, polyurethane options can sharpen response but may add a touch more NVH. If choosing poly for stabiliser bar D-bushes or certain arms, use the correct silicone-based grease and re-lube as recommended to prevent squeaks.

• Common symptoms: clunks, vague steering, uneven tyre wear, instability under brakes.
• Service tips: inspect regularly, replace in pairs, torque at ride height, align wheels afterwards.
• Related components: front lower arms, stabiliser bars, rear lateral links, trailing arms, rear subframe mounts.

How do you know if a 2017 Legacy needs new suspension bushes?

Tell-tales include knocking over bumps, a floaty or wandering feel on the motorway, tramlining, and uneven tyre wear. A mechanic can lever-test the arms and spot cracked rubber or excessive movement. If a hydraulic bush has leaked, it will often leave a dark, oily stain.

How often should suspension bushes be replaced on a 2017 Legacy?

There’s no fixed interval, many last well past 100,000 km, but heat, age, and road conditions matter. In Australia and New Zealand, an annual inspection or every 20,000 km is a good rule. Replace when wear affects handling, alignment, or tyres.

Are polyurethane bushes a good idea for a daily-driven Legacy?

Poly bushes can tighten steering and reduce roll compliance, great for spirited driving. For a daily driver, OE-style rubber keeps things quiet and comfy. A mixed approach works well: poly for stabiliser bar D-bushes, rubber for main control arm and trailing arm bushes to maintain NVH comfort.
