2015 Mitsubishi ASX Wheel Hubs — What They Do and When to Replace Them

Wheel hubs are absolutely fitted and relevant on the 2015 Mitsubishi ASX. Technical references include the Mitsubishi Motors Workshop Manual for ASX/Outlander Sport (2010–2017), Group 26 (Front Axle) and Group 27 (Rear Axle), which detail unitised hub-and-bearing assemblies, and the Mitsubishi ASA Electronic Parts Catalogue for GA2W/ASX listings that show “FR WHEEL HUB & BEARING” and “RR HUB & BEARING” with integrated ABS encoder rings. Major bearing manufacturers’ application catalogues for this model also specify sealed hub units for both front and rear positions.

On a 2015 ASX, each wheel bolts to a hub assembly that houses a sealed, double-row bearing. Up front (FWD and AWD), the hub is splined to the driveshaft, at the rear, it’s a bolt-on hub unit (driven on AWD, non-driven on FWD). The hub keeps the wheel running true, supports vehicle load, and provides a mounting face for the brake disc. It also carries the ABS tone ring or encoder, so a worn hub can cause both noise and ABS warning lights.

Because the bearings are sealed, there’s no greasing during routine servicing. Instead, servicing focuses on inspection and correct fitment when replacement is needed. Typical tell-tales that the ASX hub is on the way out include a low rumble that follows road speed, a droning that changes when cornering, play felt at the wheel with the car jacked up, uneven or cupped tyre wear, and an intermittent ABS light. Any noticeable looseness or roughness when the wheel is spun off the ground is a red flag.

Replacement is straightforward for a trained tech: remove the caliper and rotor, unbolt the hub assembly from the knuckle (or trailing arm at the rear), and refit a quality unit. On the front, the axle nut must be torqued to the factory spec and replaced if specified by Mitsubishi. The hub face and rotor hat should be cleaned of rust and debris to prevent brake judder. If the strut-to-knuckle bolts are disturbed, a wheel alignment check is a smart move.

In Aussie and Kiwi conditions, a good hub can last well beyond 120,000 km, but rough roads, water ingress, or a hard kerb strike can shorten life. It’s not mandatory to replace hubs in pairs, though many workshops do so to keep noise and feel consistent across an axle. During regular services, a quick road test for bearing noise, a spin-and-feel check with wheels off the ground, and a visual of ABS wiring near the hubs will keep the ASX rolling quietly and safely.

• Watch for speed-related rumble, wheel play, and ABS warnings.
• Use OE-equivalent hub units, don’t re-use staked axle nuts if the manual says replace.
• Clean hub and rotor mating faces to avoid brake pulsation.

Popular questions about 2015 Mitsubishi ASX wheel hubs

How can someone tell if their ASX wheel hub is failing?
Most drivers notice a humming or droning that gets louder with road speed and often changes when gently weaving. With the car safely lifted, any roughness when spinning the wheel, or noticeable play at 12 and 6 o’clock, points to a worn hub. An ABS warning light after rain or a pothole hit can also be linked to the hub’s encoder or sensor.

Do the hubs on a 2015 ASX need regular greasing?
No. The ASX uses sealed, unitised hub-and-bearing assemblies. There’s no scheduled greasing—once they wear or get noisy, the fix is replacement. Regular servicing should include checks for noise, play, and sensor wiring condition.

Is a wheel alignment needed after hub replacement?
Often no, but it depends on what’s loosened. If the knuckle-to-strut bolts are left untouched, alignment typically won’t change. If those bolts are moved, or if there was uneven tyre wear beforehand, getting an alignment is a wise precaution.
