Parts for your 2015 Subaru Forester-Wheel studs nuts

2015 Subaru Forester wheel studs and nuts

Based on technical references — the Subaru Forester (SJ, MY2015) Owner’s Manual, the Subaru Service Manual for the SJ platform, and the Subaru parts catalogue used by dealers — the 2015 Subaru Forester is built with pressed-in wheel studs and matching wheel nuts (not wheel bolts). That means each hub has fixed studs, and the wheels are secured with nuts tightened to a specified torque.

On this model, the wheel hardware does the hard yakka of clamping the wheel and brake rotor to the hub. Subaru specifies five studs per wheel, using an M12 x 1.25 thread, with taper-seat (60° cone) nuts to match the factory alloys and steels. The typical wheel nut torque for MY2015 Forester is 120 N·m (about 89 ft‑lb), as noted across Subaru manuals and dealer service data. Non‑turbo variants generally use a 5x100 PCD, while XT models use 5x114.3, but both run the same stud-and-nut concept.

As part of routine servicing or any tyre rotation, it’s smart to check the condition of the wheel studs and nuts. They’re not a scheduled replacement item, instead, they’re replaced on condition — if threads are damaged, studs are stretched, or the seat faces are chewed out.

• Torque matters: Always tighten wheel nuts to 120 N·m using a torque wrench. Over-tightening can stretch studs, under-tightening can let the wheel fret and loosen.
• Keep it dry: Subaru torque specs are for clean, dry threads — don’t lubricate studs or nuts, and skip anti-seize here.
• Match the seat and thread: Use 60° taper-seat nuts with M12 x 1.25 thread. The wrong seat or pitch can damage the wheel or studs.
• Re-check after driving: After fitting wheels or rotating tyres, re-torque after 50–100 km.
• Inspect regularly: Look for rust pitting, cross-threading, or any nut that goes on too easily or binds early — all signs of trouble.

If a stud is damaged, a technician will press the old stud out of the hub flange and press a new one in, then refit with a correct-spec nut. If nuts are rounded, swollen, or the taper is scored, replace them as a set for that wheel. It’s a small cost that protects the hub, brakes, and tyres — and keeps road trips across Australia and New Zealand drama-free.

Popular questions about 2015 Subaru Forester wheel studs and nuts

What’s the correct wheel nut torque for a 2015 Subaru Forester?

The recommended torque is 120 N·m (about 89 ft‑lb) on clean, dry threads. Use a torque wrench, tighten in a star pattern, and re-check after 50–100 km of driving.

What thread size and seat type are the wheel nuts on a 2015 Forester?

The factory studs are M12 x 1.25, and the OEM nuts use a 60° taper (cone) seat. Always match both the thread pitch and the seat style to avoid wheel or stud damage.

When should wheel studs be replaced on a 2015 Forester?

There’s no fixed interval. Replace any stud with stripped threads, visible stretching, severe corrosion, or if it won’t hold torque. Replace suspect nuts at the same time to protect the new studs.
