Parts for your 2007 Toyota Ractis-Wheel studs nuts

2007 Toyota Ractis wheel studs and nuts (wheelstudsnuts): what they do and how to look after them

Yes, the 2007 Toyota Ractis uses traditional wheel studs and nuts. Technical references back this up: the Toyota Ractis Owner’s Manual (2006–2010) calls out loosening and tightening “wheel nuts” during a tyre change, the Toyota Electronic Parts Catalogue (EPC) for Ractis NCP100/NCP105 lists Stud, Hub Bolt and Nut, Wheel components (common Toyota references include stud 90942-02049 and nut 90942-01058), and Toyota service literature specifies a typical wheel nut torque of about 103 N·m for this platform. So “wheelstudsnuts” are absolutely relevant on a 2007 Ractis.

On the Ractis, the studs are pressed into the hub, and the nuts clamp the wheel to the hub face. It’s a simple, durable setup that spreads load evenly, keeps the wheel centred on the 4x100 PCD, and makes wheel swaps quick. Threads are M12 x 1.5, and the nuts use a 60° tapered seat to match the standard steel and many alloy wheels.

As part of regular servicing, it’s smart to give the wheel studs and nuts a look whenever tyres are rotated or brakes are checked. They should be clean, straight, and free of rust, with sharp, undamaged threads. Nuts should spin on by hand for several turns, if they bind, the threads may be stretched or cross-threaded. Don’t lube the threads or seats—oil or anti-seize can alter clamping force and lead to loose wheels.

Tightening matters. Use a torque wrench and a star pattern, finishing at about 103 N·m. After any wheel-off job, recheck torque after 50–100 km—especially if the car’s been on corrugations or motorway work. Rattle guns are handy, but final torque should be by hand.

Replace parts when they’re dodgy. A nut with a chewed seat or damaged thread is cheap to bin. A stud with rolled or stretched threads, obvious rust pitting, or that won’t hold torque needs swapping. Quality OEM or reputable aftermarket parts are the go—stick with 60° conical-seat nuts unless the wheel design specifically requires mag or shank nuts.

• Typical signs it’s time to replace: nuts that won’t stay tight, visible thread damage, wheel vibration after correct torque, or a snapped stud.
• Basic stud replacement outline: remove the wheel (and often the calliper and rotor), press or drive the old stud out, draw the new stud in square using washers and a sacrificial nut, then refit and torque the wheel nuts. Take care not to load the hub bearing or nick the ABS ring.
• Service tip for Aussie/Kiwi conditions: if the Ractis sees beach runs or alpine roads, rinse the hubs and hardware and check more often—salt is brutal.

Popular questions

What’s the correct wheel nut torque for a 2007 Toyota Ractis?

For the Ractis (NCP100/NCP105), Toyota service information for this class of vehicle specifies around 103 N·m. Use a star pattern and a calibrated torque wrench, and recheck after 50–100 km.

If running aftermarket wheels, keep the same torque unless the wheel maker specifies otherwise, and always match the correct 60° taper nuts to the wheel seats.

Are Ractis wheel nuts the same as Yaris/Vitz?

Generally yes. The Ractis shares the platform with contemporary Yaris/Vitz models: M12 x 1.5 thread, 60° tapered seat, 4x100 PCD. Many use the same Toyota nut and stud families listed in the EPC.

Always confirm by VIN or checking the wheel seat style. Mixing shank/mag nuts with tapered-seat wheels (or vice versa) isn’t on and can cause loosening.

Can a single broken stud be replaced at home?

It can, with the right tools—jack, stands, torque wrench, and a way to press or draw the new stud into the hub. Often the brake rotor needs to come off for access.

If the hub won’t allow clearance for the new stud to slide in, the hub may need removal and a press. If unsure, a decent workshop can knock it over quickly without risking the bearing or ABS hardware.
