Parts for your 2013 Subaru Exiga-Wheel hubs

2013 Subaru Exiga wheel hubs — what they do and how to look after them

Wheel hubs are absolutely fitted to the 2013 Subaru Exiga. Technical sources including the Subaru Exiga (YA series, MY2013) Service Manual (Chassis/Suspension – Wheel Bearing), the Subaru FAST/Global electronic parts catalogue, and reputable aftermarket catalogues from SKF and NTN all specify sealed front and rear hub unit bearings for this model. That makes wheel hubs relevant to every Exiga on the road.

On the Exiga, each hub unit supports the wheel, keeps the brake rotor centred, and (on driven wheels) mates to the drive axle. The hub assembly houses a sealed bearing that lets the wheel spin smoothly while handling cornering loads. It also integrates the ABS encoder ring, so the vehicle’s stability and traction systems can do their job without drama.

Because the bearings are sealed-for-life, there’s no greasing or adjustment during routine servicing. Instead, the focus is on inspection and tidy installation when replacement is due. A good workshop will check for tell-tales like a humming or growling noise that rises with speed (often from 40–80 km/h), play when rocking the wheel at 12 and 6 o’clock, brake pulsation from rotor runout caused by a worn hub, or an ABS light triggered by a damaged encoder or sensor.

• If replacement’s needed, the Exiga uses complete bolt-in hub units. Swapping the whole assembly is the correct approach.
• Use quality hub units that include a new mounting flange and ensure the ABS encoder matches the vehicle’s sensor type.
• Clean the hub mating face and rotor hat thoroughly, any rust scale can cause brake judder.
• Follow Subaru torque specs for the axle nut and hub bolts, re-torque wheel nuts correctly after a short drive.

There’s no set kilometre interval for hub replacement—many Exiga hubs run well past 150,000 km, but harsh roads, kerb strikes, and oversized wheels can shorten life. During regular servicing (say, every 10,000–15,000 km), it’s smart to listen for bearing noise on a road test, check for play on the hoist, and inspect ABS sensor wiring. Keeping tyres matched and properly inflated also reduces load on the bearings and helps the AWD system stay happy.

Done right, new hubs restore quiet, straight-line tracking and crisp ABS performance—making the Exiga feel tight and tidy again.

Do the 2013 Exiga’s wheel bearings get serviced, or are they sealed?

They’re sealed hub unit bearings, front and rear. That means no greasing or adjustment—when worn, the complete hub assembly is replaced. This design improves durability and keeps water and grit out, which is handy on Kiwi and Aussie roads.

How long do Exiga wheel hubs usually last?

Anywhere from about 100,000 to 200,000 kilometres is common, depending on road conditions, wheel/tyre choices, and driving style. Regular checks during scheduled services help catch early noise or play before it affects brakes or tyres.

Will a failing hub affect ABS or stability control?

Yes. The Exiga’s hub units incorporate the ABS encoder. If the bearing develops play or the encoder is damaged, the ABS or VDC light can appear, and braking performance may be compromised. Correct replacement and clean sensor installation sort this quickly.
