2015 Toyota Mark X wheel hubs — what they do and how to look after them

Wheel hubs are absolutely used on the 2015 Toyota Mark X (GRX130/133). Toyota’s service literature (TIS) includes specific procedures for “Front Axle Hub” and “Rear Axle Hub and Bearing” for this model and year, and the Toyota Electronic Parts Catalog lists “Front Axle Hub Sub-Assembly (43550-xxxxx)” and “Rear Axle Hub & Bearing (42450-xxxxx)” for GRX130/133 variants. These sources confirm the Mark X employs bolt-on hub assemblies with integrated bearings and ABS tone functionality.

On a 2015 Mark X, the wheel hub assembly does the heavy lifting of keeping each wheel centred and spinning smoothly with minimal friction. It houses the bearing, carries the wheel studs, and provides the mounting face for the brake rotor. The ABS system reads wheel speed from the hub area, so a crook hub can trigger warning lights as well as noise and vibration. Both RWD and AWD Mark X variants use sealed unitised hubs
