Parts for your 2014 Toyota Crown-Control arms

2014 Toyota Crown control arms — what they do and when to service them

Control arms are absolutely relevant on the 2014 Toyota Crown. Technical sources note the S210-series Crown runs a front double‑wishbone suspension and a rear multi‑link arrangement, both of which are built around multiple control arms and their bushings/ball joints. This layout is detailed in Toyota’s Crown (S210) New Car Features (NCF), the Toyota Repair Manual (Suspension – Front/Rear sections), and the Toyota Electronic Parts Catalogue for the 210‑series model range.

On the 2014 Crown, control arms locate the wheels under load, manage camber and caster as the suspension moves, and keep steering feel crisp. Bushings isolate noise and vibration, while ball joints allow smooth articulation. In the back, the multi‑link setup relies on several arms per side to control toe and camber, helping the big sedan feel planted at motorway speeds and tidy through corners.

For servicing, regular inspections of the control arms, bushings and ball joints are a smart move every 20,000–30,000 km or at each service interval—especially if the car sees rough chipseal, corrugations, or speed humps. Look for perished or cracked rubber, weeping hydraulic bushes (if fitted), torn dust boots, and play at the joints.

• Common signs of wear: clunks over bumps, wandering or tramlining, steering shimmy under braking, uneven or rapid tyre wear, and a slight pull or delay on turn‑in.
• Best practice on replacement: torque bush bolts at normal ride height, replace single‑use fasteners where specified, and book a four‑wheel alignment straight after.
• Parts choice: quality aftermarket or OEM arms are both fine, complete arms can be cost‑effective when ball joints are integral, while press‑in bushes suit targeted refreshes.

Front lower arms and their rear bushes cop most of the punishment and are often first to go, high‑mileage cars may also need rear toe and camber arms to tidy up alignment stability. Many owners choose to replace arms in axle pairs to keep handling balanced, though it’s not compulsory if only one side shows wear.

For long life in Aussie and Kiwi conditions, keep tyres correctly inflated, avoid prolonged curb strikes, and recheck alignment after any suspension work. Done right, fresh control arms restore that quiet, precise Crown ride and steering feel that the platform is known for.

Popular questions about 2014 Toyota Crown control arms

Does the Crown have rear control arms as well as front?
Yes. The 2014 Crown’s rear multi‑link suspension uses multiple arms on each side to control toe and camber. These rear arms are just as important as the front wishbones for stability and tyre life, and they benefit from periodic inspection and alignment checks.

How long do control arm bushes and ball joints typically last?
Service life varies with roads and driving style, but many Crowns see 80,000–160,000 km before noticeable wear. Frequent rough surfaces, heavy loads, or lowered suspension can shorten that window. Regular checks help catch small bush cracks or joint play early.

Will worn control arms cause uneven tyre wear or braking shimmy?
They can. Excess bush compliance or a loose ball joint lets alignment drift under load, scuffing tyres and sometimes causing a vibration when braking. Restoring tight arms and following up with a proper alignment usually clears those symptoms.
