Parts for your 2015 Mitsubishi Asx-Strut mounts

2015 Mitsubishi ASX strut mounts

Based on technical sources including the Mitsubishi service manual for the ASX/Outlander Sport platform and major suspension catalogues from OE-equivalent suppliers (e.g., KYB and Monroe), the 2015 Mitsubishi ASX uses MacPherson struts at the front with dedicated strut mounts (also called top mounts/strut top with bearing). The rear of this model uses a multi-link arrangement with separate shocks and springs, so rear “strut mounts” aren’t applicable. That means strut mounts are absolutely relevant for the front suspension on a 2015 ASX.

On this ASX, the front strut mount does two big jobs: it isolates road noise and vibration from the body, and it allows the strut to pivot smoothly as the steering turns. Inside the mount is a bearing that lets the spring and strut rotate without binding. When healthy, the car steers cleanly, tracks straight, and rides quietly. When worn, it can creak, clunk, or cause notchy steering and odd tyre wear.

As part of regular servicing, a quick visual and hands-on check of the front strut mounts is smart, especially on vehicles that see rough roads or higher kilometres. There’s no fixed replacement interval, but many workshops start keeping a closer eye from about 60,000–100,000 km. If the bearing feels gritty, the rubber is cracked or separated, or there’s movement at the top hat when the steering is rocked, replacement is due. Because suspension works in pairs, replacing both front mounts together is the sensible call.

• Common symptoms of worn mounts:
  • Clunk or knock over speed bumps or driveway entries
  • Steering that doesn’t self-centre properly or feels notchy at low speed
  • Uneven or feathered front tyre wear, plus vague turn-in
• Service tips for the ASX front strut mounts:
  • Use a quality spring compressor and follow manufacturer torque specs for the top nut and mount hardware
  • Install the bearing in the correct orientation and check the upper spring seat isolator
  • Always book a wheel alignment after strut or mount replacement
  • Consider new dust boots and bump stops while the struts are out

OE-quality mounts maintain steering feel and NVH control. Done right, fresh strut mounts can make the ASX feel tighter, quieter, and more confidence-inspiring on Aussie and Kiwi roads.

Does the 2015 ASX have strut mounts front and rear?

Front, yes — MacPherson struts use a strut mount with a bearing. Rear, no — the ASX runs a multi-link setup with separate shocks and springs, so there’s no rear strut mount in the traditional sense.

What are the tell-tale signs the ASX strut mounts need replacing?

Clunks over bumps, creaks when turning, notchy or heavy steering at parking speeds, and uneven front tyre wear. If the top rubber is cracked or the bearing feels rough when the strut is turned, it’s time.

Is a wheel alignment required after replacing ASX strut mounts?

Yes. Any work that disturbs the strut assembly can shift camber/caster slightly. A post-repair alignment restores proper tyre wear and sharp steering.
