Parts for your 2013 Subaru Outback-Control arms

2013 Subaru Outback control-arms: what they do and when to service them

Yes, the 2013 Subaru Outback is fitted with control-arms. Technical references including the Subaru Factory Service Manual for MY10–14 Legacy/Outback (Chassis: Front and Rear Suspension), Subaru OEM parts catalogues (Front Lower Arm Complete, Rear Lateral Links), and reputable aftermarket catalogues (e.g., Moog, Whiteline) all list front lower control-arms and rear control links for this model.

On this Outback, the front uses a MacPherson strut with a lower control-arm that ties the hub to the subframe, keeping geometry steady through bumps, braking and cornering. The arm’s bushings soak up vibration while the lower ball joint lets the knuckle pivot for steering. Out back, the multi-link arrangement uses lateral links (effectively control-arms) to locate the wheel and maintain toe and camber as the suspension moves. Together, these parts keep the car tracking straight, ensure even tyre wear and preserve that surefooted Subaru feel on wet Kiwi or Aussie roads.

As part of routine servicing, it’s smart to inspect the control-arm bushes and ball joints every 20,000 km or at each WOF/reg service. Look for cracked or leaking (hydraulic) bushes, torn dust boots, play in the joint and any rust around mounting points. Typical giveaways include:

• Clunks over corrugations or speed humps
• Wandering steering, tramlining or a vague on-centre feel
• Uneven or rapid tyre wear, shimmy under braking or mid-corner instability

When replacement’s due, quality matters. Many front arms come with new bushes installed, the lower ball joint on this Subaru is a separate, replaceable part that seats in the knuckle. Press-in bushes can be done, but complete arms often save time and deliver a more consistent result.

Handy tips for the job:

• Torque bushing bolts at normal ride height to avoid preloading the rubber
• Replace both sides if wear is similar, and renew any tired sway-bar links or hardware you disturb
• Always get a four-wheel alignment afterwards—toe and camber can shift at both ends
• After 100–200 km, recheck fasteners and keep an eye on tyre wear patterns

Whether choosing OEM or a trusted aftermarket brand that meets local standards, sorting the control-arms restores crisp steering, better braking stability and longer tyre life—exactly what a well-kept 2013 Outback should deliver.

Popular questions about 2013 Subaru Outback control-arms

Do I need a wheel alignment after replacing control-arms on a 2013 Outback?
Yes. Changing control-arms or their bushes alters suspension geometry, so toe and often camber will shift. A proper four-wheel alignment ensures the steering’s centred, the car tracks straight and tyres wear evenly.

What are the common signs of worn control-arm bushes or ball joints?
Clunks over bumps, a floaty or wandering feel, shimmy under braking and uneven tyre wear are classic. Visual checks may show torn rubber, leaking hydro-bushes or a split ball-joint boot. Any looseness when levering the arm is a red flag.

Can I replace just the bushes, and how long do they last?
Yes—bushes can be pressed in, and the lower ball joint is a separate service item in the knuckle. Lifespan varies with roads and loads, but 100,000–160,000 km is common. Coastal exposure, heavy towing and rough tracks can shorten that interval.
