2014 Subaru XV Wheel-Bearings: What They Do and When to Replace Them

Wheel-bearings are absolutely used on the 2014 Subaru XV (GP platform). The Subaru Factory Service Manual for the 2014 Impreza/XV and the Subaru FAST parts catalogue specify sealed hub unit bearings fitted at all four corners, designed to be replaced as assemblies rather than serviced. Major bearing manufacturers’ catalogues (SKF/NSK/NTN) also list hub unit bearings for this model, confirming fitment and type.

On the XV, the wheel-bearings do the heavy lifting of supporting vehicle weight while letting the wheels spin smoothly with minimal friction. They keep the wheel and brake rotor running true, help maintain proper tyre contact, and provide a clean signal to the ABS/ESC via the integrated encoder ring. Because the XV is AWD, tight tolerances in the bearings also help keep driveline loads happy and noise down on the open road.

These bearings are sealed for life, so there’s no greasing or adjustment during routine servicing. Instead, servicing is about inspection and replacement when needed. During scheduled services, a technician checks for play and roughness at each hub, listens for humming or growling that changes with speed or when loading the car in a gentle lane change, and looks for ABS faults that can point to a failing encoder.

• Common signs: a droning/whirring that gets louder with road speed, a change in tone when steering left/right, heat at the hub after a drive, ABS light, or uneven tyre wear.
• Typical life: often 120,000–200,000 km, but heavy loads, off‑road work, potholes, or water crossings can shorten it.

When replacement is needed, the Subaru FSM calls for swapping the complete hub unit. It’s a bolt-on job on this generation, but it still needs proper axle nut torque, care around the ABS sensor and encoder, and new hardware where specified. After fitting, a short road test to confirm noise is gone and an alignment check (if the knuckle was disturbed) are smart moves. Quality OEM-spec hubs are worth it, they tend to run quieter and last longer.

It isn’t mandatory to replace bearings in pairs on this model—only the noisy or loose side needs doing—though high‑kilometre vehicles may benefit from doing the other side if it’s starting to rumble as well.

Popular questions about 2014 Subaru XV wheel-bearings

What noise does a failing wheel-bearing make on a 2014 XV?
Usually a low, steady hum or growl that rises with road speed. It often changes when the car is gently steered left or right, loading and unloading the suspect side. Tyre roar can sound similar, so a proper hub play/roughness check helps confirm it.

How long does a wheel-bearing last on a 2014 XV?
Many go 120,000–200,000 km. Rough roads, bigger tyres, frequent water crossings, or curb strikes can bring that down. Regular inspections during services help catch early signs before it becomes a safety issue.

Should both front or both rear wheel-bearings be replaced together?
Not strictly. The failed side can be replaced on its own. If the opposite side shows noise or play, or the vehicle has high kilometres and similar wear conditions, doing both can save a second visit.
