Parts for your 2011 Toyota Mark x-Wheel hubs

2011 Toyota Mark X wheel hubs — fitment, purpose, and service tips

Based on technical sources including Toyota’s Electronic Parts Catalogue (EPC) for the X130 series (2011 MY) and the Toyota workshop manual sections titled Front Axle Hub and Rear Axle Hub & Bearing, the 2011 Toyota Mark X is fitted with bolt-on hub unit bearings at all four corners. Major aftermarket catalogues from bearing manufacturers such as NSK, Koyo, and SKF also list complete hub assemblies for GRX130/GRX133 variants, confirming wheel hubs are absolutely used on this model.

On the 2011 Mark X, the wheel hub is the bit that mates the wheel to the car, houses the sealed bearing, and carries the wheel speed (ABS) encoder. It keeps the wheel turning smoothly, holds the studs straight, and lets the suspension and brakes do their thing without drama. Most units are sealed-for-life bearings, so there’s no routine greasing. Instead, the hub assembly is replaced when wear shows up. Both RWD and AWD variants use bolt-on hub units, AWD fronts also carry a driveshaft through the hub.

What owners notice when a hub’s on the way out is fairly consistent: a hum that rises with road speed, play at the wheel, ABS lights from a faulty encoder, or uneven tyre wear. Leave it too long and it can affect braking feel and rotor alignment. Because the bearing is integrated, the fix is straightforward—swap the hub assembly—no pressing in and out on most versions.

When servicing a Mark X, a workshop will usually check for hub roughness, axle play, and any ABS sensor faults. If replacement’s needed, quality matters, genuine or reputable OE-equivalent hubs tend to last and keep road noise down. For AWD cars, the front axle nut must be tightened to the exact spec and replaced if the manual calls for it. For RWD, the hub bolts and brake dust shield alignment are the focus. A quick road test and scan for ABS data afterwards is smart practice.

Handy tips to keep things sweet:

• Rotate tyres and keep pressures right to reduce bearing load and noise.
• Avoid kerb hits, side loads can bruise a bearing.
• During brake jobs, don’t bash the hub face—keep it clean and flat to prevent rotor runout.
• Mind the ABS sensor and magnetic encoder ring, keep metal filings away.

Popular questions about 2011 Toyota Mark X wheel hubs

Do all 2011 Mark X variants use the same wheel hub assemblies?

Not quite. While the function is the same, part numbers can differ between RWD (GRX130) and AWD (GRX133), and sometimes by brake package or production date. The Toyota EPC breaks this down by VIN, so matching on variant is the safest bet.

If in doubt, a shop will check stud pattern, flange offset, ABS connector style, and whether there’s a driveshaft through the hub (AWD front) before ordering.

What are the tell-tale signs a Mark X hub bearing is failing?

A steady humming or droning that changes with speed, a rough feel when spinning the wheel off the ground, ABS or VSC lights, or measurable play at 12 and 6 o’clock are the common giveaways.

Left unattended, it can cause brake shudder, chewed-out tyres, and longer stopping distances, so it’s worth sorting promptly.

Can the Mark X hub bearing be greased or adjusted?

No. The hub unit is a sealed bearing with a set preload from the factory. There’s no adjustment or repack. Service is inspect-and-replace when worn, using correct torque on fasteners and, for AWD fronts, a new axle nut if specified.

Good installation practice—clean hub face, proper torque, and protecting the ABS encoder—goes a long way to a quiet, long-lived result.
