Parts for your 2019 Mitsubishi Asx-Steering bushes

2019 Mitsubishi ASX steering-bushes: what they do and when to replace them

Yes—steering-bushes are used on the 2019 Mitsubishi ASX. Technical sources back this up: the Mitsubishi Motors Service Manual for ASX/RVR (2019, Group 37 – Steering) shows the electric rack-and-pinion steering gear mounted to the front crossmember via rubber “insulators” (rack mount bushes). Mitsubishi’s ASA parts catalogue for GA2W likewise lists “insulator, steering gear” components, and major aftermarket catalogues (e.g., Nolathane and SuperPro) offer rack-and-pinion mount bush kits for ASX models from 2010 onward.

On the ASX, the steering-bushes sit between the steering rack housing and the subframe. Their job is to hold the rack securely in place while soaking up vibration and road harshness. Good bushes keep the rack centred and stable so the front wheels track straight, delivering precise, confidence-inspiring steering without unwanted kickback.

Over time, rubber can harden, crack or soften—especially with age, heat, and oil contamination. When ASX steering-bushes wear, the rack can shift under load. That shows up as wandering on the motorway, a dull clunk over bumps, vague on-centre feel, or a thud when turning into driveways. Left too long, you can get accelerated tyre wear from subtle toe changes.

As part of regular servicing, it’s smart to visually inspect the rack mounts for cracking, deformation, or separation, and check for any rack movement while an assistant lightly turns the wheel with the vehicle safely raised. Because the 2019 ASX uses electric power steering, there’s no fluid to leak from the rack itself, but engine oil leaks can still attack the rubber—clean any contamination promptly.

Replacement is straightforward for a workshop: support the rack, remove the mounting brackets, swap the bushes (observing orientation marks), and torque the fasteners to factory spec. A wheel alignment is recommended afterwards, because even tiny shifts in rack position can affect toe. If chasing a firmer, more direct steering feel, quality polyurethane bushes are an option, they sharpen response but may pass a touch more noise and vibration compared with OEM rubber.

There’s no fixed replacement interval—bush life depends on kilometres and road conditions—but many owners see wear show up somewhere between 80,000 and 150,000 km. If the steering starts feeling loose or you hear knocks over corrugations, it’s time to get them checked.

• Common symptoms: clunking over bumps, vague straight-ahead feel, tramlining/wandering, visible bush cracking, or rack movement while steering.
• Good practice: inspect at major services, keep oil off the mounts, replace in pairs, and align the front end after replacement.

Popular questions

Do 2019 Mitsubishi ASX models actually have steering-bushes, or is it a sealed rack?
They do. The factory setup uses rubber insulators that mount the electric steering rack to the front crossmember. While some dealers may recommend whole-rack replacement, the rack-mount bushes themselves are serviceable parts and are available in OEM rubber and performance polyurethane.

How often should ASX steering-bushes be replaced?
There’s no set interval. Have them inspected during routine servicing—especially from about 80,000 km onward. Replace if there’s cracking, softness, or any sign the rack is shifting. Harsh roads and bigger wheels can shorten their service life.

Do you need a wheel alignment after replacing steering-bushes?
Yes, recommended. Even a small change in rack position can alter toe. An alignment locks in straight-line stability and even tyre wear after the bushes are replaced.
