Parts for your 2018 Mitsubishi Asx-Ball joints

2018 Mitsubishi ASX Ball Joints — what they do and how to look after them

Based on technical references, the 2018 Mitsubishi ASX is fitted with ball joints. The Mitsubishi Motors ASX/RVR Service Manual (Front Suspension – Group 33A) specifies a MacPherson strut front end with a lower control arm and a ball joint at the steering knuckle. The Mitsubishi ASA electronic parts catalogue for GA/GC chassis lists front lower arm ball joint components, and mainstream aftermarket fitment guides (including well-known suspension brands) catalogue replacement ASX ball joints for this model year.

On the ASX, the ball joint is the swivelling pivot that links the front lower control arm to the steering knuckle. It lets the front wheels move up and down over bumps while still steering left and right, keeping alignment angles in check and the ride nice and predictable. Because it carries load and moves constantly, it’s a wear item that deserves a look during routine servicing.

Typical signs that an ASX ball joint is on the way out include clunks over bumps, vague or wandering steering, a knock when braking or turning at low speed, and uneven or feathered tyre wear. A split or weeping dust boot is an early warning — once dirt or water gets in, wear accelerates.

Good workshop practice is to inspect ball joints at every service or at least every 20,000 km: check the dust boot, listen for noise on a road test, and use a pry bar to feel for play with the suspension unloaded. Depending on the supplier, the ASX’s front ball joint may be available as a separate joint or supplied as part of a complete lower control arm assembly, many workshops prefer the arm assembly for longevity and to refresh bushes at the same time.

When replacement time comes, it’s smart to do both sides on the same axle, use new pinch bolts/nuts where specified, and torque everything at normal ride height. Always follow with a wheel alignment — any change at the joint or arm will nudge camber/caster and toe. In typical Aussie and Kiwi conditions, quality ball joints can last 80,000–150,000 km, but gravel roads, heavy loads, big potholes, or larger wheels can shorten that. Keeping tyres correctly inflated and shocks in good nick will help the joints live longer, and any curb strike or pothole hit is a good excuse for an extra suspension check.

• Watch for clunks, wandering, and uneven tyre wear.
• Inspect boots and play regularly, replace in pairs.
• Choose quality parts and finish with a proper alignment.

Popular questions about 2018 Mitsubishi ASX ball joints

How long do ball joints last on a 2018 ASX?
In normal city and highway driving, many last 80,000–150,000 km. Frequent gravel, potholes, or bigger/heavier wheels can reduce that. Regular inspections and keeping tyres and shocks in good order help them go the distance.

Are the front ball joints separate or part of the control arm?
Both options exist. Some suppliers offer a standalone joint, while others supply the joint pre-fitted to a new lower control arm. Workshops often choose the complete arm to renew bushes at the same time and save labour.

Do you need a wheel alignment after replacing ASX ball joints?
Yes. Any work on the control arm or knuckle can alter toe and camber. A post-repair alignment protects tyre wear and restores the ASX’s straight-line stability and steering feel.
