Parts for your 2014 Subaru Outback-Wheel studs nuts

2014 Subaru Outback wheel studs and nuts

Technical sources confirm the 2014 Subaru Outback (BR/BM series) uses wheel studs and nuts, not wheel bolts. The Subaru Service Manual (BR/BM Chassis, Suspension – Wheel and Tyre) details hub-mounted studs with conical-seat nuts, the 2014 Owner’s Manual specifies a wheel nut tightening torque of 120 N·m (about 89 ft‑lb), and Subaru’s FAST parts catalogue lists M12 × 1.25 wheel studs (e.g., 28171AJ000) for this model. With five studs per hub and a 5×100 PCD, wheel studs and nuts are very much relevant to this vehicle.

On the 2014 Outback, the wheel studs are press-fitted into the hub flange and the nuts clamp the wheel securely to the hub. It’s a robust, serviceable setup that makes tyre rotations, brake work, and roadside wheel changes straightforward. Keeping these fasteners in good nick is critical for safety and to prevent vibration or warped rotors from uneven clamping.

Good practice for servicing this Outback’s wheel studs and nuts includes:

• Tightening in a star pattern in two to three passes to the specified 120 N·m. A torque wrench beats an impact gun for final nip-up every time.
• Keeping threads clean and dry—no oil or anti-seize on stud or nut threads, as Subaru’s procedure assumes dry torque.
• Inspecting for damage: look for stretched or rusty threads, nicks from cross-threading, or studs that spin in the hub. Any of these call for replacement.
• Checking nut seat style: the OE wheels use a 60° conical seat. Mismatched seats (ball/mag) can loosen or damage wheels.
• Re-torquing after 50–100 km following wheel removal, new tyres, or brake work.

If a stud is stripped or snapped, it’s pressed out from the rear of the hub and a new stud is drawn in squarely using the correct installer or a suitable tool and spacer. Avoid stacking random washers or belting studs in with a hammer while the hub’s on the car—this can load wheel bearings or deform the flange. Replace damaged nuts as a set if their seats or hexes are chewed out, they’re inexpensive insurance.

For owners running aftermarket wheels, stick with 5×100 PCD, 56.1 mm centre bore, M12 × 1.25 thread, and conical-seat nuts to keep things sweet. A quick visual and torque check at each service keeps the Outback tracking straight and drama-free.

Popular questions about 2014 Subaru Outback wheel studs and nuts

What’s the correct wheel nut torque for a 2014 Outback?
Subaru specifies 120 N·m (about 89 ft‑lb) on dry threads. Tighten in a star pattern, then re-check after 50–100 km of driving following any wheel-off work. This helps settle the wheel and prevents brake judder from uneven clamping.

How can someone tell if a wheel stud or nut needs replacing?
Signs include rough or stretched threads, cross-threading, a stud that spins in the hub, or nuts that won’t reach torque without binding. Any visible cracking, heavy rust pitting, or a rounded hex on the nut also means it’s time to bin it and fit new parts.

Are aftermarket nuts okay with new wheels?
Yes, provided they match M12 × 1.25 thread and a 60° conical seat, and the wheels suit 5×100 PCD with a 56.1 mm centre bore. Avoid ball-seat or mag-seat nuts unless the wheel specifically requires them, mismatched hardware can loosen and damage the wheel.
