2018 Suzuki Splash Wheel Hubs: What They Do and How to Look After Them

Based on the Suzuki Service Manual for Splash/Ritz (K12B) front suspension and rear axle sections, the Suzuki Electronic Parts Catalogue (EPC), and major bearing manufacturers’ catalogues (FAG, NTN-SNR, SKF) that list hub/bearing kits for the model, wheel hubs are absolutely fitted to the 2018 Suzuki Splash. The front uses a hub and cartridge bearing in the steering knuckle, while the rear is a hub assembly (often integrated with the brake drum on some trims) with an internal bearing and, on ABS cars, an encoder ring. So wheel hubs are relevant for this vehicle.

On a 2018 Suzuki Splash, the wheel hubs are the bit that ties the rotating wheel to the car’s suspension, keeps things spinning smoothly via the bearing, and provides a solid, centred mount for the wheel and brake hardware. They cop Aussie and Kiwi road conditions daily—potholes, corrugations, kerb nudges—and still need to run silky-smooth at highway speeds.

• They carry the wheel load through a sealed bearing, controlling play and noise.
• They locate the brake disc (front) or drum (rear) and wheel studs for safe clamping.
• On ABS models, they carry the tone/encoder ring that the sensor reads for stability systems.

Servicing-wise, the hubs themselves are sealed-for-life, but routine checks pay off. At each service or tyre rotation, spin each wheel and listen for a rumble, feel for roughness, and gently rock the tyre at 12 and 6 o’clock to detect play. Inspect studs and nuts, and look for rust bloom around the hub spigot that can cause wheel vibration.

• Watch for: a speed-related hum that changes on gentle lane swaps, ABS warning lights, uneven tyre wear, a hot hub after a drive, or free play at the wheel.
• If replacing: use quality parts, renew the hub/axle nut, and torque to the workshop spec. Don’t hammer the hub, press from the correct bearing race to avoid brinelling. Clean mating faces, lightly anti-seize the spigot (not the studs), and ensure ABS sensor alignment and air gap are spot-on.
• After front hub or bearing work, a wheel alignment check is smart. Re-torque wheel nuts after 50–100 km of driving.

Front bearings on the Splash are typically a pressed cartridge in the knuckle with a separate hub flange, the rear is commonly a bolt-on hub or drum-with-bearing unit. Either way, once noisy or loose, replacement is the fix—there’s no repacking or adjustment on these sealed units.

Popular questions about 2018 Suzuki Splash wheel hubs

What are the classic signs a Splash wheel hub is failing?

Most drivers notice a droning or humming that rises with speed and often changes when gently weaving at highway pace. You might also feel vibration through the floor, pick up play when rocking the wheel at 12 and 6 o’clock, see an ABS light if the encoder ring or sensor signal goes off, or find the hub runs hotter than the others after a decent drive.

Uneven tyre wear and slightly longer braking distances can also pop up if the bearing has excessive play. If in doubt, get it checked quickly—bearings don’t heal themselves, and catching it early saves rotors, drums, and tyres.

Do the hubs need greasing or adjustment during servicing?

No. The Splash uses sealed hub/bearing units that are lubricated for life and aren’t adjustable. The best servicing approach is inspection: listen for noise, check for play, verify smooth rotation, and confirm the ABS sensor wiring is intact. Keep the hub face clean to help the wheel sit true, and always torque wheel nuts correctly to avoid bearing stress.

When a bearing gets noisy or loose, replacement of the affected hub or bearing assembly is the go—there’s no practical or reliable way to repack or tighten it.

How long should the wheel hubs last in Australia or New Zealand?

It varies with roads and driving style, but many Splash hubs will see 100,000–200,000 km. Rough surfaces, heavy loads, frequent kerb knocks, or water and mud crossings can shorten that. Quality tyres, correct wheel nut torque, and avoiding potholes where possible help extend life.

If you’re hearing a fresh hum or feeling play during a service check, don’t push on for months—timely replacement prevents collateral damage to brakes and tyres and keeps the ABS happy.
