Parts for your 2007 Mitsubishi Lancer-Wheel studs nuts

2007 Mitsubishi Lancer wheel studs and nuts — what they do and when to swap them

Based on the Mitsubishi Lancer CH (MY02–07) and CJ (MY07–) workshop manuals, the Mitsubishi ASA electronic parts catalogue, and AU/NZ dealer service data, the 2007 Mitsubishi Lancer is built with pressed-in wheel studs and separate wheel nuts (not wheel bolts). These sources specify M12 x 1.5 threads and a wheel nut tightening torque of about 100 Nm (check your owner’s manual or tyre placard for the exact figure for your trim and wheels). So “wheel-studs-nuts” are absolutely relevant to this model.

On the Lancer, the studs are splined and pressed into the hub flange. The nuts clamp the wheel to the hub face, keeping the wheel centred and the brake rotor secure under load. It’s a simple, tough setup that makes wheel changes quick and helps protect the hub threads from workshop abuse.

Service-wise, keeping the studs and nuts in good nick is all about clean threads and correct torque. Tighten the nuts in a star pattern on clean, dry threads using a torque wrench, not a rattle gun. Over-tightening can stretch studs or dish alloy wheels, under-tightening can let the wheel fret and loosen. Most AU/NZ delivered 2007 Lancers run M12 x 1.5 studs, seat style depends on the wheel. Steel wheels typically use a 60° taper-seat nut, while many OEM alloys use a flanged or mag-seat nut with a captive washer. Always match the nut style to the wheel seat.

Replacement is straightforward. A damaged stud can usually be knocked out and a new one pulled in with a spacer and nut, some rear hubs may need partial disassembly for clearance. Replace any stud that’s cross-threaded, visibly necked, or badly corroded. Swap nuts that have mangled seats or won’t torque smoothly. Keep anti-seize off the threads unless a specific procedure and adjusted torque are stated in the service literature—Mitsubishi’s guidance is for dry torque.

• Good signs to check at every rotation: clean, undamaged threads, nuts run on by hand, even torque, no rust streaking at the wheel.
• Avoid chrome caps that spin, mixed nut styles, and wheel spacers without proper hub-centric support.
• If multiple studs are damaged, consider a hub replacement to save time and ensure integrity.

Popular questions

What’s the correct wheel nut torque for a 2007 Lancer?
Workshop and owner’s manual data for AU/NZ models call for roughly 100 Nm. Use a torque wrench on clean, dry threads and tighten in a star pattern. Check your specific trim and wheel type on the tyre placard or service manual to confirm.

What stud size and nut seat does it use?
The 2007 Lancer uses M12 x 1.5 studs. Seat style depends on the wheel: steel rims generally take 60° taper-seat nuts, many OEM alloys use a flanged or mag-seat nut with a washer. Always match the nut to the wheel seat to ensure proper clamping.

Can a single damaged stud be replaced?
Yes. A single stud can be pressed out and a new one installed without replacing the whole hub in most cases. If access is tight, the brake rotor and sometimes the hub may need to come off. If several studs are damaged or corroded, it can be more efficient to replace the hub assembly.
