Parts for your 2016 Toyota Mark x-Control arms

2016 Toyota Mark X Control Arms (GRX130)

Control arms are absolutely used on the 2016 Toyota Mark X. Technical sources such as Toyota’s New Car Features (GRX130 chassis section), the Toyota Electronic Parts Catalogue for GRX130, and the Mark X Repair Manual identify a front double-wishbone suspension (upper and lower control arms) and a rear multi-link setup (multiple control arms/links). That means control arms are central to how the Mark X rides, steers, and keeps tyre contact consistent.

On this model, the control arms locate the wheels in the correct position and guide their movement through bumps and cornering. The bushes soak up vibration and allow controlled movement, while the ball joints let the arms pivot smoothly. When everything’s healthy, the Mark X feels planted, tracks straight, and wears tyres evenly—perfect for long Kiwi and Aussie kilometres.

Because these arms are constantly working, their bushes and ball joints do wear. Road corrugations, potholes, and coastal climates can speed that up. It’s smart to inspect them at every 10,000–20,000 km service or annually—especially if there’s any knock over bumps or the steering feels a bit vague.

• Common symptoms: clunks when turning or over bumps, steering wander, uneven or rapid inner-edge tyre wear, brake shimmy, and an alignment that won’t hold.
• Workshop tips: replace in pairs on the same axle where practical, torque all arm bolts at normal ride height, and carry out a full four-wheel alignment afterwards.

Many GRX130 front arms have ball joints integrated into the arm, Toyota’s service guidance typically prefers complete arm replacement for durability and correct geometry. Aftermarket bush kits exist, but pressing them in and out needs proper tooling and care to avoid arm distortion. Quality matters—OE or reputable aftermarket arms/bushes keep noise down and alignment stable.

If the Mark X does mixed city–motorway driving, owners can often see 80,000–150,000 km from original bushes, but cars on rougher roads may need attention sooner. During servicing, techs should check for torn dust boots, split or oil-soaked bushes, corrosion at mounts, and play at ball joints. Fresh arms or bushes, correctly torqued and aligned, bring back that sure-footed feel and protect those pricey tyres.

Popular questions about 2016 Toyota Mark X control arms

Does the 2016 Mark X have front and rear control arms?
Yes. The GRX130 runs a double-wishbone front end with upper and lower control arms and a multi-link rear with several arms that locate the hub. Both ends rely on bushes and ball joints to maintain geometry and ride quality.

How often should control arm bushes or ball joints be replaced?
There’s no fixed interval, but inspections every 10,000–20,000 km are wise. Many cars go 80,000–150,000 km before needing attention, depending on roads and load. Replace when there’s play, torn bushes, noise, or persistent alignment issues, and always follow with a wheel alignment.

Can just the bushes be replaced, or do the whole arms need changing?
It depends on the arm. Some Mark X arms have integral ball joints and are best replaced as complete assemblies for safety and longevity. Where separate bushes are available, pressing them in correctly requires proper tools, complete arms can be quicker and often more reliable.
