Parts for your 2012 Mitsubishi Outlander-Wheel studs nuts

2012 Mitsubishi Outlander wheel studs and nuts

Based on the 2012 Mitsubishi Outlander workshop manual (chassis and hub sections) and the Mitsubishi ASA electronic parts catalogue, this model uses pressed-in wheel studs with separate conical-seat wheel nuts on all hubs. It’s not a wheel-bolt system. Industry service data used in AU/NZ workshops backs this up and specifies a standard wheel nut torque in the ~100 Nm range for this vehicle.

On the 2012 Outlander, the wheel studs and nuts do the heavy lifting of clamping the wheel and brake rotor firmly to the hub. The studs are fixed in the hub, the nuts provide the clamping force. Proper clamping keeps the wheel true, protects the bearings, and stops the rotor from shifting under braking. Most 2012 Outlanders run a 5-stud pattern with M12 x 1.5 threads and a 60° tapered (conical) seat nut, always match seat type to the wheel design.

As part of regular servicing, it pays to give the studs and nuts a quick once-over. Look for stretched or damaged threads, rust pitting on exposed studs, and any nuts with rounded hexes or distorted seats. If a nut winds on roughly by hand, or a stud spins in the hub, it’s due for replacement. When fitting wheels, start all nuts by hand, then snug them in a star pattern before final torquing. Aim for about 100 Nm unless the service sticker or manual for your exact variant specifies otherwise. Recheck torque after 50–100 km, especially after tyre rotations or new wheel/tyre fitments.

• Don’t lubricate threads or seats unless the service info specifically calls for it—dry torque is expected and lube can over-stress studs.
• Use a torque wrench for final tightening, impacts are fine for removal but not for the last pass.
• Replace any swollen or capped nuts that won’t accept the correct socket size cleanly.

Replacing a damaged stud on an Outlander involves pressing or drawing the old stud out of the hub flange and pulling a new one in squarely with a stack of washers and a sacrificial nut or a press. If a stud has snapped, check the rest—over-torque or corrosion often affects more than one. Using quality, correct-seat nuts and OE-equivalent studs keeps the clamp load consistent and the ride drama-free.

Popular questions about 2012 Mitsubishi Outlander wheel studs and nuts

What’s the correct wheel nut torque?
For most 2012 Outlander variants, workshops in Australia and New Zealand use about 100 Nm as the final torque on clean, dry threads with conical-seat nuts. Always confirm against the owner’s manual or model-specific service data, and recheck after 50–100 km of driving.

How can someone tell a stud or nut needs replacing?
If a nut won’t start by hand, feels gritty, or needs force to wind on, the threads are likely damaged. Visible rust pitting, stretched or mushroomed stud threads, spinning studs in the hub, or rounded nut hexes are all red flags. Any time a stud snaps or a nut strips, replace the affected hardware and inspect the rest.

What size are the studs and nuts?
Most 2012 Outlanders use M12 x 1.5 studs with 60° taper-seat nuts and a 21 mm hex. Wheel and trim packages can vary, so the safest bet is to confirm by VIN or checking an existing nut’s markings before ordering replacements.
