Parts for your 2013 Subaru Tribeca-Wheel bearings

2013 Subaru Tribeca wheel-bearings: purpose, care and when to replace

Technical references including the Subaru Service Manual for MY2013 Tribeca (Chassis – Front/Rear Axle, Wheel Hub sections), the Subaru Genuine Parts Catalogue, and major aftermarket catalogues (SKF, NTN/NSK, Timken) confirm that the 2013 Subaru Tribeca uses sealed, bolt-in wheel hub and bearing assemblies on all four corners. So wheel-bearings are absolutely relevant and fitted to this vehicle.

On the Tribeca, the wheel-bearings are a sealed, unitised hub assembly. Their job is to let each wheel spin smoothly while carrying the vehicle’s weight, keeping the wheel precisely located to the knuckle, and maintaining correct ABS signal via the integrated encoder ring. Being sealed-for-life units, they don’t need periodic greasing, instead, good servicing is about regular inspection, correct torqueing of wheel nuts, and timely replacement when wear shows up.

Typical service advice for a 2013 Subaru Tribeca wheel-bearings setup is to check for noise and play at each scheduled service (every 10,000–15,000 km is a sensible interval). Technicians will spin the wheel, feel for roughness, and check for looseness at the 12 and 6 o’clock positions. Because this is an AWD Subaru, keeping tyre sizes matched and wheel nuts torqued to spec helps avoid extra load on the bearings.

• Telltale signs: a humming or growling that rises with road speed, a droning tone that changes on gentle lane sweeps, ABS warning from a damaged encoder, uneven tyre wear, or heat at the hub after a drive.
• Service tips: avoid hard kerb strikes and high-pressure water directly at the hub, torque wheel nuts correctly, and check alignment after any bearing or suspension work.

Replacement on a Tribeca is straightforward for a pro: the hub/bearing unbolts from the knuckle and is replaced as a complete assembly. It’s best practice to use new mounting bolts and a new axle nut, clean the mating surfaces, and protect the nearby ABS sensor. A road test and ABS scan check are smart finishing steps. There’s no set replacement interval—lifespan depends on roads and loads—but many last well past 120,000–180,000 km. Bearings can be replaced individually, changing both on the same axle isn’t mandatory, though if one has failed due to water or impact, assessing the opposite side is wise.

• Popular questions about 2013 Subaru Tribeca wheel-bearings

How long do wheel-bearings last on a 2013 Subaru Tribeca?
The sealed hub units often run 120,000–180,000 km or more, provided wheels are torqued correctly and tyres are matched. Harsh roads, heavy loads, or water ingress can shorten life.

Should both front or both rear wheel-bearings be replaced together?
It’s fine to replace just the noisy or loose side. However, if one failed due to impact or immersion, the mate on that axle should be carefully checked and may be replaced preventatively.

What noise points to a failing Tribeca wheel-bearing?
Listen for a steady rumble or growl that increases with speed and often changes when gently steering left or right. Tyre roar can sound similar, so a proper workshop road test and lift inspection helps confirm the source.
