Parts for your 2007 Subaru Outback-Control arms

2007 Subaru Outback control arms — what they do and how to look after them

Control arms are absolutely used on the 2007 Subaru Outback. Technical references including the Subaru Factory Service Manual for the BP/BL platform (MY2007), the Subaru Technical Information System parts catalogue, and widely used workshop guides (e.g., Haynes for Legacy/Outback 2005–2009) all show a front MacPherson strut suspension with a lower control arm (often listed as the “front arm”) and a multi-link rear setup with lateral links that function as control arms. So if someone’s chasing “2007-subaru-outback/control-arms”, they’re looking at the right component set.

On this Outback, the front lower control arms tie the hub/knuckle to the front subframe, setting and maintaining geometry like caster and camber while allowing up-and-down movement via rubber (often fluid-filled) bushes and a ball joint. At the rear, the multi-link arms control wheel alignment through the travel so the wagon stays planted under braking, cornering and towing. Healthy control arms help it track straight, protect tyres from scrubbing, and keep steering feel tidy on Aussie and Kiwi roads.

Tell-tale signs it’s time to sort the control arms include:

• Clunks over bumps, especially at low speed
• Steering shimmy, vague turn-in, or pulling under brakes
• Uneven or rapid tyre wear
• Cracked, torn, or leaking front rear-bush (many are hydraulic)

For servicing, a quick visual every service interval and a thorough check around 20,000–30,000 km is smart. Look for torn bushes, perished rubber, or play in the ball joints. In our conditions, front bush wear is common by higher kilometres or after a few hard knocks from potholes or kerbs.

When replacing, many owners choose complete control arm assemblies for a quicker, cleaner fix that includes new bushes and ball joint. Pressing in bushes is workable but needs proper tooling and care to seat them square. Replace arms in axle pairs when practical, torque fasteners at normal ride height, and always book a wheel alignment afterwards—on a symmetrical AWD Subaru, correct alignment protects tyres and keeps the drivetrain happy. Quality matters: stick with reputable OEM or premium aftermarket arms and bushes that suit local roads and loads (touring, towing, gravel).

Driving style and road quality play a big part in lifespan. Avoid heavy impacts, keep tyres inflated and rotated, and address any knocks early so worn bushes don’t cascade into tyre and brake issues.

Popular questions

Does a 2007 Subaru Outback have control arms?
Yes. The Subaru Factory Service Manual for MY2007 Outback (BP/BL) specifies a front lower control arm in the MacPherson strut setup, and the rear uses multi-link arms (lateral links) that perform the control-arm role. The Subaru parts catalogue lists these components for the 2007 model year.

How long do control arm bushes and ball joints last?
It varies with roads and driving, but many owners see 80,000–150,000 km before noticeable wear. Look for clunks, instability under braking, and uneven tyre wear. Regular inspections catch bush cracks or ball joint play before it affects tyres and safety.

Can the bushes be replaced, or is a full arm better?
Both are viable. Pressing new bushes into original arms can save money if you’ve got the tools. Complete arms with new bushes and a ball joint are quicker to fit and often make sense on higher‑km cars. Either way, finish with a proper wheel alignment.
