Parts for your 2014 Subaru Impreza-Wheel studs nuts

2014 Subaru Impreza wheel studs and nuts

Technical references from Subaru’s 2014 Impreza Factory Service Manual (STIS), the Subaru parts catalogue, and the Owner’s Manual torque recommendations confirm that the 2014 Subaru Impreza is built with pressed-in wheel studs (M12 × 1.25) and matching lug nuts on a five-stud hub (5×100 across the range in 2014). That means wheel studs and nuts are absolutely relevant to this model.

On the 2014 Subaru Impreza, the wheel studs and nuts do the quiet heavy lifting: they clamp the wheel and brake rotor firmly to the hub, keeping everything true when the car brakes, corners, and hits bumps. The studs are pressed into the hub from the rear, the nuts thread onto those studs to provide the clamp load. Done right, they ensure consistent braking and protect the hub, bearings, and tyres from uneven wear.

For regular servicing, this is one of those simple checks that pays off big. Subaru’s documentation specifies torquing the wheel nuts to 120 N·m (about 88–90 ft·lb) on clean, dry threads. That “dry” detail matters—lubricants or anti-seize change friction and can over-stress studs. Hand-start the nuts to avoid cross-threading, then use a calibrated torque wrench in a star pattern to seat the wheel evenly. After any wheel-off job—tyre rotation, brake work, new wheels—re-check torque after 50–100 kilometres.

Signs it’s time for attention include nuts that won’t hold torque, visible thread damage, rust pitting, or a stud that’s stretched (threads look pulled or the shank looks necked). If a nut binds or the hex is rounded, replace it. If a stud spins in the hub or the threads are stripped, replace the stud. Replacement involves pressing or drawing the old stud out and installing a new one square to the hub, on many Subarus, the brake rotor and calliper need to come off for access. Quality studs and nuts with the correct M12 × 1.25 pitch are a must.

• Torque wheel nuts to 120 N·m on clean, dry threads only.
• Hand-start, then tighten in a star pattern, re-torque after 50–100 km.
• Never use anti-seize or oil on studs/nuts, it skews clamp load.
• Inspect at every service or tyre rotation for damage, rust, or stretch.
• If a stud is damaged, replace it promptly to protect the hub and wheel.

Looked after properly, the Impreza’s wheel studs and nuts deliver the reliable clamp force that keeps tyres tracking straight and brakes feeling consistent—exactly what drivers in Australia and New Zealand expect on daily runs and long weekend drives alike.

Popular questions about 2014 Subaru Impreza wheel studs and nuts

What is the correct wheel nut torque for a 2014 Subaru Impreza?

The factory-specified torque is 120 N·m (about 88–90 ft·lb) on clean, dry threads. Use a calibrated torque wrench and tighten in a star pattern to seat the wheel evenly. After fitting wheels or rotating tyres, re-check torque after 50–100 kilometres.

Should anti-seize or lubricant be used on Impreza wheel studs?

No. Subaru’s torque figures assume dry, clean threads. Lubricating the studs or nuts reduces friction, which can over-clamp the wheel and stretch studs, risking failure. If threads are dirty, clean them, if they’re damaged or rusty, replace the affected parts.

How can someone tell a wheel stud or nut needs replacement?

Look for cross-threading, rounded nut hexes, seized or spinning studs, visible rust pitting, or stretched/flattened threads. If a nut won’t hold torque or a stud turns in the hub, it’s time to replace the faulty hardware with correct-spec M12 × 1.25 parts.
