Parts for your 1999 Mitsubishi Pajero-Wheel studs nuts

1999 Mitsubishi Pajero wheel studs and nuts

According to Mitsubishi’s Factory Service Manual for the late V20-series Pajero (1997–1999), the Mitsubishi ASA parts catalogue, and mainstream workshop guides (e.g., Haynes), the 1999 Mitsubishi Pajero uses wheel studs and nuts on a 6-stud (6x139.7 PCD) hub. The studs are M12 x 1.5 with conical-seat wheel nuts, confirming wheel-studs-nuts are very much relevant to this model.

On a 1999 Pajero, the wheel studs and nuts do the heavy lifting by clamping the wheel firmly to the hub so the braking and cornering loads transfer safely through the hub face. With a proper clamp, the wheel doesn’t fret or shift, which is especially important for a Pajero that sees corrugations, towing, or beach runs across Aotearoa and Australia.

For servicing, the focus is clean, correct, and consistent clamping. Tighten the wheel nuts in a star pattern and use a torque wrench, not just a rattle gun. Typical workshop specs for this era of Pajero list wheel nut torque in the 98–118 N·m range, always check the owner’s or service manual for the exact figure for the specific trim. Re-torque after 50–100 km whenever wheels have been off. Threads should be clean and dry—avoid lubricants or anti-seize on the threads unless the repair data specifically says otherwise, as lubrication alters the torque-tension relationship.

Replacement is straightforward when needed. Go new if any stud shows stretched or “necked” threads, if the stud spins in the hub, or if threads are crossed, rusty, or pitted. Replace nuts if the seats are damaged, the caps are swollen or distorted, or the hex is rounded. When pressing in new studs, make sure the knurl size matches the hub. It’s good practice to replace affected studs and nuts on the same hub together to keep clamping even.

• Check fitment details: 6x139.7 PCD, M12 x 1.5 thread, 60° conical-seat nuts (commonly 21 mm hex).
• Match the nut seat to the wheel seat. Aftermarket wheels can use different seats—conical vs. mag/flat—so don’t mix and match.
• If wheels are frequently removed for off-roading or tyre rotations, inspect studs and nuts each time for burrs and corrosion.

Handled with a bit of care and the right torque, the Pajero’s studs and nuts will hold up well to Kiwi and Aussie conditions, keeping tyres planted and adventures rolling.

FAQ: What’s the correct wheel nut torque for a 1999 Pajero?

Workshop literature for late-’90s Pajero models quotes a range around 98–118 N·m. Use a torque wrench and tighten in a star pattern. If the vehicle has aftermarket wheels or accessories, confirm the exact spec in the service manual for the specific variant.

FAQ: How can someone tell if a Pajero wheel stud needs replacing?

Look for damaged or flattened threads, visible stretching at the root of the threads, a stud that spins in the hub, or a nut that won’t run on smoothly by hand. Any of these signs means replace the stud, and often the corresponding nut too.

FAQ: Are the 1999 Pajero’s wheel nuts conical seat and M12 x 1.5?

Yes—technical parts catalogues list M12 x 1.5 studs with 60° conical-seat nuts on the 6x139.7 hub. Always ensure the nut seat type matches the wheel’s seat profile, particularly with aftermarket rims.
