Parts for your 2021 Suzuki Splash-Control arms

2021 Suzuki Splash control arms — what they are and when to replace them

Control arms are absolutely relevant to the Suzuki Splash. Factory technical references — including the Suzuki Splash/Ritz service manual, Autodata’s suspension data, and platform-sharing documentation for the Opel/Vauxhall Agila B — specify a front MacPherson strut setup with a lower control arm (wishbone) and ball joint. The rear is a torsion-beam arrangement with trailing arms and bushes rather than traditional control arms. While the Splash wasn’t in global production by 2021, many cars on Aussie and Kiwi roads are registered or serviced in that year, and their suspension layout remains the same — so yes, control arms are used on the front of a 2021-registered Splash.

Up front, the lower control arm ties the wheel hub/knuckle to the subframe, letting the suspension move up and down while keeping the wheel located accurately. Its rubber bushes soak up vibration and road harshness, and the ball joint provides the pivot for steering and suspension travel. If the bushes crack or the ball joint wears, steering feel goes vague, tyres can wear unevenly, and clunks or knocks can appear over bumps or when braking.

For a 2021 Suzuki Splash, it’s smart to inspect the front control arms at every service or at least every 15,000 km/12 months. Look for split or oil-soaked bushes, torn dust boots, loose ball joints, and any bent arms from kerb hits. Pay attention to symptoms like:

• Clunking over speed humps or when braking and turning
• Uneven or rapid tyre wear on the inner/outer edges
• Steering shimmy, wandering, or a pull to one side
• Vibration through the wheel that doesn’t balance out

When replacement time comes, most owners opt for complete arms with pre-fitted bushes and ball joint — it saves mucking about with presses and ensures fresh components right across the arm. Replace in pairs left/right to keep handling even, and always book a proper wheel alignment after the job. Follow workshop guidance to tighten the arm bolts at normal ride height (not with the wheels hanging) to avoid preloading the bushes. Where the manual specifies new stretch bolts or nyloc nuts, use new hardware. Quality aftermarket arms built to OEM spec are fine for daily use, if the car cops rough roads or carries loads, consider upgraded bushes for durability, noting you may get a touch more NVH.

On Kiwi WOF or Aussie rego checks, excess play in the ball joint or perished bushes can be a fail item. Staying on top of control arm condition keeps the Splash tracking straight, protects tyres, and makes the steering feel tight and confident.

FAQs

Do all Suzuki Splash models have front control arms?

Yes. Technical literature for the Splash/Ritz platform specifies a front MacPherson strut with a lower control arm and ball joint across the range. The rear uses a torsion beam, so no conventional rear control arms there — just trailing arms and bushes.

How long do Splash control arm bushes and ball joints typically last?

On city and motorway use, many go 80,000–150,000 km. Frequent gravel roads, potholes, coastal corrosion, or oil contamination can shorten that. Inspect annually for bush cracking and ball joint play, and replace at the first signs of looseness or noise.

Do you need a wheel alignment after replacing control arms?

Definitely. Changing arms alters the position of the hub and can shift camber and toe. A post-repair alignment protects your tyres and restores straight-line stability and steering feel.
