Parts for your 2016 Subaru Exiga-Wheel studs nuts

2016 Subaru Exiga wheel studs and nuts: purpose, care, and when to replace

Wheel studs and nuts are absolutely used on the 2016 Subaru Exiga. Subaru specifies hub-mounted studs with separate wheel nuts (not bolt-in wheel fasteners) across the YA-series Exiga. This is supported by the Subaru Exiga Owner’s Manual guidance to tighten wheel nuts to spec and the YA-series Factory Service Manual procedures covering stud replacement and nut inspection.

On the Exiga, the wheel studs are the threaded pins pressed into the hub. The wheel nuts clamp the wheel to the hub and brake rotor hat, providing the critical clamping force that keeps the wheel seated and running true. Done right, that clamping load handles every bump, corner, and braking event without the wheel fretting or loosening.

For day‑to‑day care, torque matters most. Subaru service data calls for tightening the wheel nuts evenly in a criss‑cross pattern to 120 N·m using a torque wrench, not a rattle gun. The nuts and stud threads should be clean and dry—no oil, grease, anti‑seize, or thread locker—so the torque translates into predictable clamping. After any wheel-off job (tyres, brakes, suspension), it’s smart practice to recheck torque after 50–100 km of driving.

Studs and nuts don’t have a fixed replacement interval, but they do have a hard life. They should be inspected at every tyre rotation or service. Replace any nut that’s rounded, rust-pitted, or has a damaged seat. Replace any stud that’s bent, cross‑threaded, stretched, or has damaged threads, or if it spins in the hub. Most Exiga variants use M12 × 1.25 studs with 60° taper‑seat nuts—match the thread pitch and seat type to the wheel design and confirm against Subaru service info or the wheel/vehicle label.

When fitting wheels, seat the wheel fully on the hub, start nuts by hand, snug them in stages, then final‑torque to spec. Avoid impact “zapping” to final torque. If a stud has failed, the service manual procedure involves pressing out the old stud and drawing in a new, OE‑grade stud squarely into the hub flange. It’s good practice to replace any suspect nuts as a set on the same axle and to check brake rotor/hub mating faces for rust or debris that can halve clamping and cause a wobble.

• Torque: 120 N·m (use a calibrated torque wrench)
• Pattern: Star/criss‑cross
• Threads: Clean and dry, correct pitch (M12 × 1.25 typical)

Popular questions about 2016 Subaru Exiga wheel studs and nuts

What is the correct wheel nut torque for a 2016 Subaru Exiga?

The commonly specified torque is 120 N·m for the Exiga’s wheel nuts, applied in a criss‑cross pattern on a clean, dry thread and seat.

After wheel service or rotation, a torque check after 50–100 km helps catch any settling and keeps the wheel clamped properly.

How often should wheel studs and nuts be replaced?

There’s no time‑based interval. Replace on condition: damaged threads, corrosion, rounded nut flats, distorted seats, or any stud that’s bent or has spun in the hub.

Inspect at every tyre rotation or brake service, and always match the correct M12 × 1.25 thread and seat style when fitting replacements.
