Parts for your 2012 Subaru Exiga-Wheel hubs

2012 Subaru Exiga wheel hubs

Wheel hubs are absolutely fitted to the 2012 Subaru Exiga. Technical documentation backs this up: the Subaru Exiga (YA) Service Manual (Chassis – Front Axle/Rear Axle) specifies hub unit bearings at each corner, the Subaru FAST parts catalogue lists “front hub unit bearing” and “rear hub unit bearing” for MY2012 Exiga variants, and major bearing manufacturers’ catalogues (e.g., NTN/NSK) include complete hub assemblies for the YA-series Exiga. So yes, wheel hubs are relevant to this vehicle.

On the 2012 Subaru Exiga, the hub unit bearing is the bit that the wheel bolts to and the brake rotor locates on. It centres the wheel, houses the sealed bearing, and interfaces with the driveshaft on AWD models. Many assemblies also carry the ABS tone ring or encoder for the wheel speed sensor. In short, the hub keeps everything rolling smoothly and square, while talking nicely to the ABS and stability systems.

As part of routine servicing, it’s smart to listen for low, speed-dependent growls and check for play. The hub bearing is sealed, so there’s no greasing to do, the job is to spot wear early and replace the assembly when needed. When swapping a hub, follow factory torque specs for the axle nut and caliper hardware, and make sure the mating faces (knuckle, rotor, wheel) are clean so the rotor and wheel sit true. If the Exiga variant uses a bolt-in hub unit, no press is required, if it’s a press-in bearing style, the knuckle needs to come off and the bearing pressed with the correct adapters to avoid brinelling or sensor ring damage.

• Common signs a hub’s on the way out:
  • A rumbling or humming that changes with road speed, not engine revs
  • ABS light or pulsation due to a damaged encoder ring
  • Play felt at 12-and-6 o’clock when rocking the wheel, or uneven tyre wear
• Good practice:
  • Inspect during tyre rotations and brake services
  • Replace fasteners where specified and recheck wheel alignment afterwards
  • Use quality hub units to avoid noise or ABS issues down the track

Look after the hubs and bearings, and the Exiga will stay quiet, sure-footed, and kinder to its tyres over long Kiwi and Aussie kilometres.

FAQs

How long do wheel hubs last on a 2012 Subaru Exiga?
With normal driving, many Exiga hub bearings will run well past 120,000–180,000 km. Harsh roads, big potholes, or oversized wheels can shorten their life. Regular checks during services help catch issues early.

What are the tell-tale signs of a failing hub or bearing?
A steady humming or growling that rises with speed, slight steering wheel vibration, ABS warning lights, or roughness when spinning the wheel by hand are common clues. Any free play at the wheel is a red flag.

Can a home mechanic replace the hub on this model?
Yes, with the right tools and information. Some Exiga variants use bolt-in hub units, which are straightforward. Others use press-in bearings that require a quality press and adapters. If unsure, it’s worth leaving the press work to a workshop.
