Parts for your 2018 Mitsubishi Outlander-Control arms

2018 Mitsubishi Outlander control arms — what they do and when to replace them

Control arms absolutely are fitted to the 2018 Mitsubishi Outlander. Technical documentation confirms it: the Mitsubishi Motors Outlander ZK/ZL Workshop Manual lists a MacPherson strut front suspension with a lower control arm and ball joint, and a multi-link rear suspension that uses multiple control/lateral arms. This layout is also reflected in the Mitsubishi ASA electronic parts catalogue and independent repair references covering 2015–2020 Outlander models. So, control arms are very much relevant to any servicing or repair on a 2018 Outlander.

On this model, the front lower control arms tie the steering knuckle to the subframe, letting the strut move up and down while keeping the wheel’s geometry in check. The bushes in the arms soak up vibration and harshness, while the ball joint allows smooth pivoting for steering and suspension travel. Out back, the multi-link arrangement uses several arms to manage toe and camber changes through bumps and cornering. All of this keeps the Outlander tracking straight, braking confidently, and wearing tyres evenly.

For day‑to‑day ownership, it pays to keep an eye (and ear) on the control-arm bushes and ball joints. Australia and New Zealand’s mix of city streets, rural roads, corrugations and plenty of roundabouts can age rubber bushes and boots faster than expected. Most owners will see well over 100,000 km from original arms, but age, road grime, oil contamination, and heavy loads can shorten that. Any arm replacement should be followed by a proper four‑wheel alignment, and the pivot bolts must be tightened at normal ride height to avoid preloading the bushes. Quality parts, new hardware where specified, and replacing in axle pairs are all smart moves.

• Common symptoms: clunks over bumps, steering shimmy, vague turn‑in, uneven or rapid inner/outer tyre wear, pulling under braking, or perished/tearing bush and ball joint boots.
• Service tips: inspect bushes and boots at each service, especially after impacts, replace when there’s play, cracking, or torn boots, align the vehicle after any arm, bush, or ball joint work.

Popular questions about 2018 Mitsubishi Outlander control arms

Do all 2018 Outlanders have front and rear control arms?
Yes. The 2018 Outlander uses a front MacPherson strut with a lower control arm and a rear multi‑link setup with multiple arms. Different trims and engines share the same basic layout, so inspections and alignment checks apply across the range.

What are the tell‑tale signs my control‑arm bushes or ball joints are worn?
Listen and feel for clunks on sharp bumps, a wandering or nervous steering feel, and check for uneven tyre wear. Visual signs include cracked or oil‑soaked bushes and torn ball joint dust boots. If in doubt, get a technician to check for play with the wheels unloaded.

Do I need a wheel alignment after replacing control arms?
Definitely. Any change to arms, bushes, or ball joints can shift camber and toe, so a four‑wheel alignment is essential to protect tyres and restore straight‑line stability and steering feel.
