Parts for your 2015 Mitsubishi Asx-Steering bushes

2015 Mitsubishi ASX steering-bushes: what they do and when to replace them

Based on Mitsubishi’s factory Workshop Manual for the ASX/RVR/Outlander Sport (Group 37 – Steering), the Mitsubishi ASA electronic parts catalogue (listing the steering gear “insulator”/mount bushes for GA-series ASX), and aftermarket catalogues covering 2010–2017 models, the 2015 Mitsubishi ASX is fitted with steering-bushes. These bushes sit between the electric power steering rack and the front crossmember, isolating vibration and keeping the rack located under load.

On this model, the steering-bushes (also called rack-mount bushes or steering gear insulators) are rubber cushions that help the ASX feel tidy on the road. They soak up road harshness, stop the rack shifting when the wheel’s turned hard, and keep steering feedback consistent. When they wear, the driver can cop a dull clunk over bumps, a vague on-centre feel, or a sense the rack is nudging fore–aft under quick inputs. Left too long, other components can cop extra stress.

For ASX owners, steering-bushes aren’t a routine “change by date” item, but they are worth a look as part of scheduled servicing—especially from around 60,000–80,000 km, sooner if the vehicle sees rough roads. A quick inspection can pick up perishing, cracking or excess rack movement. A technician may:

• Check for play while an assistant saws the wheel left–right with the engine idling.
• Look for rubber splitting, oil contamination, or offset/racked sleeves.
• Listen for clunks when loading the steering over speed humps or driveway entries.

Replacement is straightforward workshop work: support the rack, remove the mount bolts, swap the bushes, then torque everything to spec from the Mitsubishi manual. If the subframe is loosened or shifted, a wheel alignment check is smart. Most ASX owners stick with OEM-style rubber for comfort, performance options in polyurethane can sharpen steering feel, but may pass on a touch more road texture. If polyurethane is used, apply the supplied lube sparingly and recheck torque after a few hundred kilometres. Keep oils and solvents off rubber bushes to avoid swelling and premature wear.

Typical service guidance in Australia and New Zealand is to inspect the steering-bushes at regular services, act on any noise, movement or cracking, and replace in pairs. It’s a modest-cost repair that restores the planted, predictable steering feel the ASX is known for.

Popular questions about 2015 Mitsubishi ASX steering-bushes

Do 2015 ASX models actually have steering-bushes?
Yes. The 2015 ASX uses an electric power steering rack mounted to the front crossmember with rubber insulator bushes. This is shown in Mitsubishi’s Workshop Manual (Steering Group) and the ASA parts catalogue listings for the steering gear mounting insulators.

What are the signs my ASX steering-bushes need replacing?
Common signs include a dull clunk over small bumps, vague or wandering on-centre feel, and visible rack movement when the wheel is rocked at idle. Cracked or oil-soaked bushes, or a knock when loading/unloading the steering, are solid prompts to replace them.

How often should they be replaced, and what does it cost?
There’s no fixed interval—inspect from about 60,000–80,000 km and during any front-end work. Many last well past 100,000 km depending on roads and tyres. In Australia/NZ, parts usually sit in the modest bracket, with labour commonly around an hour or two. If the subframe is moved, budget for an alignment check.
