Parts for your 2017 Subaru Impreza-Wheel studs nuts

2017 Subaru Impreza wheel studs and nuts

Based on Subaru’s technical guidance, wheel studs and nuts are indeed fitted to the 2017 Subaru Impreza. The MY17 Impreza Owner’s Manual (AUS/NZ) and the Subaru Service Manual “Wheel and Tyre” section specify five press-in wheel studs per hub secured by wheel nuts, with a typical tightening torque of about 120 N·m. Subaru’s FAST electronic parts catalogue for the 2017 Impreza (GT series) also lists wheel studs and wheel nuts as service parts. That confirms this vehicle uses a stud-and-nut arrangement rather than wheel bolts.

On the 2017 Impreza, the wheel studs and nuts do the heavy lifting of clamping the wheel to the hub. They provide the correct clamping force so the wheel stays centred and secure under braking, cornering and rough Kiwi or Aussie roads. Subaru uses a fine thread (commonly M12 × 1.25) with a 60° tapered seat nut to match the wheel’s cone seat. Keeping threads clean and dry is key—Subaru workshop literature specifies tightening on dry, undamaged threads, not lubricated ones, so the torque figure actually delivers the intended clamping force.

As part of regular servicing or any tyre rotation, it’s smart to inspect and correctly torque the nuts. A calibrated torque wrench at around 120 N·m, tightened in a star pattern, keeps things even. After a wheel’s been off, recheck torque after 50–100 km. If a nut feels “soft” before reaching torque, or if it won’t hold torque, there’s likely thread damage on the nut or stud.

• Check for: stretched or cross‑threaded studs, rounded or cracked nuts, rust pitting on threads, damaged cone seats, or a stud that spins in the hub.
• Replace any suspect parts immediately—don’t mix damaged hardware with good hardware.
• Avoid anti-seize or grease on threads or seats unless a Subaru bulletin specifically says otherwise.

Stud replacement on an Impreza involves pressing the old stud out of the hub flange and pressing a new one in from the rear. That typically means removing the wheel, caliper and rotor, then using a press or suitable tool to seat the new stud squarely. Drawing studs in with a nut and washers can load the bearing—use care, or get a technician to handle it. With fresh, correct-spec wheel nuts and properly torqued studs, the Impreza’s wheels stay safe, true and trouble-free.

Popular questions about 2017 Subaru Impreza wheel studs and nuts

What’s the correct wheel nut torque for a 2017 Impreza?
Subaru workshop data for the MY17 Impreza specifies about 120 N·m. Tighten in a criss-cross pattern on clean, dry threads, then recheck after 50–100 km if the wheel was recently removed.

Can anti-seize be used on the wheel studs?
Not recommended. Subaru documentation calls for dry assembly. Lubricants change the friction and can lead to over‑tightening and potential stud or rotor issues.

What thread size and seat type do the nuts use?
The Impreza typically uses M12 × 1.25 wheel studs with a 60° tapered (conical) seat nut. Always match the seat type to the wheel to ensure proper clamping.
