Parts for your 1998 Mitsubishi Lancer-Wheel studs nuts

1998 Mitsubishi Lancer wheel studs & nuts — what they do and how to look after them

Wheel studs and nuts are absolutely relevant to the 1998 Mitsubishi Lancer. Technical sources including the Mitsubishi Lancer CE/CK workshop manual (front/rear hub and brake sections), the Mitsubishi ASA parts catalogue, and common service guides such as the Haynes Lancer manual all show press-in wheel studs on the hub flanges, secured with conical-seat wheel nuts (commonly M12 x 1.5 thread on most variants). In short: this Lancer runs studs and nuts, not wheel bolts.

On this model, the studs are splined and pressed into the hub from the rear, while the wheel nuts clamp the wheel to the hub face. That clamping force is what keeps the wheel located and the brake rotor firmly sandwiched, so clean threads and correct torque matter. Factory alloys and steelies on these cars typically take a 60-degree taper-seat nut, matching the nut seat to the wheel seat is essential to avoid fretting and loosening.

For servicing, a quick visual once-over at each tyre rotation goes a long way: look for rust trails at the stud base, stretched or flattened threads, seized or “swollen-cap” nuts, and any signs of cross-threading. Threads should be clean and dry—no oil or anti-seize unless a manufacturer procedure specifically says otherwise, as lubrication alters torque-tension. Refit wheels by hand-starting the nuts, then tighten in a star pattern with a torque wrench to the factory spec (typically around 90–110 N·m, check the exact figure for your variant). After wheel work, re-check torque after 50–100 km of driving.

If a nut won’t spin on by hand, stop—chase the threads or replace the damaged parts. Replace any stud that’s bent, stripped, heavily corroded, or has been over-torqued. A broken stud can often be swapped at home: remove the caliper and rotor (or drum), press or hammer the old stud out with care, and draw the new stud in square using a spacer stack and an old nut, or a proper press. Always use the correct knurl diameter and a quality, high-grade stud. If a stud spins in the hub bore or the hole is flogged out, the hub may need replacing.

Finally, match nut style to wheel type, avoid impact guns for final tightening, and keep a spare nut or two in the boot for roadside tyre changes. Treated right, the Lancer’s studs and nuts will quietly do their job for years.

Popular questions

What’s the wheel nut torque for a 1998 Mitsubishi Lancer?
Most 1998 Lancer variants are around the 90–110 N·m mark. Use a torque wrench, tighten in a star pattern, and re-check after 50–100 km. Always confirm the exact spec in the factory manual for the specific engine/trim and wheel type.

What size are the wheel studs and nuts on a 1998 Lancer?
Most use M12 x 1.5 thread with a 60-degree taper-seat nut. Some aftermarket wheels may require different seat styles, so always match the nut seat to the wheel’s seat profile and verify thread pitch before fitting.

Can a broken wheel stud be replaced at home?
Yes, with basic tools. The brake caliper and rotor (or drum) usually come off first, the damaged stud is knocked or pressed out, and a new stud is drawn in square. If the stud won’t bite or the hub bore is worn, the hub may need replacement—at that point a workshop visit is wise.
