2015 Subaru XV Control Arms: What They Do and When to Replace Them

Control arms are absolutely fitted to the 2015 Subaru XV (GP/GP7). Technical references that confirm this include the Subaru Workshop Manual for the XV/Crosstrek, which specifies a MacPherson strut front suspension with a lower control arm (often called the transverse link), and the Subaru parts catalogue listing complete front lower control arm assemblies with integral ball joints and bushes. At the rear, the XV uses a double-wishbone layout with lateral links that function as control arms as well. So yes—control arms are relevant on this model.

On the XV, the front lower control arms tie the steering knuckle to the front subframe, managing wheel location through the suspension travel and keeping alignment angles steady under braking, cornering and over bumps. The bushes soak up vibration and allow controlled movement, while the ball joint lets the hub pivot smoothly for steering. Healthy arms help deliver that planted Subaru feel and even tyre wear.

As part of regular servicing, it’s smart to visually check the bushes and ball joint boots every 20,000 km or at each service. Anyone who tackles corrugations, gravel, or beach access tracks in Aus or NZ should inspect more often—salt air and off‑road grit can accelerate wear. If replacing, torque all fasteners at normal ride height and always book a wheel alignment afterwards. Many workshops replace arms in pairs and use new self‑locking nuts and camber bolts if they’re corroded.

• Common signs it’s time: clunks over speed bumps, vague steering, shimmy on braking, uneven tyre wear, torn ball joint boots, or perished/cracked bushes.
• Repair options: press in new bushes (cost‑effective, needs the right tools) or fit complete arms with pre‑installed bushes and ball joint (quicker, great if hardware’s rusty).
• After any impact with a kerb or pothole, have the arms and alignment checked—bent arms can look subtle but play havoc with tyre life.

Genuine Subaru parts keep the factory feel, quality aftermarket arms and polyurethane bushes can sharpen response but may add a touch of NVH. For NZ WOF or Australian roadworthy checks, tidy bushes and tight ball joints will keep the XV compliant and confidence‑inspiring on long motorway runs and weekend adventures alike.

Popular questions about 2015 Subaru XV control arms

How long do the control arm bushes last?
On a 2015 XV, many owners see 80,000–150,000 km from the factory bushes. Frequent gravel driving, heavy loads, or coastal conditions can shorten that. If there’s shudder on braking or wandering at highway speeds, inspect sooner.

Do you need a wheel alignment after replacing control arms?
Yes—always. Changing arms or bushes alters camber and caster. A proper alignment protects tyres, sharpens steering, and gets the XV tracking straight again.

Can you replace just the bushes, or do you need the whole arm?
Both approaches work. Pressing in new bushes is cost‑effective if the arm and ball joint are still good. If the ball joint boot is torn, the arm is bent, or hardware is badly corroded, a complete arm assembly is the faster, cleaner fix.
