Parts for your 2018 Suzuki Splash-Wheel hubs

2018 Suzuki Splash wheel hubs — what they do and when to replace them

Wheel hubs are absolutely used on the Suzuki Splash, including vehicles registered or referred to as 2018 models. Technical documentation such as the Suzuki Splash/Opel Agila B workshop literature (shared platform) specifies front hub/bearing units in the front knuckles and rear hub assemblies on the torsion-beam axle, with ABS encoder integration where fitted. OE parts catalogues and bearing manufacturers’ data (SKF, NSK/NTN, FAG) list complete hub/bearing units for both axles on the Splash/Agila platform, confirming the component’s relevance to this vehicle.

On the Splash, the wheel hub’s job is to support the wheel and brake assembly, carry vehicle load, and let the wheel spin smoothly via a sealed double-row bearing. Many variants have the ABS encoder built into the hub, so that wheel-speed data stays accurate for ABS and stability systems. Up front, the bearing is typically a press-fit in the steering knuckle with the hub flange seated through it, out back, most trims use a bolt-on hub unit or a hub integrated with the brake drum. Either way, they’re sealed-for-life bearings that don’t need greasing.

During regular servicing of a 2018 Suzuki Splash, it’s smart to:

• Road test for a speed-dependent hum or growl that changes when cornering.
• Check for play at the wheel (12–6 and 9–3 o’clock checks) and inspect for ABS faults.
• Spin each wheel off the ground to feel for roughness, notchiness, or drag.
• Inspect for seal damage, heat discolouration, or metal dust around the hub.
• Refit wheels and torque wheel nuts to the manufacturer’s spec.

Replacement is condition-based rather than time-based. If a hub is noisy, has play, or throws an ABS code, replace it promptly to protect tyres and brakes. On the Splash’s front end, pressing bearings in/out requires the right tools and support of the knuckle to avoid brinelling the new bearing. On the rear, a bolt-on hub/drum unit makes the job more straightforward, but still use a new stake/locking nut and follow tightening procedures. Always keep magnetic encoder faces clean and avoid striking or loading the inner race during installation.

Quality hubs from reputable brands are worth the spend, and an alignment check after front-end work helps keep the Splash tracking straight and the tyres wearing evenly.

FAQs

What are the common signs a Splash wheel hub is failing?
Drivers usually notice a humming or growling that gets louder with speed and may change when turning. There can be detectable wheel play during a shake test, ABS warning lights if the encoder or sensor signal is poor, and in some cases uneven tyre wear or a hot hub after a drive.

Do the hubs on a 2018 Suzuki Splash need greasing?
No. The Splash uses sealed-for-life bearings, so there’s no periodic greasing. During service, the focus is on inspection, correct wheel-nut torque, and protecting seals—avoid pressure-washing directly at the hub and don’t use magnets or metal tools on encoder faces.

Should both hubs be replaced at the same time?
Not necessarily. Replace the faulty side first after proper diagnosis. That said, on high‑kilometre vehicles or when labour overlaps (e.g., both rear hubs), some owners choose to do both sides pre-emptively for convenience and consistent performance.
