Parts for your 2018 Mitsubishi Outlander-Wheel studs nuts

2018 Mitsubishi Outlander wheel studs and nuts: what they do and how to look after them

Based on Mitsubishi technical literature and parts references for the 2018 Outlander (factory Service Manual: Wheels and Tyres, and Mitsubishi Motors Electronic Parts Catalogue/ASA), this model uses pressed-in wheel studs on the hubs with separate wheel nuts to secure the wheels. That means wheel-studs-nuts are absolutely relevant to the 2018 Mitsubishi Outlander, front and rear. No wheel bolts here.

On the 2018 Outlander, wheel studs and nuts do the simple but critical job of clamping the wheel evenly to the hub. The studs are pressed into the hub flange, the nuts thread onto the studs, pulling the wheel up square against the hub face. When they’re clean, straight, correctly seated and torqued to the factory spec, they keep the wheel centred, prevent vibration, and handle the loads from braking, cornering and our rough Aussie and Kiwi roads.

During regular servicing or any wheel-off job (tyres, brakes, suspension), it’s smart to give the studs and nuts a once-over. Check for:

• Damaged or stretched threads, rust pitting, or signs of cross-threading
• Rounded nut hexes, incorrect seat type, or mismatched nuts
• Metal transfer on the seats, which hints at over-tightening

Replacement is straightforward: the old stud is driven or pressed out of the hub flange from the rear, and the new one is pulled in square using a suitable spacer/washer stack and a sacrificial nut, or pressed in if access allows. Take care not to disturb the hub bearing or ABS tone ring. Always fit the correct OE-equivalent stud and nut (thread pitch and seat style must match the wheel), and never mix mag-seat and tapered-seat hardware. If in doubt, match to the VIN via the Mitsubishi EPC or check the owner’s/service manual.

Best practice on reassembly:

• Clean the threads, assemble dry (no oil or anti-seize) unless the manual explicitly allows it
• Hand-start all nuts, snug in a star pattern, then torque to the factory spec with a calibrated torque wrench
• Recheck torque after 50–100 km following any wheel-off service

Avoid belting the nuts with a rattle gun for final tighten, it’s a quick way to stretch studs and distort wheels. If a stud is snapped or a nut won’t seat smoothly, replace the affected hardware before driving. It’s cheap insurance for wheel security, brake rotor alignment, and tyre life.

Popular questions about 2018 Mitsubishi Outlander wheel studs and nuts

What size are the wheel studs and nuts on a 2018 Outlander?
Most 2018 Outlanders use M12 x 1.5 wheel studs with matching wheel nuts. Seat style depends on the factory wheel design (typically a 60-degree taper for many alloys and steels). Always confirm against the owner’s manual or an OE parts lookup by VIN to be sure you’ve got the correct seat and thread.

How tight should the wheel nuts be?
Use the factory torque spec listed in the owner’s/service manual or the wheel/tyre placard. For many vehicles in this class it’s around the 100–135 N·m range, but don’t guess—use the exact figure for your variant. Tighten in a star pattern with a torque wrench and recheck after 50–100 km.

Can I drive with a broken wheel stud?
It’s not recommended. One missing or damaged stud increases the load on the others and can lead to more failures, wheel vibration, and brake issues. Replace any damaged studs and nuts promptly and torque correctly before normal driving.
