Parts for your 2012 Mitsubishi Lancer-Wheel studs nuts

2012 Mitsubishi Lancer wheel studs and nuts

For the 2012 Mitsubishi Lancer (CJ/CF series), wheel studs and separate wheel nuts are absolutely relevant and fitted from factory. This arrangement is confirmed by Mitsubishi’s CJ/CF Workshop Manual (Wheels and Tyres section), the Mitsubishi ASA/CAPS parts catalogue, and the owner’s handbook tyre-changing instructions, which all show pressed-in hub studs with M12 x 1.5 wheel nuts. In other words, this Lancer uses studs and nuts, not European-style wheel bolts.

On this Lancer, the wheel studs are pressed into the hub flange and the conical-seat wheel nuts clamp the wheel to the hub face. The whole job of the assembly is reliable clamping: even load distribution, accurate centring of the wheel on the hub, and consistent torque retention through everyday driving, braking and cornering. Using studs and nuts also makes roadside wheel changes and workshop rotations quicker, because the studs help locate the wheel while the nuts are started by hand.

As part of routine servicing or any tyre rotation, the wheel studs and nuts deserve a quick check. Clean, undamaged threads, correct nut seat contact, and proper torque are the keys to keeping the Lancer’s wheels secure and vibration-free. If a nut has been over-tightened with a rattle gun, cross-threaded, or the stud shows stretching or damaged splines, replacement is the right move. A technician can press out a faulty stud and pull in a new genuine or quality aftermarket stud, front hubs require the brake rotor to come off, and rears are similar depending on disc or drum set-up.

• Always start wheel nuts by hand to avoid cross-threading, run them down evenly in a star pattern.
• Tighten with a torque wrench to the specification shown in the Lancer’s workshop manual or tyre placard, avoid “hammering” with an impact gun.
• Keep threads clean and dry. Lubricants or anti-seize on threads can distort torque and clamping force.
• Check nut seat style (60° taper) and thread pitch (M12 x 1.5). Mismatched nuts can damage wheels and studs.
• After wheel service or rotation, re-torque the nuts after 50–100 kilometres of driving.
• Replace any stud or nut with damaged, rusty, or stretched threads, if multiple are suspect on one hub, replace them as a set.
• Inspect the wheel’s seating faces and the hub face, remove corrosion to ensure proper clamping.

With the right parts and a proper torque routine, the Lancer’s stud-and-nut system stays safe, quiet, and drama-free for the long haul.

Popular questions about 2012 Mitsubishi Lancer wheel studs and nuts

What size are the wheel studs and nuts on a 2012 Lancer?
They’re M12 x 1.5 thread with 60-degree tapered-seat nuts, typically using a 19 mm hex. The Lancer CJ/CF platform is hub-centric and commonly runs a 5 x 114.3 mm PCD. Always confirm against the vehicle’s VIN and wheel type, especially if aftermarket wheels or lock nuts have been fitted.

When should Lancer wheel studs or nuts be replaced?
Any time threads are rough, rusty, cross-threaded, or a nut won’t hold torque, it’s time to replace. Also replace studs with damaged splines or visible stretch, and any nuts with deformed seats. After a severe impact from an over-enthusiastic impact gun, it’s prudent to inspect and replace affected hardware to protect the hub and wheel.

Should anti-seize be used on Lancer wheel studs?
No. The studs and nuts are designed to be installed dry and clean. Lubricants or anti-seize can lead to over-tightening at the specified torque, reducing safety margins. If corrosion is a concern, a light film of corrosion inhibitor may be used on the hub face where the wheel sits—never on the threads or nut seats.
