Parts for your 2020 Mitsubishi Asx-Sway bars & links

2020 Mitsubishi ASX sway-bars-&-links: what they do and when to service them

Based on technical references, sway-bars-&-links are fitted to the 2020 Mitsubishi ASX. The Mitsubishi Motors 2020 ASX/RVR/Outlander Sport Service Manual specifies a front stabiliser (sway) bar and stabiliser link rods in the Front Suspension section, with many variants also listing a rear stabiliser bar in the Rear Suspension section. This is mirrored in the Mitsubishi ASA/CAPS OEM parts catalogue entries for the GA/GS platform, and widely supported by professional fitment guides used in workshops across Australia and New Zealand. So, for servicing or replacement, sway-bars-&-links are absolutely relevant to the 2020 ASX.

On the road, the sway bar ties the left and right suspension together to resist body roll. That keeps the ASX flatter through corners, helps the tyres maintain grip, and settles the vehicle in quick lane changes or windy conditions. It’s a simple bit of kit that quietly does a lot for safety and confidence, especially on bumpy regional roads and tight city roundabouts.

The links are the short rods that connect the bar to the control arm or strut. They pivot on sealed ball joints or bushes, allowing movement without play. Over time, those joints and the bar’s D-bushes can wear, particularly with high kilometres, gravel roads, or coastal corrosion.

• Signs it’s time to look: low-speed clunks or rattles over bumps, extra body roll, vague steering feel, or visible split bushes/boots and looseness at the links.
• Inspection rhythm: check at each service (roughly every 10,000–15,000 km or annually). Look for torn dust boots, perished D-bushes, and any play at the link joints.

• Replacement tips: replace links in axle pairs, use new lock-nuts, and torque everything to the factory spec from the Mitsubishi manual. Final tighten with the suspension at normal ride height to avoid preloading rubber bushes.
• Workshop wisdom: penetrating oil helps with rusty hardware, quality OEM or premium aftermarket links with coated hardware and sealed joints stand up better to ANZ conditions. A wheel alignment isn’t usually required for link-only work, but a quick post-job check and road test are smart.

Keeping the sway-bars-&-links in good nick restores the ASX’s tidy handling and quiet ride. It’s a relatively quick job that pays off every time the road throws up a bend, a bump, or a gusty southerly.

Does the 2020 Mitsubishi ASX have front and rear sway-bars-&-links?

The 2020 ASX has a front stabiliser (sway) bar and links as standard. Many trims also have a rear stabiliser bar. Exact fitment can vary by market and specification, so a VIN check or a peek at the Mitsubishi service manual/parts catalogue will confirm what’s on a specific vehicle.

How often should sway-bar links be replaced on a 2020 ASX?

There’s no fixed interval. Inspect at each service and replace when there’s play, noise, or damaged boots/bushes. In typical Aussie and Kiwi use, links commonly last anywhere from 60,000 to 120,000 km, but rough roads, heavy loads, and coastal environments can shorten that window.

Do sway-bar link replacements require a wheel alignment?

Usually no, because links don’t set wheel angles. If other suspension fasteners are loosened, or if bushes were replaced and the ride height shifted, an alignment check is a good idea for best tyre wear and handling.
