Parts for your 2014 Mitsubishi Asx-Control arms

2014 Mitsubishi ASX Control Arms — Purpose, Care, and Replacement

Control arms are absolutely used on the 2014 Mitsubishi ASX. Technical sources including the Mitsubishi Motors Workshop Manual for ASX/RVR/Outlander Sport (2010–2016, Group 33A Front Suspension and Group 34 Rear Suspension) and the Mitsubishi ASA electronic parts catalogue list front lower control arm assemblies (LH/RH) and rear multi-link arms for this model. The front end runs a MacPherson strut with a lower control arm and ball joint, while the rear is a multi-link layout with lateral arms that perform control-arm duties.

On a 2014 ASX, the control arms link the wheels to the body, guiding up-and-down movement while keeping alignment angles in check. The front lower arm houses bushings to isolate vibration and a ball joint to allow steering and suspension travel. Healthy arms and bushes keep the steering direct, tyre wear even, and braking stable. Worn bushes or a loose ball joint can make the car wander, clunk over bumps, or scrub tyres prematurely.

When servicing, it’s smart to inspect the control arms at each service interval or WOF/roadworthy check. Look for split or oil-soaked rubber bushes, torn ball joint boots, rust around mounting points, and any play. Australian and New Zealand roads, with corrugations and potholes, can accelerate bush wear, so higher-mileage ASX examples benefit from closer attention.

• Replace options: either press new bushes/ball joint into the original arm or fit a complete arm assembly. Complete arms save time and often include new bushes and a pre-fitted ball joint.
• Always torque fasteners at normal ride height and book a full wheel alignment after any arm work to protect tyres and restore handling.
• Consider replacing control arms in axle pairs if wear is similar side-to-side for balanced feel.
• Choose quality components (OE or reputable aftermarket) with durable rubber or upgraded elastomer bushes for longevity.

Tell-tale signs it’s time to act include steering shimmy at speed, knocking over speed humps, vague turn-in, and feathered or rapid inner-edge tyre wear. If there’s any free play at the ball joint or visible bush cracking, don’t delay—those parts are safety critical. With fresh arms and a proper alignment, the ASX feels tight, tracks straight, and treats its tyres kindly for many more kilometres.

Popular questions about 2014 Mitsubishi ASX control arms

How long do control arms and bushes last on a 2014 ASX?
Service life varies with driving and load. Many ASX control arm bushes go 80,000–150,000 km, but rough roads, heavy towing, and aggressive speed hump hits can shorten that. Regular inspections during servicing will pick up early cracking or movement before it affects tyres and alignment.

A full arm with new bushes and ball joint often restores factory feel for years. If one side is worn, the other may not be far behind.

What are the symptoms of a worn control arm or ball joint?
Common signs include clunks over bumps, steering that feels loose or wanders, uneven or rapid tyre wear, and instability under braking. You might also hear a creak when turning into driveways or see a torn ball joint boot.

If any play is found at the wheel during a suspension check, the vehicle should not be driven hard until repaired, as ball joint failure is a serious safety risk.

Should both front control arms be replaced together?
It’s not mandatory, but it’s often wise. If kilometres and conditions are similar on both sides, replacing arms as a pair keeps handling balanced and can save on duplicate labour and alignment time.

Whichever route you choose—single side or both—finish with a proper wheel alignment to lock in tyre life and steering precision.
