Parts for your 2017 Toyota Mark x-Wheel hubs

2017 Toyota Mark X wheel hubs

Technical confirmation: the 2017 Toyota Mark X (GRX130/133) is fitted with wheel hub assemblies on all four corners. Authoritative sources such as Toyota’s workshop manual for the Mark X GRX130 (Chassis sections: Front Suspension – Hub/Knuckle, Rear Axle – Carrier/Hub) and the Toyota Electronic Parts Catalogue for the 2017 model year list bolt‑on hub-and-bearing units with integrated wheel speed (ABS) tone features. So wheel hubs are absolutely relevant for this vehicle.

The wheel hub is the solid bit the wheel bolts to. It houses the bearing that lets the wheel spin smoothly, supports vehicle load, and provides the mounting face for the brake rotor. On the Mark X, the hub and bearing come as a sealed assembly, so when the bearing wears, the full hub unit is replaced. The rear hubs also work in tandem with the ABS and stability control via a tone ring and sensor pickup, helping the car keep its footing in the wet or on rough roads.

There’s no fixed replacement interval for hubs on a Mark X, many run well past 150,000 km if tyres are balanced, shocks are healthy, and wheel nuts are torqued correctly. That said, it’s smart to have the hubs checked at each service so small issues don’t become big bills.

• Common signs a hub or bearing is on the way out:
  • A humming or growling noise that rises with speed and may change when steering left/right.
  • Noticeable play when the wheel is rocked at 12 and 6 o’clock, or a rough feel when spun by hand (with the car safely lifted).
  • ABS or VSC warning lights, sometimes tied to damaged rear hub sensors or tone features.
  • Heat around the hub after a short drive, or uneven brake/tyre wear.
• Helpful maintenance tips:
  • Always torque wheel nuts to factory spec and avoid rattle‑gunning them tight.
  • Rotate tyres on schedule and avoid big hits on potholes and kerbs.
  • Keep hub and rotor mating faces clean to minimise brake judder.
  • During rear hub work, inspect the parking brake shoes and ABS wiring.

Replacement on a Mark X is typically a bolt‑off/bolt‑on job using a quality hub assembly. Because the unit is sealed, there’s no re‑greasing or bearing preload to set. Alignment usually isn’t required after a hub swap unless suspension arms are loosened or disturbed, if they are, an alignment check is a good shout. Many owners replace only the faulty side, but on higher‑kilometre cars it can be sensible to plan the opposite side soon after.

Popular questions about 2017 Toyota Mark X wheel hubs

What are the tell‑tale noises of a failing wheel hub on a Mark X?
A steady humming or droning that increases with road speed is most common. If the tone changes when gently weaving the car (load shifting side to side), that’s another giveaway. A harsher growl or vibration through the floor can indicate the problem’s advanced.

Do they need a wheel alignment after changing a hub?
Usually no. A hub swap doesn’t alter geometry. If any suspension arms or cam bolts were loosened, or if the steering wheel sits off‑centre after the job, book an alignment. Uneven tyre wear is also a sign to check it.

How much play is acceptable in a Mark X hub?
Practically none. Any detectable looseness at the wheel (with the car safely lifted) or a gritty feel when spinning indicates the bearing is done and the hub assembly should be replaced.
