Parts for your 2011 Subaru Exiga-Wheel hubs

2011 Subaru Exiga wheel hubs: what they do, why they matter, and when to replace them

Wheel hubs are absolutely fitted to the 2011 Subaru Exiga and are integral to its suspension and braking systems. Technical references including the Subaru Exiga (YA series, MY2011) service manual (Chassis and Brake sections) and the Subaru FAST electronic parts catalogue list unitised front and rear wheel hub assemblies with integrated bearings and ABS encoder rings for this model. Major aftermarket catalogues from SKF, NTN-SNR and NSK also catalogue complete hub units for the 2011 Exiga, confirming fitment.

On the Exiga, the wheel hub sits between the drive shaft/knuckle and the wheel. It supports the vehicle’s weight via the bearing, keeps the wheel running true, and provides the mounting face for the wheel studs. The integrated ABS encoder supplies wheel speed data for ABS and stability control. With Subaru’s AWD system, a healthy hub is critical to keep everything smooth and to prevent driveline vibrations and uneven tyre wear.

There’s not much day-to-day maintenance to do on sealed hub units, but regular checks during servicing pay off. A tech will spin each wheel and listen for a grumble, check for play at 12 and 6 o’clock, and scan for ABS faults. They’ll also inspect wheel studs and nuts, look for rust jacking on the hub face, and ensure wheels are torqued correctly (wheel nuts typically around 120 Nm for Subaru passenger models).

• Common signs a hub’s on the way out: humming that grows with road speed, a cyclic grind on turns, ABS warning lights, uneven tyre wear, or warmth at the hub after a short drive.
• Helpful tips: keep wheels torqued evenly, avoid kerb hits, and clean the hub face when rotating tyres to prevent runout.

When a hub fails, the Exiga uses a bolt-in unit, so replacement involves removing the caliper and rotor, undoing the axle nut, unbolting the hub from the knuckle, and disconnecting the ABS lead. It’s smart practice to use a new staked axle nut and follow factory torque specs (axle nut commonly in the 220–240 Nm range, always confirm in the Subaru service data). Avoid hammering on the bearing, keep the hub face clean, and recheck wheel alignment if there was play beforehand. Quality hub assemblies from known bearing makers tend to run quieter for longer, which matters on Aussie and Kiwi roads with plenty of coarse-chip surfaces. If swapping wheels, ensure the 5x100 PCD and correct centre bore fitment to stay hub-centric and vibration-free.

Popular questions about 2011 Subaru Exiga wheel hubs

Does the 2011 Exiga use hubs with integrated bearings?
Yes. The 2011 Exiga uses sealed, unitised hub assemblies front and rear, with the wheel bearing and ABS encoder built in. The bearing isn’t designed to be serviced separately, so the whole hub unit is replaced if it’s worn or noisy.

How long do the hubs typically last?
It varies with driving and road conditions, but many will see 100,000–200,000 km or more. Frequent gravel use, heavy loads, aggressive tyres, or impacts with potholes can shorten lifespan. Early signs like a faint hum or ABS light should be checked promptly.

What are the key specs to know when servicing?
The Exiga runs a 5x100 stud pattern and a Subaru-standard hub-centric centre bore. Wheel nut torque is typically around 120 Nm, and the front axle nut commonly tightens in the 220–240 Nm range. Always confirm the exact figures in the Subaru service manual for the specific variant.
