Parts for your 2013 Subaru Tribeca-Wheel bearings

2013 Subaru Tribeca wheel bearings: what they do and when to replace

Technical sources including the Subaru Factory Service Manual for the 2013 Tribeca (Front/Rear Axle “Hub Unit Bearing” sections) and Subaru genuine parts catalogues list sealed hub-unit wheel bearings fitted at all four corners of the vehicle. Major OE bearing manufacturers’ catalogues for this model also specify complete bolt-in hub assemblies. So yes—wheel bearings are absolutely used on the 2013 Subaru Tribeca.

On the Tribeca, the wheel bearing is part of a sealed hub unit. Its job is to let the wheel and brake rotor spin smoothly while keeping everything properly aligned under the weight of the car and through cornering, braking, and rough roads. Because it’s sealed, there’s no greasing during routine service, when it wears out, the whole hub assembly is replaced.

There’s no set replacement interval. Most owners will see well over 100,000 km, but life varies with road conditions, heavy loads, kerb strikes, and water or mud exposure. A worn bearing often makes a constant rumble or growl that rises with road speed, may change when gently weaving, and can cause vague steering, uneven tyre wear, or ABS warnings (the encoder ring and sensor sit with the hub).

Good servicing practice for a Tribeca includes a quick wheel-bearing check at each service: spin each wheel off the ground and listen for roughness, feel for play at 12 and 6 o’clock, and inspect the ABS sensor lead where it enters the hub. Tyre rotations every 10,000 km help catch early noise changes.

When replacement is due, the job is a bolt-in swap rather than a press fit. A competent home mechanic with quality tools can manage it, but many owners prefer a workshop because correct torque and rusted fasteners can be tricky. Always follow the Subaru service manual for procedures, use a new axle nut and any one-time-use bolts if specified, torque everything to spec, and keep the ABS sensor clean and correctly routed. After front hub work, a wheel alignment check is a smart move.

Quality matters. Choose an OE Subaru hub or an OE-equivalent from reputable brands. Avoid bargain hubs with unknown encoder polarity, as the wrong encoder can trip ABS/traction control faults. If one front hub fails at high kilometres, consider the other side may not be far behind—but it’s fine to replace only the noisy one if the rest are healthy.

• Watch for symptoms: humming with speed, ABS light, heat at the wheel, free play.
• Avoid pressure-washing directly at the hub face and don’t hang the brake calliper by its hose during work.
• Torque wheel nuts evenly to the correct spec after any wheel or hub service.

Popular questions

How can someone tell which Tribeca wheel bearing is noisy?

Road test on a smooth road: a worn bearing hums with speed and often changes tone when gently steering left or right, loading the opposite side. A mechanic can confirm on a hoist with a stethoscope and by checking for play at the wheel. Tyre roar can mimic a bad bearing, so ruling out cupped tyres is key.

Is it safe to drive a 2013 Tribeca with a rumbling wheel bearing?

Not recommended. Bearings can deteriorate quickly, affecting braking, ABS operation and steering stability. Severe cases can overheat or damage the hub and axle. If it’s noisy or has play, book it in promptly and avoid long highway runs until sorted.

Do Tribeca wheel bearings need greasing during a service?

No. The 2013 Tribeca uses sealed hub-unit bearings that aren’t serviceable. Routine servicing is about inspection—listening for noise, checking for play, and looking over the ABS lead. When worn, replace the complete hub assembly.
