2015 Mitsubishi ASX Control Arms — What They Do and When to Replace

Based on Mitsubishi Motors’ workshop documentation for the ASX/RVR (GA2W/GA3W platforms, Front Suspension Group 33A and Rear Suspension Group 34) and parts catalogues commonly used in Australia and New Zealand (Mitsubishi ASA/OEM catalogues and major aftermarket listings), the 2015 Mitsubishi ASX is fitted with control arms: a front MacPherson strut layout with lower control arms and a rear independent multi-link arrangement comprising several control arms. So yes—control arms are absolutely relevant to this model.

On a 2015 ASX, the control arms are the unsung heroes of the suspension. Up front, the lower control arms locate the hub and strut, keeping steering geometry steady under braking, cornering and over bumps. Out back, the multi-link control arms manage wheel camber and toe changes so the tyres stay planted and wear evenly. Together, they help the ASX feel surefooted on city runs, open-road trips and rougher Kiwi and Aussie backroads.

As part of routine servicing, it’s smart to give the control arm bushes and ball joints a good once-over. Rubber bushes naturally harden and crack with age, heat and exposure to road grime, ball joints can develop play that shows up as vague steering or a front-end clunk. Techs typically look for split bushings, perished rubber, leaks from fluid-filled designs (if fitted), torn dust boots and any movement when the arm is levered under load.

• Common symptoms owners notice:
  • Clunks or knocks over speed humps and potholes
  • Vague steering feel or pulling under brakes
  • Uneven or rapid tyre wear
  • Shudder on take-off or mid-corner instability

When replacement time rolls around, many workshops fit complete arms that come pre-assembled with new bushes and a ball joint, which saves press-work and downtime. On the ASX, tightening the inner bushing bolts at ride height is important to avoid preloading new bushes. New hardware is recommended where specified, and a four-wheel alignment should follow any arm or bushing change to dial camber and toe back into spec.

Owners keen on a bit more precision can consider upgraded bush materials, but for daily driving and comfort the OEM-style rubber is a safe bet. Given typical Australian and New Zealand conditions—corrugations, coarse-chip seal and the odd kerb strike—having the control arms inspected every 20,000–30,000 km or at each major service keeps the ASX tracking straight and the tyres wearing evenly.

• Popular questions about 2015 Mitsubishi ASX control arms

Does the 2015 Mitsubishi ASX have control arms front and rear?
The 2015 ASX runs front lower control arms with a MacPherson strut, and a rear independent multi-link setup that uses several control arms. Both ends rely on arms and bushes to hold alignment under load.

How long do ASX control arm bushes and ball joints typically last?
In Aussie and Kiwi conditions, many see 80,000–150,000 km, but life varies with road quality, driving style and load. Regular checks pick up early wear so tyres and alignment aren’t sacrificed.

Do you need a wheel alignment after replacing control arms?
Yes. Any arm or bushing change can alter camber and toe. A proper four-wheel alignment ensures the ASX steers straight, feels settled and protects tyre life.
