Parts for your 2011 Subaru Forester-Wheel studs nuts

2011 Subaru Forester wheel studs and nuts

Based on the 2011 Subaru Forester Owner’s Manual (Tyres and Wheels), the Subaru SH-chassis Service Manual, and Subaru’s electronic parts catalogue for MY2011 Forester, this model is built with five wheel studs on each hub and matching lug nuts. So wheel-studs-nuts are absolutely relevant and used on the 2011 Subaru Forester.

On this Forester, the studs are press-in fasteners on the hub, and the lug nuts provide the clamping force that keeps the wheel tight and centred. The OEM setup is a 5x100 bolt pattern with M12 x 1.25 threads, using tapered-seat nuts that locate the wheel securely. Correct torque is critical, Subaru specifies 120 N·m for the wheel nuts on this generation Forester.

As part of routine servicing, wheel studs and nuts deserve a quick check any time the wheels come off—tyre rotations, brake work, puncture repairs, or seasonal wheel swaps. After a wheel has been refitted, it’s good practice to re-torque the nuts to 120 N·m after 50–100 kilometres. Always tighten in a star pattern to seat the wheel evenly, and only torque when the car is back on the ground.

Studs or nuts should be replaced if threads are crossed, stretched, rusty to the point of pitting, or if a nut won’t hold torque. A spinning stud in the hub, a missing nut, or a broken stud is an immediate fix—don’t drive on it. Replace damaged studs promptly to protect the hub and brake rotor hat.

When installing, keep threads clean and dry—no oil, copper paste, or anti-seize on Subaru wheel studs, as it can overstate clamping force. Match the nut’s seat type to the wheel (the OEM Forester wheels use a 60° taper). If switching to aftermarket wheels, confirm seat style and nut length. Press-in studs are knocked out and drawn in from the rear of the hub, many techs remove the hub or swing the knuckle clear to avoid damaging the backing plate or bearings. Use a torque wrench, not a rattle gun, for final tightening.

• Check torque at every tyre rotation (around 10,000 km).
• Inspect studs/nuts during brake services for corrosion and thread wear.
• Replace nuts showing rounded hexes or damaged seats, replace studs that won’t hold proper torque.

Popular question: What’s the correct wheel nut torque for a 2011 Subaru Forester?

The factory torque spec is 120 N·m. Tighten in a star pattern on a clean, dry thread, then re-check after 50–100 kilometres of driving. Using a torque wrench helps avoid warped rotors and stretched studs.

Popular question: Can a single broken wheel stud be replaced, or should they all be done?

It’s fine to replace a single damaged stud if the others are healthy. If multiple studs are corroded or stretched, it’s sensible to replace them as a set on that hub. Always fit a new nut to any new stud.

Popular question: How do I know if my wheel studs or nuts need replacing?

Warning signs include nuts that won’t torque smoothly, threads that feel gritty or bind, visible rust pitting, a nut that keeps coming loose, or any stud that spins or sits short after tightening. If in doubt, replace—these parts are inexpensive insurance for safe wheels.
