Parts for your 2015 Mitsubishi Lancer-Wheel studs nuts

2015 Mitsubishi Lancer Wheel Studs and Nuts

Referencing the Mitsubishi Motors Lancer CJ/CF Service Manual and the Mitsubishi ASA electronic parts catalogue for MY2015, the 2015 Mitsubishi Lancer is fitted with pressed-in wheel studs and separate wheel nuts (M12 x 1.5, 60° taper). Wheel bolts are not used on this model.

On the Lancer, the wheel studs are splined and pressed into the hub or rear drum/rotor hat, while the wheel nuts clamp the wheel to the hub. That clamping force is what keeps the wheel seated, maintains brake rotor alignment, and prevents vibration at speed. The conical seat of the nut matches the wheel’s taper to centre the wheel accurately, so it runs true and the tyres wear evenly.

As part of regular servicing, the studs and nuts deserve a quick once-over. Threads should be clean and dry, most factory torque values are specified for dry threads. Any nut with a chewed seat, rounded hex, or stretched feel should be replaced. Similarly, studs showing damaged threads, heavy rust, or that spin in the hub need attention. Replacement involves removing the wheel and brake rotor/drum, pressing or knocking the old stud out, and drawing the new stud in square with a spacer and sacrificial nut or a proper press tool.

Factory tightening torque for Lancer wheel nuts typically sits around the 88–120 Nm range depending on wheel/trim, technicians should confirm the exact figure in the service manual for the specific variant. A torque wrench is the go-to here. Impact guns can be used to snug, but final torque should be done by hand to avoid over-tightening, warping rotors, or stretching studs.

• After any wheel-off job or tyre rotation, recheck nut torque after 50–100 km.
• Keep threads dry, don’t oil or anti-seize wheel stud threads unless the service data specifically allows it.
• A light smear of anti-seize on the hub’s spigot can help prevent the wheel sticking, but keep it off the rotor face and studs.
• If multiple studs are damaged on one corner, consider a hub assembly refresh for long-term reliability.
• For aftermarket wheels, ensure M12 x 1.5 nuts with the correct 60° taper and seat depth are used.

Looked after properly, the Lancer’s studs and nuts handle Aussie and Kiwi conditions with no fuss, keeping the wheels secure and the ride smooth.

Popular questions about 2015 Mitsubishi Lancer wheel studs and nuts

What torque should the wheel nuts be tightened to on a 2015 Mitsubishi Lancer?
The typical factory torque window is around 88–120 Nm depending on wheel and variant. Using a torque wrench is best practice. After a tyre rotation or wheel service, it’s wise to recheck torque after 50–100 km. Threads should be dry unless the service manual states otherwise.

How does someone know a wheel stud needs replacing?
Tell-tales include damaged or flattened threads, a stud that spins in the hub, visible stretching, or rust pitting near the base. If a nut won’t run on smoothly by hand, don’t force it—replace the affected stud and nut to avoid a roadside headache.

Are aftermarket wheel nuts okay to use?
Yes, provided they match M12 x 1.5 thread, use a 60° conical seat, and suit the wheel’s seat depth. Quality steel nuts from known brands are preferred for daily use. Avoid mismatched seat types, as they can reduce clamping force and mark the wheel.
