Parts for your 2014 Subaru Exiga-Wheel studs nuts

2014 Subaru Exiga wheel studs and nuts

Based on Subaru’s technical literature and parts data for the YA‑series Exiga (2014), this model uses wheel studs and nuts rather than wheel bolts. The Subaru Service Manual and Subaru parts catalogues list press‑in M12 × 1.25 studs with conical‑seat wheel nuts, and the Owner’s Manual refers to “wheel nuts” and specifies tightening torque. That aligns with common Japanese industry practice (JIS) where hubs carry studs and the wheel is secured by nuts.

On the 2014 Subaru Exiga, the wheel studs and nuts do a deceptively big job. They provide the clamping force that sandwiches the wheel and brake disc firmly against the hub face. The tapered seat of each nut centres the wheel on the hub and helps maintain even load under cornering, braking, and those long Kiwi and Aussie highway runs. When correctly torqued, they keep the wheel true, protect the hub and bearings from fretting, and ensure even brake rotor contact.

For servicing, the essentials are straightforward: start the nuts by hand, seat the wheel flush to a clean hub face, and tighten in a star pattern. Subaru service data for the Exiga specifies approximately 120 N·m on clean, dry threads and seats—no oil or grease on the threads or the taper, as lubrication can over‑clamp and distort torque readings. After any wheel refit, recheck torque after 50–100 kilometres.

1. Inspect at every service or tyre rotation: look for stretched, rusty, cross‑threaded, or damaged threads, and check for deformed nut seats.
2. If a stud spins in the hub, or a nut won’t torque up smoothly, replace the affected parts immediately.
3. Use a torque wrench to finish the job, an impact gun is fine for removal, but final tightening should be by hand to spec.
4. Match parts correctly: Exiga studs are M12 × 1.25 with 60° conical nuts, avoid mismatched seats or thread pitches.

Replacing a damaged stud on the Exiga involves pressing the old stud out of the hub flange and drawing or pressing a new stud in squarely. The brake caliper and rotor usually need to come off for access. If the knurl in the hub is worn, the hub may need replacing to ensure proper stud grip. In coastal Aussie or NZ conditions, light surface corrosion is common—wire‑brush the hub face (not the stud threads) and replace any nut that shows thread galling or a chewed seat. Quality OE or reputable aftermarket studs and nuts are recommended, and any time a wheel has been off, it’s worth a quick torque check at the next fuel stop.

Popular questions

What is the correct wheel nut torque for a 2014 Subaru Exiga?

The commonly published Subaru spec for the 2014 Exiga is 120 N·m on clean, dry threads and seats. Tighten in a star pattern and re‑check after 50–100 kilometres. Avoid lubricants on the threads or the tapered seat unless a Subaru bulletin specifies otherwise.

Are Exiga wheel nuts the same as other Subaru models?

Many Subarus share M12 × 1.25 studs and 60° conical nuts, but nut length, seat style, and flange design can vary. For alloy wheels, match the original seat type and length, mixing seat styles can lead to poor clamping and warped rotors.

How is a broken wheel stud replaced on a 2014 Exiga?

The wheel, caliper, and rotor are removed, the damaged stud is pressed out, and a new stud is pressed or drawn in square to the hub. Refit the rotor and caliper, then torque the nuts to 120 N·m. If unsure, a professional mechanic can handle it quickly and safely.
