Parts for your 2015 Subaru Exiga-Wheel bearings

2015 Subaru Exiga wheel-bearings

Wheel bearings are absolutely relevant to the 2015 Subaru Exiga. Subaru’s own technical material confirms it: the Exiga (YA series, MY2015) uses sealed, bolt-on hub unit bearings at all four corners, with integrated ABS encoder rings. This is documented in Subaru’s workshop/service manual sections for Front/Rear Axle Hub Unit Bearings and in the Subaru FAST parts catalogue for the YA-model Exiga.

On this people mover, the wheel bearings support the vehicle’s weight, let the wheels spin smoothly, and keep everything tracking straight through day-to-day driving and family road trips. Because they’re sealed hub units, there’s no routine greasing—when they wear, the whole hub assembly is replaced. That sealed design boosts reliability, keeps water and grit out, and ensures the ABS sensor reads cleanly from the built-in magnetic encoder.

As part of normal servicing, the workshop should road test for a low, speed-dependent hum or growl that gets louder when turning one way, then check for free play with the wheel off the ground. On the Exiga, a failed bearing can also upset ABS readings, so an unexpected ABS light after rain or a pothole hit can be a clue.

• Common symptoms:
  • Humming or droning that changes with speed or when loading one side
  • Play felt at 12-and-6 o’clock when the wheel is rocked
  • ABS warning light or erratic speed-sensor readings
  • Uneven tyre wear or a hot hub after a drive

Service tips for a 2015 Exiga hub unit replacement: use quality, VIN-matched hubs with the correct ABS encoder. Avoid hammering—the hub bolts off the knuckle, so it’s a straight swap rather than a press-in job on this model. Clean the mating face, torque all fasteners correctly, and install a new axle nut where specified. An alignment check isn’t usually required for a hub swap, but if the knuckle-to-strut bolts were loosened, it’s smart to verify alignment.

There’s no fixed replacement interval, many last well beyond 150,000 km, but rough roads, big potholes, or oversized tyres can shorten life. A quick bearing check every service (10,000–15,000 km is typical in Australia and New Zealand) helps catch issues early. Keeping tyres balanced, wheel nuts correctly torqued, and avoiding pressure-washing directly at the hub area will also help bearings go the distance.

Popular questions about 2015 Subaru Exiga wheel bearings

How long do the Exiga’s wheel bearings usually last?
With careful driving and regular servicing, many owners see 100,000–200,000 kilometres or more. Harsh road conditions, kerb hits, and heavy loads can bring that down. Once a bearing starts humming or shows play, replacement is the go—there’s no benefit in waiting.

Can the Exiga’s wheel bearings be greased or adjusted?
No—this model uses sealed hub unit bearings. They’re pre-greased for life at the factory and aren’t serviceable. If a bearing is noisy or loose, the complete hub assembly is replaced.

Are front and rear Exiga hubs the same, and do they affect ABS?
Front and rear hub units differ, and they’re model- and VIN-specific because the ABS encoder is built in. Fitting the wrong hub can trigger ABS faults. Always match the part number to the vehicle, and keep the sensor and encoder face clean during installation.
