Parts for your 2021 Mitsubishi Asx-Struts

2021 Mitsubishi ASX struts: what they do and how to look after them

Struts are absolutely relevant on the 2021 Mitsubishi ASX. Mitsubishi Motors Australia’s model specifications and factory service information, along with mainstream data services such as Autodata and parts catalogues from major shock/strut manufacturers, list a MacPherson strut front suspension on this model, with an independent rear setup using separate shock absorbers. That means the ASX runs struts at the front, not the rear.

On the front of the ASX, the MacPherson strut does double duty: it supports the vehicle’s weight via the coil spring and controls wheel motion with the internal damper. The strut also locates the hub assembly and helps maintain correct camber as the wheel moves, which is why healthy struts make such a difference to steering feel, braking stability and tyre life. When the front struts are in good nick, the ASX feels planted over corrugations and composed in quick direction changes.

Owners and workshops will spot tired struts by:

• Oil seepage down the strut body or perished dust boots
• Knocking over bumps, or a floaty, bouncy ride
• Nose-diving under brakes or longer stopping distances
• Uneven or feathered tyre wear on the front
• Steering that tramlines or feels vague on the open road

As part of regular servicing, a quick visual and bounce test at each visit is smart, and a more thorough inspection every 20,000–30,000 kilometres is sensible. In typical Aussie and Kiwi conditions, many ASX front struts last 80,000–150,000 kilometres, though rough roads or heavy loads can bring that forward. When it’s time, replace struts in pairs, then carry out a proper four-wheel alignment to reset camber and toe. It’s also wise to renew related bits while you’re there: top mounts and bearings, bump stops, dust boots and—if worn—stabiliser links.

Because front struts are under spring tension, safe removal needs a quality spring compressor and the right procedures, so the job’s best left to a licensed technician. They’ll torque fasteners correctly, clock the spring ends, and road test to confirm the ASX tracks straight, brakes cleanly and rides quietly. A fresh set of quality, OE-equivalent struts will sharpen turn-in, tidy up body control and help protect those front tyres and brakes for the long haul.

• Does the 2021 ASX have rear struts?
  No. The front uses MacPherson struts, while the rear has an independent suspension with separate shock absorbers. So if there’s a knock out back, you’re likely chasing a shock, bush or link rather than a rear strut.
• How long do ASX front struts typically last?
  Expect about 80,000–150,000 kilometres, depending on road quality, loads and driving style. If the vehicle sees rough rural roads or lots of stop-start city work, inspections and potential replacement may be needed sooner.
• Is a wheel alignment needed after strut replacement?
  Yes. Replacing front struts changes ride height and camber, which affects toe. A proper alignment right after the job prevents uneven tyre wear and restores crisp steering.
