Parts for your 2018 Toyota Crown-Control arms

2018 Toyota Crown control arms — what they do and when to sort them out

Yes, the 2018 Toyota Crown absolutely uses control arms. Technical sources including the Toyota Electronic Parts Catalog (EPC) and Toyota repair manual procedures for the S210 and early S220 series list front and rear suspension arms (front upper/lower arms and multiple rear links), confirming the Crown’s use of double-wishbone or multi-link geometry. Toyota’s launch material for the 15th‑generation Crown (S220, 2018) also notes a multi-link architecture with multiple arms per corner. So control arms are very much part of the Crown’s suspension hardware.

On this model, the control arms locate each wheel precisely relative to the body, controlling camber, caster and toe as the suspension moves. The arms pivot on rubber bushes to isolate vibration, while ball joints allow the hub to articulate smoothly. The result is confident steering feel, tidy tyre contact, and that plush-yet-planted ride Crowns are known for.

With age and Aussie/Kiwi road realities—potholes, corrugations, and the odd kerb—bushes can crack or soften, and ball joints can develop play. That leads to vague steering, shakes over bumps, or inner-edge tyre wear. A quick look under the car often tells the story: split ball joint boots, oil‑soaked or torn bushes, or rust on exposed hardware in coastal areas.

• Tell-tale signs it’s time: clunks on take-off or braking, wandering or tramlining on the motorway, shimmy through the wheel, uneven tyre wear, and pulling after hitting bumps.
• Inspection tip: check bush condition and ball joint play at each 20,000 km/12‑month service, or after any big pothole strike.
• Replacement advice: swap arms in axle pairs where practical, torque fasteners at ride height, and finish with a proper four‑wheel alignment.

When replacing, quality matters—factory-spec or reputable aftermarket arms with OE‑type bushes and ball joints will restore the Crown’s composure. Many bolts are high‑tensile, re-use is common, but follow torque specs and angle settings from the Toyota repair manual. After control arm work, a wheel alignment is non‑negotiable. If the car has Toyota Safety Sense, the workshop may also need to check or calibrate cameras/radar following alignment. For NZ WOF and Aussie roadworthy checks, healthy bushes and joints help avoid advisories and odd tyre bills.

Look after the arms and bushes, and the Crown rewards with quiet, precise cruising for many more kilometres.

Popular questions about 2018 Toyota Crown control arms

Does the 2018 Toyota Crown actually have control arms?
Yes. The S210 (late run) uses a double‑wishbone front and multi‑link rear, while the S220 (from 2018) uses a multi‑link layout front and rear. Toyota’s EPC and repair manual procedures list the relevant upper/lower arms and rear links, confirming control arms are used throughout.

How long do control arm bushes and ball joints usually last?
Many owners see 80,000–160,000 km, but lifespan depends on roads, loads, and driving style. Coastal environments and rough surfaces shorten life. Watch for clunks, vague steering, and uneven tyre wear—those are your early prompts to inspect.

Do I need a wheel alignment after replacing control arms?
Absolutely. Any change to arms, bushes or ball joints affects geometry, so a four‑wheel alignment is essential. If your Crown has Toyota Safety Sense, the workshop may also need to verify or calibrate ADAS sensors after alignment.
