2016 Mitsubishi ASX Wheel Hubs — What They Do and When to Replace

Wheel hubs are absolutely used on the 2016 Mitsubishi ASX. Technical references back this up: the Mitsubishi Motors Service Manual for RVR/ASX/Outlander Sport (GA series) details the front and rear wheel hub and bearing units in Group 26A (Front Axle) and Group 27A (Rear Axle). The Mitsubishi ASA electronic parts catalogue lists dedicated hub assemblies with integrated bearings and ABS encoders for this model year, and major fitment catalogues used in Australia and New Zealand (e.g., Repco/NAPA listings and SKF/NTN/NSK application data) carry direct-fit hub bearing units for the 2016 ASX. Haynes service literature for the platform also covers hub/bearing inspection and replacement, confirming the part’s presence and servicing approach.

On a 2016 ASX, the wheel hub assembly is a sealed unit that supports the wheel and brake rotor, houses the bearing, and provides the mounting face for the wheel. It keeps the wheel turning smoothly while handling cornering loads and braking forces, and it carries an encoder for the ABS/ASC system so the car knows each wheel’s speed. Because the bearing is sealed, there’s no periodic greasing—the focus is on inspection and correct installation when replacement is needed.

Signs it’s time to replace a hub include a humming or growling that rises with road speed, a droning noise when cornering, ABS/ASC warnings, or detectable play when the wheel is rocked at 12 and 6 o’clock. Tyre roar can sound similar, so a proper road test and on-hoist check (with the brake caliper free and the hub spun by hand) helps confirm the fault.

During regular servicing, it’s smart to listen for bearing noise on the road test, check for play, inspect ABS wiring at the hub, and make sure wheel nuts are torqued correctly. Avoid blasting the hub area with a pressure washer—water intrusion and harsh cleaners can shorten bearing life.

When replacement is due, the ASX typically takes a complete bolt-on hub assembly. Use quality OEM-equivalent parts, renew any one-time-use axle nuts or bolts, and follow factory torque specs. Keep the ABS sensor and encoder ring clean and aligned. An alignment isn’t normally required for hub replacement, but a quick post-repair road test to verify noise is gone and ABS is happy is a must.

• Watch for: humming/droning noises, ABS lights, wheel play, uneven tyre wear.
• Good practice: torque wheel nuts properly, protect ABS wiring, use correct hub fastener torques.

FAQs

Does the 2016 ASX use a pressed-in bearing or a bolt-on hub assembly?
It uses a bolt-on hub assembly with an integrated sealed bearing. That means when the bearing fails, the whole hub unit is replaced rather than pressing a separate bearing in and out. This approach speeds up the job and reduces the risk of damaging the bearing during installation.

What are the common symptoms of a failing wheel hub on an ASX?
The big giveaway is a humming or growling that increases with speed and often changes when turning slightly left or right. You might also feel roughness when spinning the wheel by hand, notice ABS/ASC warning lights if the encoder signal is affected, or detect play at the wheel.

Can you keep driving with a noisy hub bearing?
It’s not a great idea. A worn hub can get worse quickly, affect braking stability, trigger ABS faults, and in the worst cases lead to excessive wheel play. It’s safer to book a replacement soon after symptoms appear to avoid collateral damage to tyres, brakes or sensors.
