Parts for your 2005 Subaru Forester-Control arms

2005 Subaru Forester control arms — purpose, care, and when to replace

Control arms are absolutely fitted to the 2005 Subaru Forester. The Subaru Factory Service Manual (FSM) for the 2005 Forester (SG) details a MacPherson-strut front suspension with a front lower control arm (often called the “lower arm”) locating each front wheel. Subaru’s FAST parts catalogue lists complete front lower arm assemblies and associated bushes and ball joints for this model. General repair guides (e.g., Haynes/Gregory’s Forester manuals) also cover inspection and replacement of these components, confirming their relevance on this vehicle.

On this Forester, the front lower control arms connect the chassis subframe to the steering knuckle via rubber bushes and a ball joint. Their job is to keep the wheel precisely located through bump, braking, and cornering, controlling camber and caster while allowing the strut to move. At the rear, the car uses multiple links (lateral links and a trailing arm) that function as control arms for wheel location and alignment, even if Subaru names them differently in the catalogues.

Keeping control arms and their bushes healthy pays off in straight-line stability, crisp steering feel, and even tyre wear. During routine servicing, it’s smart to inspect the arm bushes for cracking, splitting, oil-soaked rubber, or excessive movement, and to check the ball joints for play. Kerb strikes and rough roads can bend arms or ovalise bush sleeves, so a quick look underneath at each service interval is well worth it.

Common signs it’s time to act include:

• Clunks over bumps, steering shudder, or vibration under braking
• Wandering or tramlining, especially at motorway speeds
• Uneven or rapid inner-edge tyre wear

When replacing, many owners choose new complete arms for convenience, but pressing in quality OEM-style rubber bushes is also fine if the arm itself is straight and sound. Polyurethane bushes sharpen response but can add NVH, choose to suit the car’s use. Always torque pivot bolts at normal ride height to avoid pre-loading the bushes, and follow factory torque specs. A wheel alignment is essential afterwards, as fore/aft bush compliance and ball joint position affect caster and toe. On higher-kilometre Foresters (and those that tow or see corrugated roads), proactive bush and ball joint refresh can transform the way the car tracks and brakes, making it feel tight and confident again.

Popular questions about 2005 Subaru Forester control arms

Does a 2005 Subaru Forester have control arms?
Yes. The 2005 Forester uses front lower control arms as part of its MacPherson-strut front suspension. This is documented in the Subaru Factory Service Manual and Subaru’s parts listings, which include complete lower arm assemblies, bushes, and ball joints.

How often should the control arm bushes be replaced?
There’s no fixed interval. Inspect the bushes and ball joints at each service. Many last 120,000–200,000 km, but vehicles that carry loads, tow, or see rough roads may need them sooner. Replace when there’s cracking, movement, or noise, or when tyre wear and alignment issues appear.

Do I need a wheel alignment after replacing control arms?
Absolutely. Changing arms, bushes, or ball joints alters geometry. A professional alignment ensures correct caster, camber, and toe so the Forester tracks straight and the tyres wear evenly.
