Parts for your 2012 Subaru Impreza-Suspension bushes

2012 Subaru Impreza Suspension Bushes

Technical sources confirm the 2012 Subaru Impreza (GP/GJ) uses multiple suspension bushes. The Subaru Factory Service Manual for this generation lists front lower control arm bushes, rear lateral link and trailing arm bushes, and front/rear stabiliser (sway bar) D‑bushes and links in the Chassis – Suspension sections. Genuine Subaru parts catalogues and specialist catalogues from brands such as Whiteline and SuperPro also publish direct-fit bush kits for this model. That makes suspension bushes both relevant and serviceable components on the 2012 Impreza.

On a 2012 Subaru Impreza, suspension bushes are the quiet achievers. Pressed into arms and links, these rubber (or polyurethane) sleeves let the arms pivot smoothly while keeping noise and vibration out of the cabin. They also hold the wheel alignment steady under brakes and cornering, so the car tracks straight and feels planted. Typical spots on this model include the front lower control arm bushes (front and rear positions), stabiliser bar D‑bushes, rear lateral link bushes, trailing arm bushes, and crossmember/subframe bushes.

When bushes wear, the Impreza can develop clunks over bumps, a vague or wandering steering feel, shimmy under braking, and uneven tyre wear. Visual checks often show cracked, torn, or oil‑soaked rubber, or inner sleeves starting to separate. Because bushes carry geometry, it’s smart for any workshop to check them at each service, and especially whenever tyres, brakes, or alignment are being done. Many owners see 80,000–150,000 km from factory rubber, but rough roads, corrugations, big wheels, or spirited driving can shorten that window.

Replacement choices come down to comfort versus control. Genuine‑style rubber keeps NVH low and suits daily duty. Quality polyurethane sharpens response and lasts well, but can add a touch more road feel and noise—some drivers love that, others don’t. Either way, replace bushes in axle pairs for consistency. Press-fit bushes need proper tools and technique, torque all pivot bolts at normal ride height to avoid preloading, and book a wheel alignment straight after. Rusted sleeves and seized bolts are common on older cars, so allow time for careful removal rather than forcing components.

There’s not much to “maintain” beyond inspection. Avoid petroleum sprays on rubber. Keep underbody grime in check. If polyurethane bushes are fitted, a dab of the correct silicone-based grease during install and at long intervals helps keep them quiet. For owners chasing a tighter feel, adding fresh stabiliser bar D‑bushes and end links can deliver a noticeable lift without making the ride harsh.

• Inspect bushes at each service or at least every 20,000–30,000 km.
• Replace in pairs, torque at ride height, and align afterwards.
• Choose rubber for comfort, polyurethane for sharper handling.

How long do suspension bushes last on a 2012 Impreza?

Most see 80,000–150,000 km, depending on roads and driving style. City cars on good tarmac last longer, vehicles doing rural kays, corrugations, or carrying loads will wear bushes sooner. Any clunks, wandering steering, or uneven tyre wear are a cue to inspect and align.

Is it better to replace just the bushes or the whole control arm?

Pressing in new bushes is cost‑effective if the arm and ball joint are healthy. Many workshops opt for complete arms to save labour and avoid seized sleeves, plus you get a fresh ball joint. If the arm is straight and the joint is good, quality bushes alone are fine.

Are polyurethane bushes OK for WOF/roadworthy in NZ and Australia?

Generally yes, provided they’re a correct fit with no excessive play or fouling. WOF/roadworthy focuses on condition and secure mounting. Poly can add a bit more NVH, so owners should be comfortable with the feel and advise insurers of any modifications.
