Parts for your 2019 Subaru Impreza-Suspension bushes

2019 Subaru Impreza suspension bushes — what they do and when to replace

Suspension bushes are absolutely fitted to the 2019 Subaru Impreza. Technical sources including the Subaru Service Manual for MY2017–2020 Impreza (Chassis: Front/Rear Suspension) and Subaru parts catalogues list the front lower control arm bushes (including a hydro-filled rear bush), front and rear stabiliser (sway) bar D-bushes, rear lateral link and trailing arm bushes, and rear subframe bushes. Aftermarket catalogues from well-known brands for the 2017–2023 Impreza also supply direct-fit replacement bushes, confirming their presence across the platform.

On this Impreza, bushes isolate vibration, keep alignment stable, and let the arms articulate smoothly. They’re the quiet achievers that soak up harshness and help the car track straight, especially over coarse-chip and corrugated roads common in Australia and New Zealand. The hydro bush in the front control arm is tuned to curb brake shudder and sharpen steering feel, while stabiliser bar bushes trim body roll noise and keep the bar working efficiently.

Over time, rubber hardens, cracks, or separates from sleeves, and hydraulic bushes can weep fluid. When that happens, the Impreza can feel vague or develop shakes under braking. Typical signs include:

• Clunks or creaks over bumps or at low-speed steering
• Wandering or tramlining, especially on the motorway
• Uneven or rapid tyre wear at the shoulders
• Steering shimmy under light braking
• Visible splits, perishing, or fluid leaks from a bush

Good practice is to inspect bushes at every service or 10,000–15,000 km, using a lever to check for excess play and looking for cracks or leaks. Always torque suspension bolts at normal ride height, tightening with the wheels hanging can preload and prematurely tear the rubber. Avoid petroleum-based cleaners on rubber components.

When replacement’s due, it’s smart to do pairs on the same axle to keep handling balanced. Some front bushes press into the original arms, many workshops choose complete arm assemblies to save time and ensure a precise fit. After any bush work, a four-wheel alignment is essential to reset camber, caster, and toe. Owners can choose genuine-style rubber for OEM comfort, or quality polyurethane options for sharper response (with a mild increase in NVH). In mixed city–regional driving, factory bushes often last 80,000–150,000 km, but rough roads or performance tyres can shorten that window. Keeping tyres correctly inflated and rotating on schedule takes stress off the bushes and helps them go the distance.

Popular questions

How long do suspension bushes last on a 2019 Subaru Impreza?

In typical Aussie and Kiwi conditions, many see 80,000–150,000 km before notable wear. Hydro front control arm bushes can age sooner if the car regularly hits potholes or corrugations. Regular inspections catch issues early and can save tyres.

What are the signs the bushes need replacing on this model?

Clunks over speed bumps, vague steering, brake shimmy, and uneven tyre wear are the big giveaways. A visual check for cracked rubber or fluid weeping from the hydro bush is also a clear indicator it’s time.

Do they need a wheel alignment after replacing bushes?

Yes. Any time control arm or lateral link bushes are changed, alignment angles shift. A proper four-wheel alignment restores straight-line stability, even tyre wear, and sharp steering feel.
