Parts for your 2009 Subaru Exiga-Wheel studs nuts

2009 Subaru Exiga wheel studs and nuts

Yes, wheel studs and nuts are absolutely relevant to the 2009 Subaru Exiga. Subaru’s technical references confirm it: the Exiga (YA series, 2008–2014) uses pressed-in wheel studs with separate conical-seat wheel nuts on 5-stud hubs. This is stated in the Subaru Exiga (YA) Factory Service Manual under Wheels & Tyres and shown in the Subaru FAST electronic parts catalogue for YA5/YA9 variants (2009 build). Typical OE spec is M12×1.25 thread with a 60° taper-seat nut, and the specified wheel nut torque is 120 N·m.

On this model, the studs are splined and pressed into the hub or axle flange. The nuts clamp the wheel to the hub, creating the friction that actually holds the wheel in place. That setup makes wheel changes quicker, gives consistent clamping, and helps protect hub threads (because the stud can be replaced if damaged, rather than the hub).

As part of routine servicing or after tyre work, it’s smart to check the wheel nuts. Torque them to 120 N·m using a proper torque wrench and a star pattern, and re-check after 50–100 km of driving. Keep the threads clean and dry, Subaru’s torque spec is for dry threads, so avoid lubricants and anti-seize unless a procedure specifically calls for it. Make sure the nut seat style matches the wheel (the Exiga’s OE wheels use a 60° taper seat). If you’ve fitted aftermarket wheels, confirm nut style and length are compatible to maintain proper engagement.

Studs or nuts should be replaced if there’s corrosion, galling, stretched threads, or if a nut won’t hold torque. A cross-threaded or over-tightened nut can deform a stud, leading to loosening or brake vibration. During replacement, press the old stud out and draw the new stud in squarely with a suitable installer or a sacrificial nut and thick washer, ensuring the stud head seats fully on the rear of the flange. Always inspect the mating surfaces and replace any damaged nuts, mixing seat styles is a common cause of clamping loss.

• Torque: 120 N·m (dry), tighten in a star pattern
• Thread: M12×1.25, 5 studs per wheel (5×100 PCD hubs)
• Recheck torque after 50–100 km post wheel/tyre work

Popular questions about 2009 Subaru Exiga wheel studs and nuts

What’s the correct torque for the wheel nuts?
The 2009 Subaru Exiga’s wheel nuts should be tightened to 120 N·m on clean, dry threads. Use a star pattern to seat the wheel evenly, then re-check torque after 50–100 km of driving to make sure everything has settled correctly.

What thread size and type are the Exiga’s wheel studs?
They’re M12×1.25 threaded studs with a 60° taper-seat nut, five per wheel. The Exiga runs 5×100 PCD hubs, so stick with nuts designed for Subaru/Japanese taper-seat wheels unless your aftermarket rims specify a different nut style.

Should anti-seize be used on the wheel studs?
Not recommended. Subaru’s torque spec assumes dry threads. Lubricants or anti-seize change friction and can lead to over-tightening. If a specific repair instruction calls for a compound, follow that guidance and adjust torque as directed, otherwise install dry.
