2021 Mitsubishi Eclipse Cross Steering Bushes: What They Do and When to Replace

Yes, the 2021 Mitsubishi Eclipse Cross uses steering bushes. Technical references including the Mitsubishi Eclipse Cross Workshop Manual (Group 37/37A: Power Steering for GK/GL series, 2020–2022) and Mitsubishi’s ASA electronic parts catalogue for 2021 model codes GK1W/GK2W list the electric rack-and-pinion steering gear mounted to the front crossmember via rubber “steering gear mounting insulators” (bushes). There’s also a bush at the lower end of the steering column. These bushes isolate vibration, keep the rack securely located, and help deliver a precise, quiet steering feel on Aussie and Kiwi roads.

The purpose of these bushes is simple: they cushion the steering gear from road shock and engine/subframe vibration, while holding alignment so on-centre feel stays tight. When they harden, crack, or deform, drivers can notice knocking over small bumps, a vague or tramlining feel, or a clunk when rocking the wheel at standstill.

There’s no fixed replacement interval in the Eclipse Cross service schedule, so it’s a condition-based item. It’s smart to have them inspected at regular services, especially if the vehicle does high kilometres, sees rough roads, or has had fluid leaks nearby. Techs will look for perished rubber, oil swelling, excessive movement of the rack on the crossmember, and free play transmitted through the column.

• Common symptoms of worn steering bushes:
  • Clunking or thud through the floor on sharp bumps or driveway entries
  • Wandering or vague on-centre steering at highway speeds
  • Steering “kick” or buzzing over corrugations

Replacement is straightforward workshop work but does require supporting the subframe area and removing the rack fasteners. Marking the rack position, refitting with the correct orientation, and torquing mounts at normal ride height all help avoid pre-load. A wheel alignment is recommended afterwards, and some cars may need steering angle sensor calibration as part of the EPS system check. Quality OEM rubber bushes keep NVH civil, performance polyurethane options can sharpen response but may add a bit more road feel and noise.

To extend bush life: fix any powertrain fluid leaks promptly (oil can attack rubber), avoid hard kerb strikes, and rinse the underbody after beach trips. If a knock persists after bush replacement, have the tie-rod ends, lower control arm bushes, and stabiliser bar bushes checked too—those can mimic the same noises.

Popular questions about 2021 Mitsubishi Eclipse Cross steering bushes

Do all 2021 Eclipse Cross models have replaceable steering rack bushes?
All GK/GL-series Eclipse Cross models use rack mounting insulators as listed in Mitsubishi’s service literature and parts catalogue. Depending on VIN and rack supplier, the bush may be a separate insulator or integrated with a bracket, but it serves the same job and is serviceable when worn.

Will I need a wheel alignment after replacing the steering bushes?
Yes, it’s best practice. Disturbing the rack and subframe fasteners can shift toe slightly. An alignment and, where applicable, a steering angle sensor check will help the car track straight and keep driver aids happy.

How long do steering bushes usually last on an Eclipse Cross?
There’s no set lifespan, but many last well beyond 80,000–120,000 kilometres in normal use. Rough roads, kerb impacts, or oil contamination can shorten that. Replace based on noise, movement, or inspection findings rather than time alone.
