Parts for your 2014 Subaru Exiga-Wheel hubs

2014 Subaru Exiga wheel hubs: what they do and when to replace them

Wheel hubs are absolutely used on the 2014 Subaru Exiga (YA-series). Subaru’s Factory Service Manual for the Exiga (front suspension and rear axle sections) and the Subaru FAST electronic parts catalogue both specify bolt-in, unitised hub-and-bearing assemblies at all four corners, with integrated ABS tone functionality. That makes wheel hubs directly relevant to any servicing or repairs on a 2014 Exiga.

On this Exiga, each wheel hub is a sealed “hub unit bearing”. It supports the vehicle’s weight, keeps the wheel running true, and lets the driveshaft (front and many rears on AWD) transfer torque smoothly. The hub also carries the wheel studs and works with the ABS/Vehicle Dynamics Control via a built-in tone ring or encoder. Because it’s a sealed unit, there’s no greasing or rebuilding during routine servicing — when it’s worn, the whole assembly is replaced.

For day-to-day care, the best approach is regular inspection. During scheduled services or tyre rotations, a tech should spin each wheel and check for roughness, listen for humming, and feel for play. With the wheel off, they’ll check the hub face for corrosion, confirm stud condition, and ensure wheel nuts are torqued to spec (typically around 120 N·m — always follow the Subaru spec for the exact model/trim). Avoiding harsh kerb hits, keeping tyres correctly inflated, and washing off road salt or coastal spray will all help the hubs and bearings live a long life.

When a hub is on the way out, it usually tells a story:

• A speed-related hum or growl that gets louder when cornering one way.
• Disc heat or drag on one corner after a short drive.
• ABS/VDC warning light triggered by a noisy encoder signal.
• Noticeable wheel play felt at 12 and 6 o’clock when the wheel is lifted.

Replacement on the Exiga involves removing the brake assembly, splitting the lower arm or strut bolts as needed, undoing the four hub bolts from the knuckle, and removing the staked axle nut where applicable. The new unit bolts straight in. It’s smart to replace the axle nut, clean mating surfaces, and torque everything to the Subaru spec. After front hub work, a wheel alignment check is a good idea. Quality matters here — genuine or reputable aftermarket hub units tend to be quieter and last longer. If one side has failed at high kilometres, inspecting the opposite side is worthwhile.

• Handy servicing tip: don’t lean on rattle guns for the axle nut with the vehicle’s weight on the wheel, stake a new nut after torquing, and clear any rust from the knuckle bore so the new hub seats square.

Popular questions about 2014 Subaru Exiga wheel hubs

How can someone tell a hub bearing is failing on a 2014 Exiga?
Common clues are a droning or humming that changes with road speed and gets louder turning one way, slight steering vibration, or an ABS/VDC light due to a noisy encoder signal. With the wheel lifted, any roughness when spinning by hand, or play felt at 12 and 6 o’clock, also points to a worn hub unit.

Do Exiga hub bearings need regular greasing?
No. They’re sealed hub unit bearings. There’s no scheduled greasing — just periodic checks for noise, play, and stud condition. Keeping wheel nuts correctly torqued and tyres balanced helps them last longer.

What’s the stud pattern on a 2014 Exiga?
The 2014 Subaru Exiga typically uses a 5x100 PCD with a 56.1 mm centre bore. Always confirm against the vehicle’s build plate or parts catalogue for trim-specific variations before ordering wheels or hubs.
