Parts for your 2013 Toyota Wish-Control arms

2013 Toyota Wish control arms: what they do and when to sort them out

Technical sources confirm the 2013 Toyota Wish uses front control arms. The Toyota Repair Manual for the ZGE20/ZGE21 series (2009–2017) specifies a MacPherson strut front suspension with a lower control arm and ball joint, while the Toyota Electronic Parts Catalogue (EPC) lists the “Front Lower Arm Sub‑Assembly” for this model. Rear suspension on most 2WD variants is a torsion beam (no traditional rear control arms), but the front lower control arms are absolutely part of the setup.

On a 2013 Wish, the front control arms (often called lower arms or wishbones) locate the front hubs and let the wheels move up and down while keeping alignment true. Each arm houses bushes to absorb vibration and a ball joint to pivot smoothly. Healthy arms mean stable cornering, even tyre wear, and confident braking on Kiwi and Aussie roads.

Servicing-wise, they’re not a frequent replacement item, but they do wear out with kilometres, potholes, and speed bumps. The usual suspects are cracked or torn bushes and loose or noisy ball joints. Left too long, you’ll cop rapid tyre wear and vague steering. A decent workshop can press in new bushes or fit complete arm assemblies, which is often quicker and cost-effective.

• Tell-tale signs they’re tired:
  • Clunks over bumps, knocking when braking or accelerating
  • Steering wander or tramlining, especially on the motorway
  • Uneven or feathered front tyre wear
  • Shudder under braking
• Good practice when replacing:
  • Choose quality arms/bushes that meet OEM spec
  • Tighten control arm bolts at normal ride height (vehicle on its wheels) to avoid bush preload
  • Always get a full wheel alignment straight after
  • Inspect sway bar links, strut tops, and inner/outer tie rods at the same time

How often? There’s no strict interval, but inspection every service or 10,000–15,000 km is wise. In many cases, arms last well past 100,000 km, rough roads, heavy loads, and city kerb strikes bring that number down. If the ball joint boot is torn or there’s play, replace the joint/arm promptly—it’s a safety item. For DIYers, use a ball joint separator (not a pickle fork unless replacing the joint), support the hub to protect the CV, and torque to spec from the Toyota manual. Otherwise, leave it to a trusted mechanic and enjoy a sharper, quieter ride.

Popular questions about 2013 Toyota Wish control arms

How can they tell if the control arm bushes or ball joint are worn?
A technician will road test for knocks and steering wander, then check for play with the wheel off the ground. They’ll lever the arm to spot bush movement and check the ball joint for axial or radial play. Cracked bushes, leaking ball joint boots, or uneven tyre wear are strong flags.

Do they need a wheel alignment after changing control arms?
Yes. Changing arms or bushes can shift camber and toe. A proper alignment resets everything so the Wish tracks straight and the new tyres don’t scrub out.

Should they replace just the bushes, or the whole arm?
If the arm is straight and only the bushes are worn, pressing in new bushes is fine. If the ball joint is also tired, or the arm is bent or corroded, a complete arm assembly is usually faster, often similar money on labour, and restores the lot in one go.
