Parts for your 2016 Toyota Mark x-Wheel hubs

2016 Toyota Mark X – Wheel Hubs

Based on technical sources including the Toyota GRX130/GRX133 Series Repair Manual (Chassis – Axle and Suspension) and the Toyota Electronic Parts Catalogue, the 2016 Toyota Mark X is fitted with bolt-on wheel hub assemblies on all four corners. These unitised hubs incorporate the wheel bearing and an ABS encoder/reluctor interface. So yes—wheel hubs are absolutely relevant and used on this model.

The wheel hub is the solid mounting point that the wheel and brake rotor (disc) bolt onto. Inside the hub assembly sits a sealed, precision bearing that lets the wheel spin smoothly while carrying the vehicle’s weight. On the Mark X, each hub works hand-in-hand with the ABS/traction control system via a magnetic encoder and nearby wheel speed sensor, helping the car keep its cool in wet or slippery Kiwi and Aussie conditions.

Because they’re sealed units, Mark X wheel hubs don’t need greasing, but they do need a bit of attention at service time. A quick spin-check on a hoist, listening for a humming or growling note, and a feel for play with the wheel held at 12 and 6 o’clock goes a long way. Any roughness, looseness, ABS light flickers, or heat after a short drive is a red flag.

• Common symptoms: droning noise that changes with speed, steering wheel vibration, ABS warning, uneven tyre wear, or a wobble under braking.
• Typical life: often well past 150,000 kilometres, but rough roads, water ingress, big potholes, or over-tightened wheel nuts can shorten it.

If a hub needs replacing, stick with quality OEM-equivalent parts. The Mark X uses a bolt-on hub unit, so there’s no pressing bearings in and out of the knuckle on most variants—handy and consistent when done by the book. Always use new hardware where specified (especially axle nuts), keep the ABS sensor and tone area spotless, and torque everything to Toyota’s spec. Avoid hammering or prying on the hub face—it can damage the bearing or distort the mounting surface, causing brake pulsation.

After replacement, an alignment usually isn’t required unless suspension fasteners were loosened, but it’s smart to check tyre wear and road-test for noise. Finish by torquing the wheel nuts evenly to the factory figure and re-check after a few short trips.

Popular questions

How can someone tell if their 2016 Mark X wheel hub is failing?

Most drivers notice a low humming or droning that gets louder with speed and may change when turning slightly left or right. There might also be a faint vibration through the seat or steering, an ABS light, or uneven tyre wear. On a hoist, any roughness when spinning the wheel by hand or noticeable play at the hub points to a worn unit.

Do wheel hubs need regular maintenance on a Mark X?

The hub assemblies are sealed, so there’s no greasing. Maintenance is really inspection: listen for noise, feel for play, check for heat after a short drive, and keep the wheel speed sensor area clean during brake or suspension work. Correct wheel nut torque and avoiding kerb strikes helps hubs last longer.

Is a wheel alignment required after replacing a hub?

Generally no, because the hub is a bolt-on to the steering knuckle and doesn’t set alignment angles. If strut or control arm bolts were loosened, or if there’s any uneven tyre wear or steering pull, it’s wise to check alignment for peace of mind.
