Parts for your 2012 Mitsubishi Lancer-Wheel hubs

2012 Mitsubishi Lancer wheel hubs: purpose, care, and when to replace

Wheel hubs are absolutely used on the 2012 Mitsubishi Lancer. The Mitsubishi Lancer CJ/CF Workshop Manual (front axle Group 26, rear axle Group 27) and the Mitsubishi ASA parts catalogue list both front and rear hub and bearing arrangements for this model year. Front bearings are press-fitted into the steering knuckle with the hub, while the rear typically uses a bolt-on hub unit (disc-brake models) or an integrated drum hub (drum-brake variants). Major bearing manufacturers’ catalogues for 2012 Lancer applications corroborate these hub assemblies.

On a 2012 Lancer, the wheel hub’s job is to keep the wheel securely mounted and spinning freely and true. It carries the wheel studs, supports the vehicle’s weight through a sealed bearing, and provides the mounting face for the brake rotor or drum. Many variants also integrate the ABS tone ring or provide the mounting surface for the ABS sensor, so the hub assembly plays a role in brake stability control too.

There’s no scheduled replacement for Lancer wheel hubs, they’re sealed, non-serviceable units. As part of regular servicing (every 10,000–15,000 km in Aussie and Kiwi conditions), a quick hub check is smart: spin each wheel by hand with the car safely lifted, feel for roughness, and listen for humming. A technician can also check for play by rocking the tyre at 12 and 6 o’clock and measure run-out if there’s vibration. Keep tyres balanced and aligned and avoid kerb hits and potholes to extend hub life.

When a hub does fail, a faint drone that rises with road speed is the classic giveaway, sometimes changing when steering left or right. Braking wobble, uneven tyre wear, or an ABS light can also point to hub or bearing issues. Most last well beyond 150,000 km, but rough roads, water ingress, or wheel impacts can shorten that.

Replacement notes: the front bearing/hub is a press-fit job requiring a press, new circlip, and typically a new axle nut, the rear hub unit bolts to the trailing arm or rear knuckle. Torque specs and procedures vary by variant (ES/VR/VRX/Ralliart/Evolution), so follow the Mitsubishi workshop manual. Don’t hammer on the studs, protect the ABS sensor, and torque the axle nut and caliper bracket bolts to spec in Newton-metres. If one side is noisy, it’s fine to replace just that side, though some owners choose pairs for even wear and downtime.

• Common symptoms: humming/growling with speed, steering vibration, ABS light, play at the wheel, uneven tyre wear.
• Good habits: correct wheel torque, balanced tyres, avoid deep water and hard kerb strikes.

FAQs

Does the 2012 Mitsubishi Lancer use serviceable (greasable) bearings or sealed hub units?

They’re sealed bearings and hub units, not greasable. The fronts are press-fit bearings inside the knuckle with the hub, and the rears are typically bolt-on sealed hub assemblies or integrated drum hubs. When worn, the unit or bearing is replaced rather than repacked.

What are the signs a Lancer wheel hub is failing?

A steady humming or growling that scales with speed is most common, often changing when you gently weave the car. You might also notice vibration through the wheel, uneven tyre wear, ABS warnings, or detectable play when rocking the tyre at 12 and 6 o’clock.

Do I need to replace wheel hubs in pairs?

Not strictly. If only one side is noisy or has play, replacing that side is acceptable. That said, on higher-kilometre cars or when labour access is significant, some owners choose to do both sides on the same axle for convenience and consistent wear.
