Parts for your 2023 Subaru Impreza-Wheel studs nuts

2023 Subaru Impreza wheel studs and nuts

Based on technical sources including the 2023MY Subaru Impreza Owner’s Manual (Wheels and Tyres), the Subaru Service Manual (Front/Rear Axle – Hub Unit Bearing), and the Subaru genuine parts catalogue, the 2023 Subaru Impreza is fitted with press-in wheel studs and separate wheel nuts (not wheel bolts). These sources also specify a wheel nut torque of around 120 N·m, confirming the vehicle relies on traditional studs-and-nuts hardware.

For the 2023 Subaru Impreza, wheel studs and nuts do the heavy lifting that keeps each wheel securely clamped to the hub. The studs are pressed into the hub and provide sturdy, accurately placed threads, the nuts clamp the wheel to the hub face when torqued correctly. It’s a simple, reliable setup that makes wheel changes quick and helps protect hub threads from damage. On the Impreza, the hardware is typically M12 × 1.25 with a 60° taper-seat nut to match the wheel’s cone seat.

As part of regular servicing—think tyre rotations around every 10,000 km or any time a wheel’s been off—it’s smart to check the condition of both studs and nuts. Subaru’s guidance calls for tightening to 120 N·m using a torque wrench. A star (criss-cross) pattern helps the wheel seat evenly, and a short re-torque after 50–100 kilometres of driving settles everything in. Avoid oil or anti-seize on the threads or the seating faces, clean and dry is the go for accurate clamp load.

• Inspection tips:
  • Look for stretched or damaged threads, rust pitting, and any signs of cross-threading.
  • Check nut seats for galling or deformation—replace any suspect nuts, ideally as a set on that wheel.
  • Ensure the wheel’s taper seats are clean and free of paint build-up or grit.
• Replacement pointers:
  • Studs press out from the back of the hub and new ones press in square—avoid hammering to protect the bearing.
  • Use quality M12 × 1.25 studs/nuts that match the wheel’s 60° taper seat, mixing seat types can loosen wheels.
  • If a nut has been over-tightened with a rattle gun, replace it and re-check the stud.

Daily driving around Aussie and Kiwi coastlines can mean extra exposure to salt air, so keeping the hub face clean and the wheel snugly torqued helps prevent fretting corrosion. Done right, the Impreza’s studs and nuts will deliver quiet, drama-free kilometres.

Popular questions about 2023 Subaru Impreza wheel studs and nuts

What’s the correct wheel nut torque on a 2023 Subaru Impreza?

The factory torque is about 120 N·m (roughly 88.5 ft·lbf). Tighten in a star pattern with a torque wrench on clean, dry threads and seats. If a rattle gun is used to remove wheels, always finish by hand-torquing to spec.

How soon should wheel nuts be re-torqued after a tyre rotation or wheel change?

After any wheel-off job, it’s good practice to re-torque after 50–100 km of driving. This allows the wheel, nut, and stud seating to settle so the clamping force remains consistent.

Can a damaged wheel stud be replaced individually on a 2023 Impreza?

Yes. A single damaged stud can be pressed out and a new stud pressed in without replacing the entire hub, provided the hub and bearing aren’t harmed. Use the correct M12 × 1.25 stud and match the wheel’s taper-seat nuts, then torque to 120 N·m.
