2011 Toyota Mark X Wheel Hubs — Purpose, Care, and When to Replace

Technical sources including the Toyota Repair Manual for the GRX130/133 series (2009–2012) and the Toyota Electronic Parts Catalogue confirm that the 2011 Toyota Mark X is fitted with wheel hub assemblies at all corners. These are relevant service items: rear hubs are driven on RWD models, while AWD variants have driven hubs front and rear. Aftermarket hub-unit bearing catalogues from OEM suppliers (e.g., Aisin/NSK) also list integrated hub-and-bearing units for this model.

On a 2011 Mark X, the wheel hub is the bit that the wheel bolts to, it houses the bearing that lets the wheel spin smoothly, locates the brake rotor, and provides the mounting face for the wheel studs. Modern Toyota hub units also incorporate the magnetic encoder or tone ring for the ABS and stability control systems. In day-to-day driving this means less noise, better steering feel, consistent braking, and accurate ABS readings.

Wheel hubs aren’t a periodic replacement like oil or filters, they’re replaced on condition. Common reasons include bearing wear (age, water ingress, pothole strikes), damaged wheel studs, or ABS faults traced to the hub encoder. During regular servicing on a Mark X, a quick hub check is smart: rotate each wheel by hand for roughness, listen for humming that grows with road speed, and feel for play with the wheel lifted. Any movement at 12 and 6 o’clock is a red flag.

• Tell-tales of a crook hub: droning that changes when loading the corner, ABS or VSC lights, uneven tyre wear, hot hub after a drive, or metallic grinding.

Replacement is typically done as a complete hub-and-bearing assembly. Front hubs on RWD Mark X models are non-driven but still use a unitised bearing, rears are driven units bolted to the housing. On AWD variants the front hubs are driven too. Replacing just the bearing is often impractical without specialist presses and fixtures, and many units are sealed-for-life. Always follow the factory torque specs for hub bolts and axle nuts (where fitted), clean mating faces, and avoid striking the encoder ring. After installation, clear any ABS fault codes and road test for noise. With quality parts and proper fitment, a new hub should run quietly for many tens of thousands of kilometres.

Popular questions about 2011 Toyota Mark X wheel hubs

Do the front and rear hubs differ on a 2011 Mark X?
Yes. On RWD models the rear hubs are driven units that couple to the axle shafts, while the fronts are non-driven hub-and-bearing assemblies. AWD versions have driven hubs front and rear. Mounting and torque procedures differ, so always match the hub to the axle layout and follow the correct manual section.

Can the bearing be replaced separately from the hub?
On most Mark X variants the hub uses a sealed, unitised bearing. While some workshops can press bearings in and out, Toyota service procedures and most quality aftermarket suppliers recommend replacing the assembly as a unit for reliability, correct preload, and to protect the ABS encoder.

What symptoms mean the hub needs attention?
A rising-speed hum, play at the wheel when lifted, ABS/VSC warnings, or a hot smell from one corner point to hub trouble. If the noise changes when steering left or right at speed, that also hints at a failing bearing on the loaded side. Don’t put it off, a failing hub can affect braking and tyre wear.
