Parts for your 2020 Subaru Impreza-Suspension bushes

2020 Subaru Impreza suspension bushes — what they do and when to replace them

Suspension bushes are absolutely fitted to the 2020 Subaru Impreza. Subaru’s Factory Service Manual for the GK/GT platform and OEM parts catalogues list multiple rubber–metal bushes across the car: front lower control arm bushes, front and rear stabiliser (sway) bar D‑bushes, rear lateral link and trailing arm bushes, and rear subframe bushes. They’re a core part of the Impreza’s MacPherson‑strut front and double‑wishbone rear suspension.

On this model, the bushes isolate noise and vibration, keep alignment steady under load, and allow the arms and links to articulate smoothly. Good bushes mean the Impreza steers straight, brakes confidently, and rides quietly. Worn bushes can let the wheel alignment wander, chew out tyres, and add harshness.

As part of routine servicing, it’s smart to inspect the bushes every 10,000–15,000 km or at each oil service. Look for perished rubber, cracking, splitting, or oil contamination (engine oil and coolant accelerate rubber breakdown). Lever the arms gently to check for excess movement, and listen for clunks over speed humps. Typical lifespan is 80,000–150,000 km depending on climate, road conditions, and driving style.

• Common signs of worn bushes: steering shimmy or tramlining, clunks over bumps, vague turn‑in, uneven or accelerated tyre wear, and instability under braking.
• Service tips: avoid solvent‑based sprays on rubber
