Parts for your 2018 Suzuki Splash-Steering rack

2018 Suzuki Splash steering rack — what it does and how to look after it

Technical references confirm the Suzuki Splash is built with a rack‑and‑pinion steering gear. The Suzuki Splash Service Manual (A5D/A5E series), the Opel/Vauxhall Agila B Workshop Manual (its platform twin), and Suzuki’s Electronic Parts Catalogue all list a “steering gear (rack and pinion)” with tie rods for this model, with electric power assistance located on the steering column. So, even for a 2018‑registered Splash, a steering rack is absolutely relevant and fitted.

On the Splash, the steering rack converts the driver’s steering wheel input into precise left–right movement of the front wheels. The pinion on the column engages the rack bar, and the inner and outer tie‑rod ends transfer that motion to the hubs. Because this generation typically uses electric power steering (EPS) on the column, there’s no hydraulic pump, hoses or power‑steering fluid to service in the rack itself.

Day to day, the rack’s job is simple: keep the car pointing where it’s told, with consistent feel and minimal play. If the rack or its tie‑rod ends wear, the driver might notice wandering on the motorway, a vague on‑centre feel, clunks over bumps, or uneven tyre wear. Torn rack boots invite water and grit, accelerating wear — and in NZ/AU roadworthy checks, split boots or excess free play can earn a fail.

Good servicing for a Splash steering rack is mostly inspection‑based:

• At each service (or every 10,000–15,000 km), check rack boots for splits, moisture or grit inside, and ensure the clamps are tight.
• Check inner and outer tie‑rod ends for play and binding, replace in pairs if movement is detected.
• Listen for knocks when turning at low speed over broken surfaces, investigate promptly.
• Because the Splash uses EPS, there’s no power‑steering fluid to flush or top up.

If a rack needs replacing, expect the subframe/crossmember to be supported so the rack can be unbolted and swapped. Fresh lock‑nuts on the tie‑rod ends are a must, and a four‑wheel alignment is non‑negotiable afterwards to protect tyres and restore steering feel. Keep the steering wheel centred and the front wheels straight when setting toe. If any EPS components or the column are disturbed, a scan‑tool check for fault codes and a steering angle sensor zero‑point check are smart moves. Quality OEM or reputable aftermarket racks and ends are worth it — they’ll keep the Splash tracking straight and the tyres wearing evenly across plenty of Kiwi and Aussie kilometres.

• Popular questions about 2018 Suzuki Splash steering racks

Does a 2018 Suzuki Splash use power‑steering fluid?

No. Most Splash models of this generation use electric power steering (EPS) on the column, so there’s no hydraulic pump or fluid for the rack. If someone suggests a “power‑steering fluid flush” for a Splash with EPS, that service doesn’t apply. Focus instead on inspecting rack boots and tie‑rod ends.

How can someone tell if the rack or tie‑rod ends are worn?

Common clues include a loose or wandering feel on‑centre, clunks over bumps, steering that doesn’t self‑centre properly, or uneven tyre wear on the front. With the car lifted, any play when rocking the wheel at 3 and 9 o’clock points to inner or outer tie‑rod wear. A technician can confirm whether it’s the rack or the ends.

Is a wheel alignment needed after rack or tie‑rod work?

Absolutely. Replacing the rack or even just the tie‑rod ends changes toe. A proper four‑wheel alignment is essential to restore straight‑ahead tracking, steering feel and tyre life.
