Parts for your 2021 Mitsubishi Asx-Steering bushes

2021 Mitsubishi ASX Steering Bushes

Technical references confirm the 2021 Mitsubishi ASX uses steering bushes. The Mitsubishi Motors Service/Workshop Manual for ASX/RVR/Outlander Sport (Group 37 – Steering) shows the electric rack-and-pinion mounted to the front crossmember via rubber mounting bushes (“cushions”). The Mitsubishi ASA electronic parts catalogue lists these steering gear mounting cushions for the same platform years, and major aftermarket catalogues (e.g., SuperPro/Whiteline/Febest) publish replacement rack-mount bush kits for 2010–on ASX models, including 2021.

On the 2021 ASX, steering bushes sit between the steering rack housing and the subframe. Their job is to locate the rack securely while soaking up vibration and road shock, so the wheel feels settled and the car tracks straight. When these bushes age, harden, or split, the rack can shift slightly under load. The tell-tales are familiar to Kiwi and Aussie drivers: a dull clunk over potholes, vague on-centre feel, kickback through the wheel, or light wandering at highway speeds. Left too long, it can nibble at tyre wear and make the car feel less confidence-inspiring.

There’s no fixed replacement interval, but they deserve a look at each service—especially if the vehicle sees rough roads, corrugations, or carries extra front-end weight. A good rule of thumb is to inspect every 20,000–30,000 kilometres or annually, checking for cracking, perishing, or oil swelling from any leaks.

• Symptoms to watch: clunks over bumps, imprecise steering, increased vibration, or uneven front tyre wear.
• Service tips: keep fluids off rubber, fix any rack or engine oil leaks promptly, and recheck torque after suspension work.

When it’s time to replace, quality OEM-equivalent rubber restores factory refinement, while polyurethane options deliver a firmer, more direct feel—handy if the ASX regularly tackles rough rural roads or carries loads. Either way, correct installation torque and orientation matter to stop the rack “walking” in the mounts. Because the rack position can subtly change when bushes are renewed, a wheel alignment is recommended immediately after replacement.

Owners who also feel knocks through the column should have the intermediate shaft and column lower bush inspected at the same visit. Partnering fresh steering bushes with healthy tie-rod ends and sound control-arm bushes keeps the front end tight, tyres wearing evenly, and the ASX feeling tidy and predictable on NZ and Australian roads.

Popular questions

Do 2021 Mitsubishi ASX models actually have steering bushes?
Yes. The ASX uses an electric rack-and-pinion bolted to the front subframe with rubber mounting bushes. These cushions isolate vibration and keep the rack securely located, and they are replaceable components when worn.

How long do ASX steering bushes last?
Lifespan varies with conditions. On smooth metro commutes they can go many years, frequent gravel roads, heat, or fluid contamination can age them faster. Having them inspected at regular services—roughly every 20,000–30,000 kilometres—is a smart move, with replacement when cracking, hardening, or excessive rack movement is found.

Should they choose rubber or polyurethane replacements?
Rubber suits daily drivers wanting factory comfort and noise isolation. Polyurethane offers a firmer, more direct steering feel and better durability under harsh use, but can transmit a touch more road texture. Either option should be installed and torqued correctly, followed by a wheel alignment.
