Parts for your 2013 Toyota Fortuner-Control arms

2013 Toyota Fortuner control arms — what they do and when to service them

Control arms are absolutely fitted to the 2013 Toyota Fortuner. Toyota’s own technical literature — including the Fortuner/Hilux AN60 Repair Manual, the New Car Features (NCF) guide, and the Toyota Electronic Parts Catalogue (EPC) — specifies a double‑wishbone front suspension (upper and lower control arms with a ball joint and bushes) and a rear live axle controlled by a four‑link layout (trailing control arms and a lateral rod). So control arms are very much relevant on this model, front and rear.

On this Fortuner, the control arms do the heavy lifting of locating the wheels while allowing the suspension to move. Up front, the upper and lower arms set camber and caster, keep the wheel hub planted, and carry the ball joint and bushes that let everything articulate smoothly. At the back, the trailing arms keep the solid axle centred and stable under load, towing, corrugations, and off‑road use. Healthy arms, bushes, and ball joints help it track straight, brake confidently, and wear tyres evenly — exactly what’s wanted on long Kiwi and Aussie roads or heading up a rutted access track.

As part of regular servicing, the control arms and their wear items (bushes and ball joints) should be inspected for play, torn dust boots, split or perished rubber, corrosion around sleeves, and impact damage. Typical lifespan varies with use, but many Fortuners see bushes or a ball joint needing attention between about 80,000–150,000 km, sooner with heavy towing, beach work, or rough roads. If replacement is needed, it’s smart to:

• Replace side‑to‑side on the same axle for consistent handling.
• Book a wheel alignment afterwards — camber/caster and toe will shift.
• Torque bush bolts at normal ride height to avoid preloading the rubber.
• Consider new cam bolts/eccentrics if the fronts are rusty or seized.
• Choose quality rubber bushes for ride comfort, polyurethane can add NVH.

Owners should watch for knocks over bumps, vague steering, tram‑lining, uneven tyre wear, or a pull under braking. After deep mud or beach runs, a rinse and a quick spanner check can save the bushes. If a WOF/reg check notes movement or perished rubber, sorting it promptly keeps tyres happy and the Fortuner feeling tight and safe.

What are the signs the Fortuner’s control arms or bushes need replacing?

Common giveaways include clunks over bumps, steering wander, a shimmy under braking, and uneven tyre wear on the edges. A mechanic may spot torn ball joint boots, cracked or oil‑soaked bushes, or movement when levering the arm.

If alignment won’t hold or it keeps chewing tyres, the arm assemblies, bushes, or ball joints are likely due.

How long do the control arm bushes and ball joints typically last?

It varies with use, but many see 80,000–150,000 km. Regular towing, corrugations, and beach work can shorten that. City and highway commuters often go longer, especially with gentle driving and clean environments.

Annual inspections during service are a safe bet, with extra checks after hard off‑road trips.

Can the bushes be replaced on their own, or is a complete arm needed?

Both options exist. The front arms can often take new bushes and ball joints, but if the arm is bent, corroded, or the ball joint is non‑serviceable, a complete arm is the better choice.

Complete arms can save labour and include fresh joints and bushes, separate bushes can be cost‑effective if the arm itself is sound.
