Parts for your 2022 Subaru Outback-Wheel studs nuts

2022 Subaru Outback wheelstudsnuts — what they do and how to look after them

Based on the 2022 Subaru Outback Owner’s Manual and Subaru workshop/service literature, this model uses traditional wheel studs with separate lug nuts — wheelstudsnuts — rather than wheel bolts. Those technical sources specify a wheel nut tightening torque of about 120 N·m (roughly 88–90 lb·ft) on clean, dry threads, and show pressed-in studs on the hub. So wheelstudsnuts are absolutely relevant to the 2022 Subaru Outback.

On the Outback, wheelstudsnuts clamp the wheel to the hub face, creating the right clamping force so the wheel can handle cornering, braking, and bumps without shifting. The studs are pressed into the hub, and the nuts (typically 60° conical-seat, M12 x 1.25 thread, 19 mm hex) draw the wheel up evenly as they’re torqued. Done right, they keep the wheel centred and secure without crushing the alloy.

Good servicing habits go a long way. Always tighten in a star pattern, using a torque wrench to the factory spec (about 120 N·m unless the owner’s manual for your trim says otherwise). After any tyre rotation, puncture repair, or wheel swap, it’s smart practice to re-check the torque after 50–100 kilometres. That quick recheck helps catch any settling of the wheel or paint on new alloys that can relax the clamp load.

Keep threads clean and dry. Subaru’s specs are for dry torque, so avoid lubricants or anti-seize on studs or nuts — they can overstate clamp force and risk stretching studs. If you’re battling corrosion, clean with a nylon brush and replace badly pitted hardware instead of trying to “save” it with lube.

Know when to replace wheelstudsnuts. Watch for cross-threading, rounded hexes, damaged cone seats, or a nut that feels “soft” before reaching torque — all signs to bin it. A stud that’s stretched, rusty to the point of flaking, spinning in the hub, or snapped needs replacement. Subaru studs are pressed into the hub, a workshop can usually swap a single damaged stud without replacing the whole hub, but multiple failures may justify a hub assembly.

Match the seat type to the wheel. OEM alloys use a 60° taper, mixing mag-seat or ball-seat nuts with taper-seat wheels leads to poor contact and loosening. Impact guns are fine for removal, but finish tightening by hand with a torque wrench. Simple, tidy habits keep the Outback’s wheels safe and squeak-free.

• Torque: about 120 N·m on clean, dry threads
• Thread: M12 x 1.25, 60° conical seat (OE wheels)
• Service tip: star-pattern tightening, recheck after 50–100 km
• Replace if: threads damaged, seats gouged, studs stretched or corroded

Popular questions about 2022 Subaru Outback wheelstudsnuts

What’s the correct wheel nut torque for a 2022 Subaru Outback?

For most 2022 Outback trims, the spec is about 120 N·m on clean, dry threads. Use a torque wrench and a star pattern, then recheck after 50–100 kilometres following any wheel or tyre work. If your model has specialty wheels or accessories, confirm the exact spec in the owner’s manual.

What size and seat type are the wheelstudsnuts on a 2022 Outback?

They’re typically M12 x 1.25 studs with 60° conical-seat nuts and a 19 mm hex. Always match the seat type to the wheel. Aftermarket rims may call for different nuts, if in doubt, ask the wheel supplier or a Subaru-savvy tyre shop.

Should anti-seize be used on Subaru wheelstudsnuts?

No. The factory torque values assume dry threads. Lubricants or anti-seize can cause over-tightening and stretch studs. If corrosion is a worry, clean the threads and replace any suspect hardware rather than lubricating it.
