Parts for your 2022 Mitsubishi Asx-Strut mounts

2022 Mitsubishi ASX strut mounts — what they do and when to replace them

Based on technical sources — Mitsubishi Motors Service Manual for ASX/RVR/Outlander Sport (MY20–MY22, Group 33A Front Suspension) and major fitment catalogues from KYB and Monroe — the 2022 Mitsubishi ASX runs a MacPherson strut front suspension with an upper strut mount and bearing (often called a strut top or insulator). That makes strut mounts directly relevant to the front axle of this model. The rear uses separate shocks and springs, so there isn’t a rear strut mount in the same sense.

The front strut mount does two big jobs. First, it supports the vehicle’s front corner loads and lets the strut pivot smoothly when steering, thanks to its integrated bearing. Second, it isolates noise, vibration and harshness (NVH), keeping the cabin quiet and the steering feel tidy. When these mounts wear, the rubber can crack or collapse and the bearing can get notchy, which shows up as clunks over bumps, creaks when turning at low speed, vague steering, or cupped front tyres.

There’s no strict replacement interval, but on Aussie and Kiwi roads a practical approach is to inspect every service from about 40,000–60,000 km and plan replacement anywhere from 80,000–150,000 km depending on use, loads, and road quality. Many workshops recommend fitting new strut mounts (and bearings) whenever front struts are replaced, because access is the same and fresh mounts help protect the new dampers and restore steering feel.

• Tell-tale symptoms:
  • Clunk, thud or knock over speed humps and potholes
  • Creak or spring-bind feel when turning the wheel parked or at crawl
  • Steering wander or delayed response
  • Uneven or accelerated front tyre wear

• Service tips for a 2022 ASX:
  • Replace mounts in axle pairs for balanced feel
  • Use OE-quality mounts with the correct integrated bearing
  • Renew any single‑use/self‑locking nuts and follow factory torque specs
  • Get a wheel alignment after strut or mount work
  • Check upper spring seats and dust boots while you’re there

Look after the strut mounts and the ASX rewards with quieter running, sharper turn‑in and consistent braking stability, especially on corrugations and rough chip common across Aus and NZ.

Popular questions about 2022 Mitsubishi ASX strut mounts

Do all four corners of a 2022 Mitsubishi ASX have strut mounts?
No. The front suspension is MacPherson strut, so it uses strut mounts with bearings. The rear has separate shock absorbers and springs, so while there are upper shock mounts, they’re not “strut mounts”.

How long do ASX strut mounts usually last?
It varies with roads and loads, but many last 80,000–150,000 km. Frequent gravel or potholes can shorten life. If fitting new struts, it’s smart value to replace the mounts at the same time.

What happens if a strut mount is worn?
Expect clunks over bumps, creaking on steering, and a looser steering feel. Left too long, it can accelerate tyre wear and stress other suspension parts. Replacing the mount and bearing restores smooth steering and NVH control.
