Parts for your 2012 Subaru Impreza-Wheel studs nuts

2012 Subaru Impreza wheelstudsnuts — fitment, purpose, and service tips

Based on the 2012 Subaru Impreza factory documentation (Service Manual, Wheels and Tyres section) and the Owner’s Manual torque guidance, this model uses press-in wheel studs with separate lug nuts (wheelstudsnuts). The platform (GP/GJ) runs a 5x100 PCD hub, M12 x 1.25 thread pitch studs, and a recommended wheel nut torque of 120 N·m (about 88.5 ft‑lb). That combination confirms wheelstudsnuts are fitted and are the correct fastener style for clamping the wheel to the hub on a 2012 Subaru Impreza.

On this Impreza, wheelstudsnuts do the heavy lifting by providing consistent clamping force between the wheel and hub face. Properly torqued nuts keep the brake rotor located and the wheel seated true, helping avoid vibrations, uneven tyre wear, and braking shimmy. Subaru uses studs rather than bolts so the wheel can be hung on the studs for easy alignment—handy when swapping to the spare on a wet Kiwi roadside or after a weekend tyre rotation in the Aussie sun.

For servicing of your 2012subaruimpreza wheelstudsnuts, a few simple habits go a long way. Always tighten with a torque wrench to 120 N·m on clean, dry threads and seats—no oil, grease, or anti-seize, as lubrication can over-stress the studs. Use a star pattern in two or three passes to settle the wheel evenly. After any wheel-off job (tyres, brakes, suspension), re-check torque after 50–100 kilometres. If an impact gun is used for removal, finish tightening by hand with the torque wrench to avoid stretching studs or rounding nuts.

Match hardware to the wheel: the 2012 Impreza typically uses 60‑degree tapered-seat nuts for OEM wheels. Using the wrong seat style or mixing open and closed nuts can damage the wheel or work loose. When studs show damaged threads, corrosion pitting, or have been over-torqued, replace them—these are press-in studs from the rear of the hub, and some hubs require removal for proper pressing. Replace any nut with a chewed hex, cracked cap, or worn seat.

• Warning signs: recurring wheel shake after torque, nuts that won’t hold torque, visible cross-threading, or a clicking/clunking noise on turns.
• Service rhythm: check condition and torque at every tyre rotation (about every 10,000 km), after pothole hits, and whenever wheels are removed.

Following the factory specs—from the Subaru Owner’s Manual torque figure and the Service Manual fitment notes—keeps the wheelstudsnuts doing their job without drama, mile after mile.

Popular question: What is the correct wheel nut torque for a 2012 Subaru Impreza?

The factory spec is 120 N·m (about 88.5 ft‑lb) on clean, dry threads and seats. Tighten in a star pattern and re-check after 50–100 km whenever wheels have been off. Avoid lubricants on the threads, as they change the clamping force.

Popular question: What thread size and seat type are the 2012 Subaru Impreza wheelstudsnuts?

The studs are M12 x 1.25, right‑hand thread. OEM nuts are typically 60‑degree tapered seat to match Subaru wheels. Always match the seat style to the wheel to maintain proper clamping and prevent damage.

Popular question: Can a single damaged wheel stud be replaced on a 2012 Impreza?

Yes. A damaged stud should be pressed out and a new one pressed in from the rear of the hub. Depending on the corner, the hub may need removal for safe access. Replace the affected nut as well and torque the new assembly to 120 N·m.
