Parts for your 2013 Toyota Mark x-Wheel hubs

2013 Toyota Mark X wheel hubs — what they do and when to replace them

Yes, the 2013 Toyota Mark X absolutely uses wheel hubs. Technical sources including the Toyota Electronic Parts Catalogue (GRX130/135 series), Toyota Repair Manual (TIS service procedures for front and rear axle), and OE bearing supplier catalogues (NSK/KOYO hub unit bearings) all detail bolt-on hub assemblies front and rear. Toyota labels these components as “Hub Sub-Assy, Front Axle” and “Rear Axle Hub & Bearing,” typically with an integrated wheel bearing and ABS/VSC encoder ring.

On the Mark X, each wheel hub anchors the brake rotor and wheel, houses the wheel studs, and lets the wheel spin smoothly on its sealed bearing. The rear hub units also work with the ABS/vehicle stability system via a magnetic encoder, so a crook hub can trigger warning lights as well as that tell-tale hum. They’re sealed for life, so there’s no greasing—when they wear, they’re replaced as a unit.

Servicing is mostly about smart inspections. At regular brake services (say every 20,000 km), a tech should spin each wheel and feel for rumble, check for play at 12 and 6 o’clock, and look for rust tracking around the hub face. Coastal Aussie and Kiwi cars can get a bit of corrosion where the hub meets the knuckle, so a clean mating surface and a dab of anti-seize on reassembly goes a long way.

• Common signs a Mark X hub is on the way out:
  • Road-speed hum or growl that changes when turning
  • Play or notchiness when spinning by hand
  • Uneven tyre wear or heat at the hub after a drive
  • ABS/VSC light with rear encoder faults

1. When replacing, use quality hub assemblies suited to the GRX130. Cheapies can be noisy quickly.
2. Clean the knuckle and hub faces, torque all fasteners to the Toyota spec. If there’s a driveshaft nut (front), it must be set correctly—no rattle-gun guessing.
3. A wheel alignment isn’t always required, but it’s wise if the knuckle’s been disturbed.
4. Replace damaged studs and always torque wheel nuts properly to avoid warping rotors and stressing the new hub.

There’s no fixed replacement interval, many Mark X hubs run well past 150,000 km. But once noise or play shows up, sort it promptly to protect tyres, brakes, and safety systems. All of this aligns with Toyota’s service literature for the GRX130 platform and the design notes from hub-unit bearing manufacturers that supply Toyota.

Popular questions about 2013 Toyota Mark X wheel hubs

How long do wheel hubs typically last on a 2013 Mark X?

With good tyres, correct wheel-nut torque, and no pothole abuse, many Mark X hubs last 150,000–250,000 km. Coastal use, big wheels, or frequent kerb hits can shorten that. Inspect at each brake service and act on any rumble or play.

Is it safe to drive with a noisy wheel hub?

Best not. A humming hub can escalate to roughness and heat, which risks ABS faults, uneven braking, and—worst case—bearing failure. Keep trips short and book it in, replacing a hub early is cheaper than fixing collateral damage.

Do both hubs need replacing at the same time?

Not strictly. Replace the failed side, then assess the other. If kilometres are high or noise is present both sides, doing them in pairs can save labour and keep the car even and quiet.
