Parts for your 2014 Subaru Forester-Wheel studs nuts

2014 Subaru Forester wheel studs and nuts: purpose, care and when to replace

Technical Subaru sources (2014 Forester Owner’s Manual, SJ Forester Service Manual – Wheel & Tyre section, and Subaru parts catalogue) confirm the 2014 Subaru Forester uses press-in wheel studs with separate wheel nuts. The hubs are five-stud, with M12×1.25 threads, so wheel studs and nuts are absolutely relevant to this model.

On the 2014 Forester, the wheel studs and nuts do the simple but critical job of clamping the wheel squarely to the hub. Five studs on a 5×100 PCD share the load, and the conical-seat nuts centre the wheel as they’re tightened. Done right, the clamping force keeps the wheel located through corrugations, wet commutes, and long holiday kilometres alike.

For servicing, the big ticket is correct torque. Subaru service information specifies 120 N·m for the wheel nuts. Tighten in a star pattern to seat the wheel evenly, then re-check torque after 50–100 km any time a wheel has been off for tyres, brakes or rotation. Fit the nuts dry—no oil, grease or anti-seize—as lubrication can distort torque readings and over-stress the studs.

Before refitting, clean the hub face and the wheel’s mounting pad so there’s no rust scale or grit that could cause run-out or loosening. If using an impact gun to remove nuts, finish tightening with a torque wrench. Avoid mixed nut styles, the Forester uses a 60° tapered (cone) seat, typically with a 19 mm hex.

Inspection is quick: look for damaged or stretched threads, heavy corrosion, a nicked or gouged cone seat on the nuts, or a stud that spins in the hub (loose spline). Any of those are a replace-now item. A cross-threaded nut or stud should never be “chased” back on, that only weakens the fastener.

Replacement of a stud is straightforward for a pro: the brake calliper and rotor usually come off, the damaged stud is pressed out of the hub flange, and a new OEM-quality stud is pulled in square with a proper installer. Nuts with chewed seats, swollen chrome caps, or deformed threads should be replaced as a set on that wheel. During regular servicing (including 10,000 km tyre rotations), a quick torque check and a visual once-over of studs and nuts helps keep the Forester safe and squeak-free.

• Torque spec: 120 N·m, star pattern, re-check after 50–100 km
• Thread: M12 × 1.25, 5×100 hub pattern, 60° tapered-seat nuts
• Install dry, clean hub and wheel faces, inspect for damage or corrosion

Popular questions about 2014 Subaru Forester wheel studs and nuts

What’s the correct wheel nut torque on a 2014 Subaru Forester?

The specified torque is 120 N·m. Tighten the five nuts in a star pattern, then re-check after 50–100 km whenever a wheel has been off for tyres, brakes or rotation. Always finish with a torque wrench and keep the threads dry.

This helps prevent warped rotors, loose wheels, and stud stretch. If a shop used an impact gun, ask for a torque verification before driving off.

What thread size and seat type does the Forester use?

The 2014 Forester uses M12 × 1.25 studs with 60° tapered (cone-seat) nuts, typically 19 mm hex. The hub pattern is 5×100. Stick with the correct cone-seat style—spherical or mag-seat nuts won’t centre the wheel properly.

Mixing nut styles can lead to vibration, ovalled wheel seats, or wheels that won’t stay tight. If changing wheels, confirm the seat type matches your nuts.

When should wheel studs or nuts be replaced?

Replace any time threads are cross-threaded, stretched, rusty, or the nut’s cone seat is chewed up. A stud that spins in the hub or shows spline damage is done. After a severe over-torque event, it’s smart to renew that wheel’s nuts (and the affected stud).

Use OEM or high-quality aftermarket parts, install studs squarely, and torque the wheel nuts correctly to keep everything snug and safe.
