Parts for your 2017 Mitsubishi Asx-Suspension bushes

2017 Mitsubishi ASX suspension-bushes: what they do and when to replace them

Suspension-bushes are absolutely fitted to the 2017 Mitsubishi ASX (also sold as RVR/Outlander Sport, GA2W/GA3W). Technical references back this up: the Mitsubishi Motors workshop manual (Front and Rear Suspension sections) specifies inspection and replacement of control arm and stabiliser bar bushings, the Mitsubishi ASA parts catalogue lists front lower control arm bushes, rear trailing arm and lateral arm bushes, stabiliser (sway) bar D-bushes and link bushes, and reputable aftermarket catalogues from SuperPro and Nolathane/Whiteline publish direct-fit bush kits for the 2010–2020 ASX range. So yes—suspension-bushes are relevant, and they matter.

On a 2017 ASX, suspension-bushes sit between metal components—control arms, subframe, stabiliser bars and links—to isolate vibration, keep alignment stable and let the arms pivot smoothly. They’re the quiet achievers that help the ASX steer straight, brake cleanly and ride comfortably on Aussie and Kiwi roads.

Over time, rubber bushes harden, crack or tear, especially the front lower control arm rear bush, rear trailing arm bush and the stabiliser bar D-bushes. Tell-tales include clunks over bumps, vague steering, shimmy under brakes, uneven tyre wear, or a squeak/creak from the front or rear. WOF/roadworthy inspectors often flag perished or oil-soaked bushes, and that’s the cue to act.

As a servicing guide, have all suspension-bushes visually checked at each 15,000–20,000 km service. Typical lifespan can be 80,000–150,000 km depending on road conditions, heat, loads and driving style. If one bush on a control arm has failed, many workshops fit a complete arm (bushes and ball joint pre-pressed) for reliability and time savings. Otherwise, pressing individual bushes is fine, but needs the right tools and technique.

• Best practice when replacing bushes:
  • Replace in axle pairs (both sides) to keep handling consistent.
  • Tighten pivot bolts at normal ride height to avoid preloading the rubber.
  • Book a four-wheel alignment straight after.
  • Follow the Mitsubishi manual for torque specs and any single-use fasteners.

Choosing materials? OEM-style rubber keeps the ASX comfy and quiet. Quality polyurethane can sharpen steering and resist oil/heat, but may add a touch of NVH—great for spirited drivers, less so if maximum comfort is the goal. Don’t lubricate factory rubber bushes, just keep them clean and free from oil. Poly bushes, however, usually require the supplied grease at install and occasional re-grease to stay silent.

If the ASX feels a bit wandery, crashes over potholes or chews through inner edges of tyres, fresh suspension-bushes can restore that planted, confident feel—and save those tyres.

Popular questions about 2017 Mitsubishi ASX suspension-bushes

How long do the ASX’s suspension-bushes last?
For most owners, expect somewhere between 80,000 and 150,000 kilometres. City kerbs, corrugations, heat and fluid contamination can shorten that window. Regular inspections during services catch cracks and tears before they affect tyres and braking feel.

Should bushes be replaced on both sides or just one?
It’s wise to do both sides on the same axle. Bush wear is usually symmetrical, and replacing in pairs keeps steering and braking behaviour consistent. If one control arm bush has failed, many techs recommend both arms or both bushes to avoid repeat alignments.

Rubber or polyurethane—what’s better for a daily-driven ASX?
Rubber is quiet and comfortable, ideal for daily commuting. Polyurethane offers sharper response and durability under heavy use, but can add a little vibration or road feel. Pick rubber for ride comfort, or poly if you want a sportier edge and don’t mind a hint more NVH.
