2020 Mitsubishi ASX Ball Joints — What They Do and When to Replace

Yes, the 2020 Mitsubishi ASX is fitted with ball joints. Technical sources that confirm this include the Mitsubishi Motors Service/Workshop Manual for ASX/Outlander Sport/RVR (Front Suspension—MacPherson strut with a lower arm ball joint), the Mitsubishi ASA electronic parts catalogue (listing the front lower arm/ball joint and steering knuckle interface for GG/GK series ASX), and major aftermarket fitment guides that supply ball joints or complete lower control arms for the 2020 ASX.

On the 2020 ASX, the front suspension uses a MacPherson strut layout. The lower control arm connects to the steering knuckle through a ball joint, which acts like a tough little pivot. It lets the front wheels steer left and right while the suspension moves up and down over bumps. Good ball joints help the ASX track straight, steer precisely, and keep tyre wear even. When they’re tired, drivers may notice clunks over rough roads, vague steering, or feathered tyres.

There’s no fixed replacement interval for ASX ball joints, they’re replaced on condition. During regular servicing—especially if the vehicle sees lots of city kerbs, potholes, or rough Kiwi and Aussie backroads—mechanics should check the joints for play, torn dust boots, rust staining, or dried-out grease. Once a boot splits, grit and water get in, accelerating wear. If there’s free play or the boot is split, it’s time to replace.

Depending on production spec and parts availability, the ASX may take a standalone ball joint or a complete lower control arm assembly that includes the joint and new bushes. Many owners opt for the full arm to refresh the handling and save time on the press work. Either way, quality parts and correct torque settings (from the Mitsubishi workshop manual) are a must.

After any front-end work like a ball-joint or control-arm swap, a wheel alignment is essential. That keeps steering centred and protects tyres. If the ASX starts knocking over speed humps, wandering on the motorway, or tramlining, put ball joints high on the inspection list and avoid long trips until it’s checked—excessive play can be a safety risk.

• Watch for: clunks, steering wander, uneven tyre wear, and squeaks on turns.
• Service tip: inspect boots every 10,000–15,000 km or at each scheduled service.
• Post-repair: always book an alignment and recheck fasteners after a short shakedown.

Popular questions about 2020 Mitsubishi ASX ball joints

How long do ball joints last on a 2020 ASX?
Service life varies with driving conditions. On mostly sealed roads, many last well past 100,000 km. Frequent gravel, potholes, heavy loads, or lifted suspension can shorten that. Regular inspections for boot condition and free play are the best guide.

Can just the ball joint be replaced, or is a full control arm needed?
Both options exist. Some suppliers sell a separate joint, others provide the complete lower control arm with a pre-installed ball joint and new bushes. If bushes are also worn—or tools for pressing are limited—a full arm can be the smarter, time-saving fix.

What symptoms point to worn ball joints on the ASX?
Common signs include a dull clunk over bumps, vague or wandering steering, uneven or feathered front tyres, and sometimes a squeak when turning slowly. If any of these pop up, get the front end inspected promptly.
