Parts for your 2008 Subaru Forester-Wheel studs nuts

2008 Subaru Forester wheel studs and nuts

Wheel studs and nuts are absolutely used on the 2008 Subaru Forester. Subaru’s factory service manual and the owner’s manual specify tightening torque for wheel nuts, and the Subaru parts catalogue lists press-in wheel studs (M12 x 1.25) with matching tapered-seat nuts for this model. That confirms the Forester runs hub-mounted studs with separate nuts, not wheel bolts.

On a 2008 Forester, the wheel studs and nuts clamp the wheel firmly to the hub, providing the clamping force that keeps the wheel centred and secure under braking, cornering, and off‑road bumps. Subaru uses press-in studs on the hub and 60° tapered-seat nuts to self-centre the wheel as they’re tightened. It’s a simple, reliable setup that also makes roadside tyre changes a bit easier, since the wheel hangs on the studs while the nuts are started by hand.

For servicing, the key is correct torque and clean mating faces. Subaru specifies tightening the wheel nuts evenly in a criss-cross pattern with a torque wrench, typically around 120 N·m (about 88.5 lb‑ft) for this generation. Always start nuts by hand to avoid cross‑threading, keep the hub face and wheel seating areas free of rust and debris, and do not lubricate the threads or the nut seats, as that changes clamp load. After any wheel-off job—tyres, brakes, rotation—it’s smart practice to re-check torque after 50–100 km.

Replacement is straightforward when needed. Swap studs if the threads are damaged, stretched, or corroded, or if a nut has seized. A common cause of failure is over-tightening with a rattle gun. To replace a stud, the brake caliper and rotor are usually removed for access, the old stud is driven out, and the new one is drawn fully home from the front using a sacrificial nut and flat washers, then verified to seat squarely. Replace any deformed nuts and always match the seat type to the wheel—most OEM Forester wheels use a 60° tapered seat. Stick with the correct thread pitch (M12 x 1.25) and use a torque wrench for final tightening. Done right, the studs and nuts will deliver years of quiet, drama-free motoring on Aussie and Kiwi roads.

• Torque wheel nuts to 120 N·m in a star pattern
• Re-torque after 50–100 km post-service
• Replace damaged studs/nuts, do not lubricate threads or seats
• Verify 60° tapered-seat nuts and M12 x 1.25 threads

Popular questions

What’s the correct wheel nut torque for a 2008 Subaru Forester?

The commonly specified torque is 120 N·m (about 88.5 lb‑ft). Tighten in a criss-cross pattern on a clean, dry hub and wheel seat, then re-check after 50–100 km. Avoid using a rattle gun for final torque—finish with a calibrated torque wrench.

What thread size and seat type does it use?

Wheel studs are typically M12 x 1.25 with right-hand threads, and the OEM nuts are 60° tapered (conical) seat to match factory wheels. If running aftermarket rims, always confirm the seat type and nut style recommended by the wheel maker.

How do you replace a broken wheel stud?

Remove the wheel, caliper, and rotor for access, drive the damaged stud out from the rear, then draw the new stud fully into the hub using a stack of flat washers and a spare nut. Ensure it seats flush. Refit the rotor and caliper, refit the wheel, and torque the nuts to 120 N·m. If a stud snapped due to over-tightening, replace the affected nut as well.
