Parts for your 2023 Subaru Impreza-Wheel studs nuts

2023 Subaru Impreza wheel studs and nuts

Wheel studs and nuts are absolutely relevant to the 2023 Subaru Impreza. According to the 2023 Subaru Impreza Owner’s Manual (Wheels and Tyres section), the car uses wheel nuts with a specified tightening torque of 120 N·m (88.5 lbf·ft). The Subaru Service Manual for the model generation shows a hub with pressed-in studs that accept separate nuts, and Subaru genuine parts catalogues list M12 × 1.25 wheel studs and matching conical-seat wheel nuts for this vehicle. That confirms the Impreza does not use wheel bolts.

On this Impreza, the five pressed-in studs on each hub provide the threaded anchors, and the wheel nuts clamp the wheel and brake rotor snugly to the hub face. It’s a simple, robust setup that makes wheel changes quick and helps with accurate centring. Because they carry all the clamping load, healthy studs and clean, correct-spec nuts are key to keeping the wheel secure, avoiding brake judder, and preventing vibration on the motorway.

As part of routine servicing or any tyre rotation, a few basics keep the hardware in top nick:

• Always torque wheel nuts to 120 N·m using a calibrated torque wrench, tighten in a star pattern and recheck after 50–100 km.
• Keep threads clean and dry, Subaru guidance expects dry torque—avoid oil or anti‑seize on studs/nuts unless a specific service bulletin says otherwise.
• Inspect for damage: stretched or cross‑threaded studs, cracked or deformed nuts, or chewed cone seats should be replaced.
• If a nut runs tight by hand, stop—clean the threads or replace the affected part to avoid galling.
• Use the correct conical-seat nuts, mismatched seats can loosen and damage the wheel.
• Avoid rattle guns for final tightening, use them only for removal or snugging at low setting, then finish with a torque wrench.

Replacement is straightforward: a damaged stud is pressed out of the hub and a new OEM-spec stud is pulled in squarely from behind, always replace the matching nut. If multiple studs are suspect—after an over‑torque incident, wheel-off event, or severe kerb strike—replace them as a set on that hub. During each service or at tyre rotations (typically every 10,000–15,000 km), ask for a quick check of stud condition and nut torque. Doing so helps protect the wheel, brakes, and bearings, and keeps the Impreza feeling tight and confidence-inspiring on Aussie and Kiwi roads.

Popular questions about 2023 Subaru Impreza wheel studs and nuts

What’s the correct wheel nut torque for a 2023 Subaru Impreza?
Subaru specifies 120 N·m (88.5 lbf·ft). Tighten in a star pattern and recheck after 50–100 km of driving, especially after a tyre rotation or puncture repair.

Can anti-seize be used on Impreza wheel studs?
Best practice is clean and dry threads. Lubricants or anti‑seize change friction and can lead to over‑torque and stretched studs. Only use a lubricant if a Subaru service bulletin explicitly allows it.

When should wheel studs or nuts be replaced?
Replace any stud with damaged or stretched threads, or after severe over‑torque. Swap out nuts with rounded hexes, cracked cones, or distorted seats. It’s wise to inspect at every tyre rotation.
