Parts for your 2009 Subaru Impreza-Control arms

2009 Subaru Impreza Control Arms

Yes, the 2009 Subaru Impreza is fitted with control arms. Subaru workshop literature for the GE/GH series (MY2009) and OEM parts catalogues confirm a MacPherson strut front end with lower control arms (often called transverse links), and a rear multi-link/double-wishbone arrangement using lateral links and a trailing arm that function as control arms. So, control arms are absolutely relevant to this model.

On the Impreza, the front control arms tie the wheel hub to the chassis and guide the up‑and‑down motion of the suspension, keeping the wheel aligned through bumps, braking, and cornering. The arms pivot on bushings and connect to the steering knuckle through a ball joint, letting the wheel steer while staying planted. In the rear, the links manage toe and camber changes so the car tracks straight and feels sure‑footed.

As part of servicing, it pays to give the control arms, ball joints, and bushings a once‑over each 20,000–30,000 kilometres, or at least at every major service. Workshop checks typically include inspecting bushings for cracks or fluid loss (on hydraulic types), checking ball joints for play, and ensuring mounting bolts are torqued to spec. Alignment should follow any control arm or bushing work to keep tyre wear even and steering feel crisp.

Drivers often notice worn control arm parts as vague steering, clunks over bumps, or uneven tyre wear. If a bushing has torn or a ball joint has play, replace promptly—leaving it too long can chew through tyres and stress other suspension bits. Many owners replace arms in pairs (both fronts or both rears on the same axle) to keep handling balanced. On rusty cars, complete arm assemblies with pre‑pressed bushings and joints can save time compared with pressing components individually.

• Tell‑tale signs: clunking, knocking, steering wander, shimmy under braking, rapid inner/outer tyre wear.
• Good practice: quality OEM-equivalent arms or bushings, new hardware where specified, and a four‑wheel alignment after fitment.
• Torque fasteners at ride height to prevent bushing preload and premature wear.

FAQs

Does a 2009 Subaru Impreza have control arms?
It does. The model uses front lower control arms (transverse links) and a rear multi‑link/double‑wishbone set‑up with lateral links and a trailing arm acting as control arms.

How long do control arm bushings last on a 2009 Impreza?
Typically 80,000–150,000 kilometres, depending on roads, driving style, and load. Harsh surfaces and aggressive cornering shorten life, gentle highway use tends to extend it.

Should both front control arms be replaced at the same time?
It’s recommended. Replacing in pairs maintains even handling and braking feel, and it’s efficient if both sides show similar wear. Always follow up with a wheel alignment.
