Parts for your 2015 Toyota Crown-Control arms

2015 Toyota Crown control arms — what they do and how to look after them

Based on Toyota’s technical literature for the S210-series Crown (model years 2012–2018), the 2015 Toyota Crown is fitted with control arms. The Toyota Repair Manual (TIS) details a front double-wishbone suspension (which uses upper and lower control arms) and a rear multi-link layout (which uses multiple control arms/links). Toyota’s Electronic Parts Catalog (EPC) for the 2015 Crown also lists “Arm Assy, Front Suspension Upper/Lower” and “Rear Suspension Arm Sub-Assy” entries. So, control arms are absolutely relevant on this model.

On a 2015 Toyota Crown, the control arms form the backbone of the suspension geometry. Up front, the double-wishbone setup uses upper and lower arms to keep the wheel tracking straight and true through bumps, braking and cornering. Out back, the multi-link arrangement uses several arms to manage camber and toe as the suspension moves, helping the big Crown feel planted and calm on Aussie and Kiwi roads.

Owners typically won’t replace control arms on a schedule, but they should be inspected at regular services. The rubber bushes and ball joints at each arm are wear items, over time they harden, crack or loosen, which can cause clunks over bumps, vague steering, a shimmy under braking, or uneven tyre wear. If those symptoms show up, it’s worth having a suspension specialist check for play in the joints and tearing in the bushes.

When it’s time for work, quality matters. Genuine Toyota arms or reputable aftermarket options with high-grade bushings and ball joints will restore the ride and steering feel the Crown is known for. After any arm or bushing replacement, a proper wheel alignment is essential to get camber, caster and toe back in spec and protect your tyres.

• Have the control arm bushes and ball joints inspected every 20,000–30,000 km or at each major service.
• Listen for knocking over speed humps, watch for feathered tyre edges, and note any steering wander — these are classic clues.
• Replace single worn components promptly, letting them go can stress other arms and chew out tyres.
• Torque fasteners with the vehicle at ride height, tightening with the suspension hanging can preload and tear new bushes.

Look after the Crown’s control arms and it’ll reward with quiet, confident handling and long tyre life — exactly what one expects from a premium Toyota sedan.

Popular questions about 2015 Toyota Crown control arms

How long do control arm bushes and ball joints last on a 2015 Crown?
In normal mixed driving, many last well past 100,000 km, but road conditions, loads and tyre choices can shorten that. Regular inspections catch early wear before it becomes a safety or tyre-wear issue.

Do I need an alignment after replacing control arms on my Crown?
Yes. Any change to arms, bushes or ball joints alters geometry. A four-wheel alignment will bring camber, caster and toe back to spec and protect your tyres.

Can I replace just the bushes, or should I fit complete arms?
Both approaches work. Pressing in quality bushes can be cost-effective, but complete arm assemblies save time and ensure fresh ball joints. Choice depends on condition, budget and workshop capability.
