Parts for your 2016 Mitsubishi Asx-Wheel bearings

2016 Mitsubishi ASX wheel bearings — what they do and how to look after them

Wheel bearings are absolutely used on the 2016 Mitsubishi ASX. Technical references including the Mitsubishi ASX/RVR Workshop Manual (Group 26: Front/Rear Axle and Hub), the Mitsubishi Motors ASA electronic parts catalogue for the GA2W/GA3W series, and major bearing catalogues from OEM suppliers (e.g., NSK/SKF hub unit listings) specify sealed, double‑row hub bearings at the front and rear for this model. These are unitised bearings designed to handle radial and axial loads, with ABS tone functionality integrated at the hub.

On the ASX, the wheel bearings let the wheels spin smoothly while carrying the weight of the vehicle and managing cornering and braking forces. Being sealed-for-life hub units, they don’t need regular greasing. What they do need is the owner’s ear and a mechanic’s eye during routine servicing. A healthy bearing is quiet, a tired one often hums or drones with road speed, sometimes changing tone as the steering is gently loaded left or right. Left unchecked, a failing bearing can affect tyre wear, braking stability and ABS/ASC performance.

At service time, a good workshop will road test, then check for roughness, heat, and play at each wheel. They’ll spin the wheel by hand and feel for notchiness, and rock it at the 12 and 6 o’clock positions to pick up any movement. Drivers can help bearings live longer by avoiding hard kerb hits, re‑torquing wheels correctly after tyre work, and keeping clear of deep floodwater where possible. Expect typical life to be well past 100,000 km, but harsh roads, oversized wheels or frequent impacts can bring that forward.

When replacement is due, the ASX uses hub unit bearings: the fronts are typically pressed into the steering knuckle with the hub pressed into the bearing, while many rears are supplied as bolt‑on hub assemblies. It’s a precision job that needs a press, correct drifts/supports, and the right torque on the axle nut and wheel fasteners. Quality OEM-equivalent parts and new retaining hardware are the go. If the knuckle or strut bolts are disturbed, ask for a wheel alignment check. Most of the time only the noisy side is replaced, but a quick inspection of the other side is smart practice.

• Act fast on humming, ABS warnings or heat at a wheel after a drive.
• Use quality hub units and follow torque specs to the letter.
• Get an alignment if suspension bolts were loosened during the job.

How long do wheel bearings last on a 2016 ASX?

Many ASX wheel bearings run well beyond 100,000 km. Life depends on road conditions, wheel impacts, wheel/tyre size, and correct torqueing of the axle nut and wheel nuts. Regular checks during servicing help pick up early signs so they can be sorted before they affect tyres or braking.

What are the common signs of a failing wheel bearing?

A steady humming or growling that rises with speed is the classic clue. The note may change when gently weaving the car. You might also feel vibration through the floor or steering, notice uneven tyre wear, or see ABS/ASC lights if the tone ring or sensor signal is affected.

Can the ASX be driven with a noisy bearing?

It’ll usually still roll, but it’s not a good idea. A worn bearing can heat up, increase stopping distances and, in extreme cases, risk hub damage. Book it promptly and avoid long motorway hauls until it’s inspected.
