Parts for your 2017 Subaru Outback-Wheel studs nuts

2017 Subaru Outback wheel studs and nuts

Referencing the 2017 Subaru Outback Owner’s Manual, the Subaru Service Manual (Wheels/Tyres and Suspension sections), and OEM parts catalogues, this model is fitted with wheel studs and separate wheel nuts (not wheel bolts). The hubs use five studs (5×114.3 PCD) with M12×1.25 threads, and the specified wheel nut tightening torque is 120 N·m. So yes—wheel studs and nuts are absolutely relevant to the 2017 Subaru Outback.

On this Outback, the wheel studs and nuts do the heavy lifting of clamping each wheel securely to the hub. When tightened correctly, they keep the brake rotor and wheel seated true, helping the car track straight, brake predictably, and avoid vibration. If they’re over-tightened, under-tightened, cross-threaded, or corroded, the clamping load can be wrong, which risks warped rotors, loose wheels, or even stud failure—none of which anyone wants on a long Kiwi or Aussie road trip.

As part of routine servicing or whenever tyres are rotated or replaced, it’s smart practice to:

• Inspect studs and nuts for damaged threads, rust pitting, or stretching (a shiny “necked-down” section is a red flag).
• Clean the threads with a soft brush, avoid harsh abrasives that remove material.
• Install nuts clean and dry—no oil or grease on threads or seating faces unless a Subaru service bulletin specifically says otherwise.
• Tighten in a star pattern to 120 N·m using a torque wrench, not an impact gun for final torque.
• Recheck torque after 50–100 km following any wheel service.

If a stud is bent, stripped, or seized, it should be replaced—press the old one out and the new one in with proper support to protect the hub and bearing. Wheel nuts with damaged seats, swollen caps, or chewed hexes are also due for replacement. Always match the nut’s seat profile to the wheel design, mixing seat types can lead to poor clamping and vibration.

For owners who tow, venture off-road, or live near the coast, a quicker inspection cycle helps catch early corrosion. Sticking with quality, correct-spec studs (M12×1.25) and nuts, and always using the right torque, keeps this Outback feeling tight, safe, and ready for the next run.

What’s the correct torque for the 2017 Subaru Outback’s wheel nuts?

The factory specification is 120 N·m. Tighten in a star pattern with a calibrated torque wrench, then recheck after 50–100 km if the wheels have been off. This helps avoid rotor distortion and wheel vibration.

What thread size are the 2017 Outback’s wheel studs?

The studs are M12×1.25 on a 5-stud hub (5×114.3 PCD). Always use nuts that match both the thread and the correct seat profile for the wheel being fitted.

Can anti-seize or lubricant be used on Subaru wheel studs?

Subaru workshop guidance is to install wheel nuts clean and dry. Lubricants can alter clamping force at the same torque. Unless a Subaru bulletin says otherwise, keep threads and seats dry and clean, and torque to 120 N·m.
