Parts for your 2018 Subaru Xv-Wheel studs nuts

2018 Subaru XV wheel studs and nuts — what they do and how to look after them

Technical references confirm the 2018 Subaru XV (also known as Crosstrek) is built with wheel studs and lug nuts, not wheel bolts. Subaru’s 2018 XV/Crosstrek Service Manual (Wheels and Tires section) specifies M12 × 1.25 studs on a 5 × 100 hub pattern, with wheel nut tightening torque of 120 N·m. The Owner’s Manual for Australia/New Zealand also shows wheel removal/fitment steps using nuts on fixed studs. So, wheelstudsnuts are absolutely relevant on a 2018subaruxv.

On this XV, the studs are pressed into the hub and the nuts clamp the wheel (and brake rotor hat) firmly to the hub face. That clamping force is what keeps the wheel located, shares braking loads, and prevents vibration. Because the XV is an AWD with regular weekend duties on corrugations or coastal roads, correct torque and clean mating surfaces are vital to avoid fretting, loose wheels, or warped rotors.

As part of regular servicing or tyre rotation, it’s smart to give the wheel studs and nuts a quick once-over. Look for damaged threads, stretching (a “necked” stud), visible corrosion, or nuts with deformed seats. Subaru specifies a 60° tapered (conical) seat nut for the factory wheels, mixing mag/flat-seat nuts with tapered-seat wheels is a no-go.

• Always tighten to 120 N·m using a torque wrench, following a star pattern.
• Avoid lubricants, oil, or anti-seize on the threads or seats, torque values assume dry threads.
• Re-torque after 50–100 km any time wheels have been off (new tyres, rotation, brake work).
• If a nut feels gritty or binds, stop and chase the threads or replace the affected stud/nut.
• Clean the hub face and wheel mounting face to remove rust scale before refitting.
• Use a rattle gun only for removal, hand-start every nut and finish with a torque wrench.

Replacement is straightforward but precise: damaged studs are pressed out of the hub flange and new ones pressed in squarely. On some jobs the hub may need to come off for access, so watch ABS tone rings and wheel bearings. Quality M12 × 1.25 studs and matched tapered nuts from genuine or reputable aftermarket suppliers are recommended. Inspect at each tyre rotation (about every 10,000 km) and replace any suspect hardware—cheap insurance for wheel security and brake health.

Popular questions about 2018 Subaru XV wheel studs and nuts

Q: What’s the correct wheel nut torque for a 2018 Subaru XV?

The specified torque is 120 N·m on clean, dry threads and seats. Tighten in a star pattern, then re-check after 50–100 km if the wheel was recently removed. This helps settle the joint and keeps the clamping force even.

Avoid over-tightening with a rattle gun—excess torque can stretch studs, distort brake rotors, and make roadside removal a pain.

Q: How can someone tell if the XV’s studs or nuts need replacing?

Signs include cross-threading, visible corrosion, a stud that won’t hold torque, nuts with rounded hexes or swollen caps, and wheels that work loose. If a nut drags or won’t hand-spin freely onto the stud, retire the pair.

After any incident of a loose wheel or over-torque, inspect closely. It’s best practice to replace the affected stud and its nut together.

Q: Can anti-seize be used on Subaru XV wheel studs?

Best practice is no—Subaru’s torque values assume dry threads and seats. Lubricants reduce friction and can lead to over-clamping at the same torque reading, risking stud stretch or rotor distortion.

If corrosion is severe, address the cause: clean the faces, replace damaged hardware, and keep road salt/grime washed off in coastal or alpine conditions.
