Parts for your 2004 Subaru Impreza-Wheel studs nuts

2004 Subaru Impreza wheelstudsnuts

Yes, the 2004 Subaru Impreza is fitted with wheel studs and nuts (not wheel bolts). This is documented in Subaru’s 2004 Impreza Owner’s Manual (wheel nut torque specification), the Subaru Workshop/Service Manual available via Subaru Technical Information System (STIS), and the Subaru parts catalogue, which lists M12 x 1.25 wheel studs and corresponding tapered-seat wheel nuts for both front and rear hubs.

For the 2004 Subaru Impreza, wheelstudsnuts do the heavy lifting of clamping the wheels securely to the hubs. The studs are pressed into the hub and the nuts draw the wheel up tight against the hub face. It’s a simple, reliable setup that makes wheel changes quick and tidy at home or at the track. Factory spec calls for tapered (60°) nuts on M12 x 1.25 studs, tightened to 120 N·m (about 88.5 ft‑lb). Subaru’s guidance is to keep threads clean and dry—no oil, no anti-seize on the threads or seating faces—so the torque is accurate and consistent.

As part of regular servicing, it’s smart to give the wheelstudsnuts a once-over. Look for rounded nuts, damaged tapers, or stretched/cross‑threaded studs. A rattle gun used on “stun” can over-torque and fatigue the hardware, so a torque wrench and a neat star pattern are the go. After any wheel-off work, a re-torque after 50–100 km helps settle things in.

If a stud is bent, stripped, or snapped, replacing it is straightforward with basic tools:

• Safely support the car, remove the wheel, and take off the brake caliper and rotor for access.
• Knock the damaged stud out from the rear of the hub, aligning a gap so it clears the backing plate.
• Seat the new stud from behind, draw it fully home using a sacrificial nut and washers, or press it in with a suitable tool.
• Refit the rotor and caliper, mount the wheel, then torque the nuts to 120 N·m in a star pattern on the ground.

Handy maintenance tips owners like on a 2004subaruimpreza wheelstudsnuts setup:

1. Use correct nuts with clean, matching tapers, avoid universal mag nuts unless specified for the wheel.
2. If using aftermarket wheels or spacers, confirm stud length and nut engagement—aim for at least 8–9 full turns on M12 x 1.25.
3. Replace sets in pairs or full sets if wear is uneven, and keep a couple of spare studs and nuts in the boot for road trips or track days.

Treated right, the Impreza’s studs and nuts last ages, keep tyres centred, and make brake and wheel work a breeze.

What is the correct wheel nut torque for a 2004 Subaru Impreza?

The factory specification is 120 N·m (about 88.5 ft‑lb) on clean, dry threads and seating faces. Tighten in a criss-cross (star) pattern and recheck after 50–100 km of driving to confirm clamp load.

How can someone tell a wheel stud on a 2004 Impreza needs replacing?

Signs include visible bending, flattened or rolled threads, a nut that won’t start by hand, or a stud that spins in the hub. Any snapped stud or damaged taper surface on the nut also calls for replacement to restore proper clamping.

What thread size are the wheel nuts on the 2004 Subaru Impreza, and can anti-seize be used?

The studs are M12 x 1.25 with a 60° tapered-seat nut. Subaru service literature specifies clean and dry assembly—avoid lubricants or anti-seize on the threads or seating faces to maintain accurate torque.
