Parts for your 2013 Subaru Outback-Wheel studs nuts

2013 Subaru Outback wheelstudsnuts: what they do and how to look after them

Based on the Subaru Factory Service Manual for the 2010–2014 Outback/Legacy platform, the 2013 Subaru Outback uses press-in wheel studs with tapered-seat wheel nuts (not wheel bolts). The Owner’s Manual and Subaru Genuine Parts catalogue both confirm a five-stud hub using M12×1.25 threads with 60° taper nuts. So yes—wheelstudsnuts are absolutely relevant and fitted to this model.

On this Outback, the wheel studs anchor into the hub and the nuts clamp the wheel and brake rotor firmly to the hub face. That clamping force is what keeps the wheel centred, prevents brake pulsation from rotor movement, and maintains safe, even loading on the bearings. Subaru specifies a 5×100 PCD and typically a 19 mm hex for the OEM nuts, with a dry-thread torque of about 120 N·m. The car relies on the studs’ strength and the nuts’ seat design to hold alloy or steel wheels snug without fretting.

As part of routine servicing, the wheelstudsnuts deserve a quick once-over. Any rust bloom, stretched or flattened threads, damaged nut seats, or a nut that binds before seating are red flags. After tyre rotations or wheel-offs for brakes, torque the nuts in a star pattern to 120 N·m on clean, dry threads and hub faces. It’s good practice to re-check torque after 50–100 kilometres of driving.

• Do not lubricate studs or nut seats unless a Subaru service bulletin explicitly calls for it, torque values assume dry threads.
• If a stud is cross-threaded, over‑stretched, or the splines spin in the hub, replace the stud—don’t try to “chase” badly damaged threads.
• Press studs out/in with proper support behind the hub, avoid hammering that can stress wheel bearings or ABS tone rings.
• Match replacements: M12×1.25 thread, correct knurl diameter for the hub, and 60° tapered-seat nuts suitable for the wheel type.
• In coastal NZ and Aussie conditions, wash off salt and road grime, light surface corrosion can escalate if ignored.

When replacing, it’s smart to renew any dodgy nuts at the same time, especially if the cone seats are scarred or the hex is rounded. If using wheel spacers or aftermarket wheels, check that the nut seat style and shank length suit the wheel, and always stick to the correct torque. Done right, the Outback’s wheelstudsnuts will deliver years of hassle-free, safe motoring.

Popular questions about 2013 Subaru Outback wheelstudsnuts

What’s the correct wheel nut torque for a 2013 Subaru Outback?

Subaru specifies about 120 N·m on clean, dry threads for the 2013 Outback. Use a torque wrench and tighten in a star pattern, then re-check after 50–100 km. Avoid anti-seize, as it alters clamping force for a given torque.

What size are the wheel studs and nuts on this model?

The studs are M12×1.25 thread and the nuts use a 60° tapered seat, typically with a 19 mm hex. The hub pattern is 5×100. Always match OEM spec when replacing to ensure proper seating and safe clamping.

How do you replace a broken wheel stud on a 2013 Outback?

Remove the wheel and brake components as needed, press the damaged stud out of the hub, and pull the new stud in square using a suitable spacer and nut while supporting the hub. Avoid hammering, and torque the wheel nuts correctly on reassembly.
