Parts for your 2017 Subaru Exiga-Wheel bearings

2017 Subaru Exiga wheel bearings: purpose, service tips, and when to replace

Wheel bearings are absolutely used on the 2017 Subaru Exiga. Technical references such as the Subaru Factory Service Manual for the YA-series Exiga/Crossover 7 (MY2017) and Subaru parts catalogues specify sealed front and rear hub unit bearings with integrated ABS encoder rings. In other words, every Exiga wheel rides on a sealed hub-and-bearing assembly designed for the model’s AWD layout and family-hauling duties.

On this Exiga, the wheel bearings support vehicle weight, keep the hub and wheel rotating smoothly, and maintain precise alignment of the brake rotor and ABS components. They’re sealed, pre-greased assemblies, so there’s no periodic greasing—when worn, they’re replaced as a unit. This design boosts reliability and keeps contaminants out, which suits Aussie and Kiwi roads ranging from motorways to coarse chip and gravel.

Signs the bearings are tired typically arrive as speed-related humming or a droning growl that changes when the steering is nudged left or right. A failing unit can also trigger an ABS warning if the encoder signal goes off-spec, or cause uneven tyre wear and heat at the affected hub after a drive.

As part of routine servicing, workshops usually road test for noise, check for play at 12-and-6 o’clock on the wheel, spin the hub with the caliper off to feel for roughness, and scan for ABS faults. There’s no fixed change interval—healthy Exiga bearings often run well past 100,000 kilometres—but frequent water crossings, potholes, kerb strikes, oversized wheels, and hard loads shorten their life.

When replacement is due, quality matters. A good hub assembly with the correct magnetic encoder specification for Subaru systems helps avoid ABS gremlins. Correct axle-nut torque and clean mounting faces are critical to longevity, over- or under-tightening will kill a new bearing quickly. It’s also wise to rotate tyres regularly and keep pressures in check, as excess load and heat accelerate bearing wear.

Owners who keep the Exiga’s suspension bushes, shocks, and alignment tidy will get the quietest ride and the longest bearing life. If a humming starts, sorting it promptly protects the hub, brakes, and even the CV joint—leaving a noisy bearing to escalate can get expensive fast.

• Common symptoms: humming/growling with speed, ABS light, heat at the hub, uneven tyre wear.
• Service checks: wheel play, smooth hub rotation, road test, ABS scan.
• Best practice: use quality sealed hub units, match ABS encoder type, torque to factory spec.

Popular question: What are the classic symptoms of a bad wheel bearing on a 2017 Subaru Exiga?

Most owners notice a steady hum or droning that gets louder with road speed and often changes tone when gently weaving the vehicle. There may be a faint vibration through the floor, heat around the suspect hub after a drive, or an ABS light if the encoder signal degrades. Tyres can start feathering when play develops.

On a hoist, a tech will feel roughness when spinning the wheel and detect play at the rim. Because road noise and tyre patterns can mimic bearing noise, a proper road test and side-to-side load test helps confirm the culprit.

Popular question: How long do Exiga wheel bearings last, and is there a service interval?

There’s no set interval because the bearings are sealed-for-life units. Many Exigas see well over 100,000 kilometres before any sign of wear, while vehicles that tow, run oversized wheels, or see frequent water and corrugations may need them earlier.

Regular servicing should include checks for noise and play. Replacement is recommended at the first confirmed signs of roughness or looseness to protect hubs, brakes, and CVs and to keep ABS happy.

Popular question: Is it safe to keep driving with a noisy wheel bearing?

It’s not recommended. A noisy bearing can heat up, increase stopping distances, upset ABS readings, and, in worst cases, seize or allow excess wheel movement. The longer it’s left, the higher the chance of collateral damage and the bigger the bill.

Short trips to a workshop are generally fine if the vehicle is driven gently, but delaying repair isn’t worth the risk on a family-hauling Exiga.
