Parts for your 2017 Subaru Exiga-Wheel hubs

2017 Subaru Exiga wheelhubs – purpose, service and when to replace

Based on technical sources including the Subaru Exiga Crossover 7 (YAM) service manual (Front/Rear Axle – Hub Unit Bearing sections), the Subaru FAST electronic parts catalogue for the 2017 Exiga, and major bearing makers’ catalogues (e.g., NTN/NSK/SKF listings for Exiga/Crossover 7), the 2017 Subaru Exiga is fitted with bolt-on unitised wheel hub and bearing assemblies at both the front and rear. Wheel hubs are therefore absolutely relevant to this model.

The wheel hub on a 2017 Subaru Exiga carries a few key jobs: it centres and secures the wheel via the studs, supports vehicle weight through a sealed bearing, and feeds wheel-speed data to the ABS/ESC via an integrated tone ring. On the road, a healthy hub keeps the Exiga smooth and quiet, the steering tight, and the tyres wearing evenly. Because the bearings are sealed-for-life, there’s no greasing—service is about smart inspection and timely replacement when wear shows up.

During routine servicing or a tyre rotation, technicians should spin each wheel and listen for a coarse rumble, check for play at 12-and-6 o’clock, and look for ABS faults. Any knocking, cyclic humming that grows with speed, ABS light with a wheel-speed code, or heat at the hub after a drive are red flags.

• Common signs a hub is failing: humming/growling above 40–60 km/h, play in the wheel, uneven tyre wear, ABS/ESC warnings, or a hot hub flange.

Replacement on this Exiga is straightforward but precise: the unit bolts to the knuckle. Typical steps include removing the wheel, brake caliper and rotor, unplugging the wheel-speed sensor, releasing the staked axle nut, then undoing the hub bolts from the back of the knuckle. Corrosion can make the old hub stubborn, so expect some persuasion and surface cleaning before fitting the new unit. The new hub should be OEM-quality (Subaru/NTN/NSK) and installed with a new axle nut. Wheel nuts and the axle nut must be torqued to the Subaru spec and the axle nut re-staked. A short road test to verify ABS readings and noise levels wraps the job.

As a maintenance habit, keep wheel nuts correctly torqued, avoid blasting the hub area with a pressure washer, and organise inspections every 10,000–15,000 kilometres with tyre rotations. That approach keeps the 2017 Subaru Exiga wheelhubs quiet, safe, and happy for the long haul on Aussie and Kiwi roads.

Popular questions about 2017subaruexiga wheelhubs

What are the tell-tale symptoms of a bad wheel hub on a 2017 Subaru Exiga?

Owners often notice a humming or growling that rises with road speed, sometimes changing when cornering. There may also be a slight vibration through the seat or steering, uneven tyre wear, or an ABS/ESC light triggered by erratic wheel-speed signals.

On a hoist, a worn hub can show roughness when spun by hand or free play when rocked at the rim. A quick post-drive touch test (carefully) may reveal an unusually hot hub compared with the others.

How long do wheel hubs typically last on a 2017 Subaru Exiga?

With normal driving and regular rotations, sealed hub units commonly run 120,000–200,000 kilometres. Rough roads, frequent water crossings, heavy loads, or oversized wheels can shorten that window. Routine checks at each service help catch issues early.

Quality matters: OEM or reputable-brand hubs tend to last longer and stay quieter, especially important for long-distance touring common in Australia and New Zealand.

Can the bearing be replaced separately, or is it a full hub swap on this model?

For the 2017 Exiga, the design is a unitised hub-and-bearing assembly, so service procedure is to replace the complete hub unit. This avoids press work and ensures correct preload and sealing.

While some aftermarket options may list separate bearings, the proper repair for this chassis is the bolt-on hub unit, which restores fit, ABS compatibility, and long-term reliability.
