2014 Toyota Mark X wheel studs and nuts

For the 2014 Toyota Mark X (GRX130/135), wheel studs and nuts absolutely apply. Toyota’s Electronic Parts Catalogue for the GRX130 series lists a “stud, hub” and matching “wheel nut” for both front and rear hubs, and the Toyota Repair Manual for this chassis describes wheel installation using tapered-seat nuts on pressed-in studs. The Owner’s Manual also specifies tightening the wheel nuts to the factory torque. So, unlike some European models that use wheel bolts, the 2014 Mark X uses a traditional stud-and-nut setup on a 5-stud, 114.3 mm PCD hub.

On this Mark X, the studs are press-fitted into the hub flange and the tapered wheel nuts clamp the alloy or steel rim securely against the hub face. That clamping force is what carries the load, the hub spigot keeps the wheel centred. Keeping the studs and nuts in good nick is a big part of safe, quiet motoring.

As part of regular servicing or tyre rotations, it pays to give the studs and nuts a once-over. Threads should be clean, straight, and dry—Toyota service literature calls for no oil or grease on the threads or seats. If a nut feels notchy, is rounded, or its cap has swollen, bin it and fit a quality replacement. If a stud is cross-threaded, stretched, or spins in the hub, it needs replacing. A typical replacement involves removing the caliper and rotor, pressing the old stud out, and drawing a new OE-length stud in squarely—an easy job for most workshops.

When refitting wheels, use the correct 60-degree tapered-seat nuts (common Toyota size is M12 x 1.5, but confirm by VIN). Start threads by hand, nip them up in a star pattern, and finish with a torque wrench to the Mark X specification in the manual (many Toyotas of this class specify about 103 N·m—check the exact figure for the vehicle). After wheel or tyre work, recheck torque after 50–100 km. Avoid hammering them home with a rattle gun, if one’s used, always final-torque by hand.

Good habits help too:

• Inspect studs/nuts at every tyre rotation or service.
• Keep the hub face and wheel mounting face clean and free of paint flake or rust scale.
• Use genuine or high-quality aftermarket parts matched to the vehicle.

These simple steps, backed by Toyota’s repair guidance and parts listings for the GRX130, keep the Mark X’s wheels secure and trouble-free.

Popular questions

What size are the wheel studs and nuts on a 2014 Mark X?
Most 2014 Mark X models use M12 x 1.5 studs with 60-degree tapered-seat nuts on a 5x114.3 hub. Always confirm by VIN in the Toyota parts catalogue, as trim and market variations can exist.

What’s the correct torque for the wheel nuts?
Use the torque specified in the Owner’s Manual or Repair Manual for the GRX130 Mark X. Many comparable Toyotas specify around 103 N·m, but the safest bet is to follow the exact figure for the car and recheck after 50–100 km.

Can a single damaged stud be replaced without changing the hub?
Yes. In most cases the brake caliper and rotor are removed, the damaged stud is pressed out, and a new stud is pulled in squarely. Clearance behind the flange can be tight, a professional can handle it quickly and ensure the new stud seats fully.
