2022 Mitsubishi ASX Control Arms: Purpose, Care, and When to Replace

Control arms are absolutely fitted to the 2022 Mitsubishi ASX. Technical references including the Mitsubishi ASX workshop/service manual (Front Suspension – MacPherson strut, Rear Suspension – multi-link), the Mitsubishi parts catalogue (listing front lower control arm assemblies and rear lateral links/arms), and data services such as HaynesPro/Autodata all identify front lower control arms (with bushes and a ball joint) and multiple rear control arms/links on this model. So, yes — control arms are relevant and used on the 2022 ASX.

On the front, the ASX runs a MacPherson strut setup where the lower control arm (often called a wishbone) locates the wheel, manages fore-aft and lateral loads, and allows the strut and hub to move through their travel while keeping geometry in check. At the rear, the multi-link arrangement uses several arms/links to keep the wheel planted, helping ride comfort and stability. The rubber bushes in these arms isolate vibration, while the front ball joint allows smooth steering and suspension articulation.

For ongoing servicing, it pays to have the control arms and bushes inspected at each service or at least every 20,000 km/12 months. Look for cracked or torn bushes, perished rubber, leaking ball joint boots, or any play. In Aussie and NZ conditions — lots of stop-start, speed humps, coarse-chip bitumen, and the odd gravel road — bushes can work hard and age faster. A good shop will also check for uneven tyre wear, which can hint at bush or ball joint wear even before clunks show up.

• Common symptoms: clunks over bumps, steering shimmy, pulling under braking, wandering at highway speeds, and feathered/uneven tyre wear.
• Quick visual checks: split bush rubber, off-centre arm position at rest, torn ball joint dust boots, or rust around arm mounts.

When it’s time to replace, many owners go for complete arm assemblies up front (new bushes and ball joint included) to save labour and ensure everything’s tight. Rear arms may be replaced individually depending on which bush has failed. Always request a four-wheel alignment afterwards — fresh bushes change geometry and you’ll want tyres wearing evenly. It’s best practice to tighten arm pivot bolts at normal ride height so the bushes aren’t preloaded. New nuts/bolts are recommended where the service manual specifies. If DIY-ing, use stands and the right pullers/press tools — otherwise, a trusted workshop is the safer bet. For WoF/roadworthy peace of mind, quality OEM or reputable aftermarket arms are the go.

Popular questions about 2022 Mitsubishi ASX control arms

How long do control arm bushes last on a 2022 ASX?
Typically 80,000–150,000 km, but it varies with driving and road quality. Lots of city kerb hits, rough backroads, or heavy loads can shorten their life. Regular inspections during services will catch early wear before it affects tyres or handling.

Do I need a wheel alignment after replacing control arms?
Yes. Any change to arms, bushes, or ball joints can alter camber and toe. A proper four-wheel alignment right after replacement protects tyres and restores crisp steering.

Can I just change one control arm or should I do both sides?
You can replace a single faulty arm, but many technicians recommend doing both sides on the same axle to keep handling balanced and avoid a quick follow-up repair. At minimum, match condition side-to-side and always align the vehicle afterwards.
