2019 Mitsubishi ASX Control Arms — What They Do and When to Replace

Control arms are absolutely fitted to the 2019 Mitsubishi ASX. Technical sources including the Mitsubishi Motors Workshop Manual for ASX/RVR (2019) — Group 33 (Front Suspension) and Group 34 (Rear Suspension) — plus OEM parts catalogues used in dealerships and trade data platforms, specify a MacPherson strut front end with a lower control arm (wishbone) and an independent rear multi-link layout that uses lateral control arms/links. So, control arms are relevant to this model both front and rear.

On the ASX, the front lower control arm locates the wheel hub via an integral ball joint and two chassis bushes, managing steering geometry and keeping tyres planted over bumps and through braking. At the back, the multi-link setup uses several arms to control toe and camber as the suspension moves, which helps the ASX feel settled on rough Kiwi and Aussie roads.

Because control arms carry big loads, the rubber bushes and ball joints are the usual wear points. There’s no fixed replacement interval, but a quick check at each service (or every 12 months/20,000 km) is smart, especially if the vehicle sees corrugations, potholes or speed humps regularly.

• Tell-tale symptoms: clunks over bumps, steering shimmy, brake shudder that isn’t disc-related, uneven or rapid tyre wear, wandering or pulling, and visible bush cracking or ball joint play.
• Safety tip: excessive play can affect stopping distances and stability — don’t leave it.

• When replacing, many front arms come complete with new bushes and ball joint, which saves pressing work and ensures correct geometry.
• If fitting bushes separately, align any orientation marks and press only on the correct sleeves to avoid damage.
• Tighten arm-to-subframe bolts at normal ride height to prevent bush pre-load and early failure.
• Replace any single-use (torque-to-yield) bolts/nuts as specified in the workshop manual.
• Do both sides if wear is similar — it helps balance and tyre wear.
• Always get a wheel alignment afterwards, front toe and rear toe/camber can shift with new arms or bushes.

For coastal vehicles, add a look for corrosion at ball joint boots and hardware. Sticking to quality OEM-equivalent parts maintains ride comfort and handling, while tougher urethane bushes can sharpen response for those prioritising firmness over refinement.

Does the 2019 Mitsubishi ASX have control arms front and rear?

Yes. The front uses a MacPherson strut with a lower control arm and ball joint. The rear is an independent multi-link design that employs several control arms/links to manage wheel alignment through suspension travel.

How often should control arm bushes or ball joints be replaced on an ASX?

There’s no set kilometre limit. Inspect at every service or at least every 12 months/20,000 km. Replace if bushes are torn, cracked, leaking (if hydraulic type), or if the ball joint has play, the boot is split, or there are clunks and steering instability.

Do you need a wheel alignment after changing control arms on an ASX?

Absolutely. New arms or bushes can alter toe and camber. Book a proper alignment straight after the work to protect tyres and restore the ASX’s straight-line and cornering behaviour.
