2015 Mitsubishi ASX Wheel Studs & Nuts — What They Do and How to Look After Them

Based on technical references — including the Mitsubishi Motors 2015 ASX/Outlander Sport Owner’s Manual (wheel removal and refit section referencing “wheel nuts”) and the Mitsubishi service/workshop manual hub assembly diagrams that show pressed-in wheel studs with separate nuts — the 2015 Mitsubishi ASX uses wheel studs and nuts rather than wheel bolts. In short, it’s a five-stud hub with separate lug nuts securing the wheel to the hub.

On the ASX, the wheel studs are the fixed, threaded pins pressed into the hub, while the nuts clamp the wheel’s tapered seats onto the hub face. This combo keeps the wheel centred and properly clamped so the tyre tracks straight and the brakes do their job without vibration. It’s the tried-and-true setup used on most Japanese-built vehicles of the era.

As part of regular servicing, a quick health check of the studs and nuts pays off. Look for:

• Damaged or stretched threads, rusty or pitted studs, and deformed or rounded nuts
• Tapered seats in the nuts that are chewed out or discoloured from overheating
• Any stud that spins in the hub (it should be solidly pressed in)

When wheels are refitted, they should be snugged in a star pattern, then torqued accurately with a torque wrench — not rammed home with an impact gun. Avoid lubricating the threads or the nut seats, as that can distort clamping force, if needed, a light smear of anti-seize can go on the hub face only to prevent the wheel from sticking, never on the threads. After any wheel-off service, it’s smart practice to re-check the nut torque after 50–100 km.

Replacing a dud nut is straightforward: swap it for a quality item with the correct thread and a 60° tapered seat to match the ASX’s wheels. If a stud is damaged, it’s pressed out and a new one is pressed in from the rear of the hub. Depending on access, the hub may need to come off the vehicle. If multiple nuts show wear or corrosion, replacing them as a set keeps clamping even and tidy.

Key signs it’s time to act include a clicking noise on acceleration or braking, steering wheel vibration, or finding a nut that won’t hold torque. A quick inspection during tyre rotations or brake services keeps everything sweet and safe for the long haul.

• What thread size are the 2015 ASX wheel nuts?
  Most 2015 Mitsubishi ASX models use M12 x 1.5 studs with 60° taper-seat nuts. Variants and wheel types can differ, so it’s best to confirm against the vehicle’s handbook or by VIN before ordering parts.
• How often should the wheel nuts be re-checked?
  Any time the wheels have been off, re-check nut torque after 50–100 km of driving. It’s also worth verifying torque at routine services or if you feel any new vibration.
• Can a single damaged stud be replaced?
  Yes. Individual studs can be pressed out and replaced. If several nuts or studs show wear or corrosion, replacing them as a matched set helps maintain even clamping and reduces future hassles.
