Parts for your 2022 Subaru Impreza-Wheel studs nuts

2022 Subaru Impreza wheel studs and nuts — purpose, care, and service tips

Yes, the 2022 Subaru Impreza uses separate wheel studs and lug nuts (not wheel bolts). This is confirmed by Subaru’s technical literature, including the MY2022 Impreza Owner’s Manual (Wheels and Tyres section), the Subaru Service Manual via STIS (Brake/Hub and Wheel sections), and Subaru Genuine Parts catalogues noting M12 x 1.25 studs with conical-seat nuts. Those sources also specify the factory wheel nut torque at 120 N·m (about 89 ft‑lb), applied in a criss-cross pattern.

On the Impreza, the wheel studs and nuts provide the clamping force that holds the wheel and brake rotor securely against the hub. The conical-seat nuts help centre the wheel on the hub face and maintain even clamp load so the tyre runs true and the rotor stays stable under braking. Properly torqued studs and nuts keep the friction interface tight, which is what actually carries the vehicle’s load and resists cornering and braking forces.

As part of routine servicing and any tyre or brake work, it pays to give the studs and nuts a quick once-over. Subaru’s guidance is to install them clean and dry—no oil, grease, anti-seize, or threadlocker on the threads or seats—and torque to 120 N·m with a calibrated torque wrench after snugging by hand. If an impact gun is used to remove or seat nuts, always finish with hand torque.

• Check torque after 50–100 km following a wheel refit or rotation.
• Inspect studs and nuts at each tyre rotation (typically every 10,000–15,000 km).
• Replace any stud with damaged or stretched threads, corrosion pitting, or if a nut won’t hold torque.
• Use only the correct thread (M12 x 1.25) and 60° conical-seat nuts, mismatched hardware can cause vibration or loss of clamping force.

Stud replacement on the Impreza is a straightforward press-in job but does require proper support of the hub and correct installation torque when drawing the new stud into place. If a nut has been over-torqued, cross-threaded, or its seat is galled, replace it as well. Keeping to these basics means the wheels come on and off smoothly, brake rotors stay true, and the Impreza tracks straight without annoying wheel shake.

FAQs

Do 2022 Subaru Imprezas use wheel studs and nuts or wheel bolts?
They use five press-in wheel studs per hub with separate conical-seat lug nuts. This design is noted in Subaru’s Owner’s Manual and Service Manual for the model year.

What’s the correct wheel nut torque for a 2022 Impreza?
Subaru specifies 120 N·m (about 89 ft‑lb). Tighten in a criss-cross pattern on a clean, dry interface and recheck after 50–100 km if the wheel has been off.

When should wheel studs or nuts be replaced?
Replace any time threads are damaged, a nut won’t hold torque, there’s visible rust pitting, or after severe over-torque or cross-threading. It’s smart to inspect them at each tyre rotation or brake service.
