Parts for your 2019 Mitsubishi Eclipse cross-Control arms

2019 Mitsubishi Eclipse Cross control-arms: what they do and how to look after them

Control-arms are definitely used on the 2019 Mitsubishi Eclipse Cross. Technical references from Mitsubishi list MacPherson struts up front with a lower arm (control-arm) and a multi-link rear suspension that uses multiple control-arms/lateral links. These details appear in Mitsubishi Motors AU/NZ specification sheets for the 2019 Eclipse Cross, the official Eclipse Cross workshop manual (Front Suspension Group and Rear Suspension Group), and the Mitsubishi ASA electronic parts catalogue, which lists front lower arm assemblies and rear control-arms for this model year.

On the 2019 Eclipse Cross, control-arms are the hinge points that let the wheels move up and down while keeping the geometry in check. Up front, the lower control-arm ties the hub to the subframe, with bushes to isolate vibration and a ball joint to allow steering and suspension travel. Down the back, the multi-link layout uses a handful of arms to set toe and camber so the SUV stays planted and rides smoothly. When the bushes or ball joints get tired, the steering can feel vague, the car may wander, and tyres can wear out faster than they should.

It’s smart to have the control-arms checked at every service or at least every 15,000–20,000 km. A tech will look for split or oil-soaked bushes, cracked ball-joint boots, play at the joints, and any bent arms from a kerb strike or a decent pothole. If an arm or bush is flogged out, replace promptly — it protects tyres, brakes, and the rest of the suspension.

• Common symptoms of worn control-arms on an Eclipse Cross:
  • Clunks over bumps, especially at low speeds
  • Shimmy under braking or vague steering on the motorway
  • Uneven or rapid tyre wear, pulling to one side, or a crooked steering wheel

Good workshop practice on this model includes tightening bush bolts at normal ride height (not with the wheels hanging), replacing any single-use hardware where specified, and doing a proper four-wheel alignment after the job. Rear multi-link arms often have camber/toe eccentrics that seize, so penetrating fluid and care save headaches. Genuine arms maintain the factory hydro-bush feel, but quality aftermarket options can be a sharp buy if they meet OEM spec. Replacing arms in axle pairs keeps the SUV’s handling balanced, and a quick recheck of torque and alignment after a few hundred kilometres is a tidy finishing touch.

Popular questions about 2019 Mitsubishi Eclipse Cross control-arms

How long do the control-arm bushes last?
In local conditions, many Eclipse Cross control-arm bushes last 80,000–150,000 km, but life varies with road quality and load. City kerbs, speed humps, gravel roads, and heavy towing can shorten their lifespan. Regular inspections during scheduled servicing are the best way to catch wear early.

Do you need a wheel alignment after replacing control-arms?
Yes. Any time a control-arm, bush, or ball joint is changed on the Eclipse Cross, a four-wheel alignment should follow. It sets camber and toe (particularly at the multi-link rear) and protects tyre life while restoring crisp steering feel.

Is it safe to drive with a worn control-arm or ball joint?
It’s not recommended. Worn bushes and joints can worsen quickly, affecting braking stability and tyre contact. If there’s clunking, wandering, or uneven tyre wear, it’s best to book the vehicle in promptly for inspection and repair.
