Parts for your 2006 Subaru Forester-Wheel bearings

2006 Subaru Forester wheelbearings — what they do and when to replace them

Wheelbearings are absolutely fitted to the 2006 Subaru Forester, front and rear. This is confirmed by the Subaru Forester (SG) Service Manual for 2006 and Subaru Technical Service Bulletin 03-50-02R, which details the revised tapered-roller rear bearing kit used to address earlier premature wear. Those technical sources make it clear the 2006 Forester relies on sealed wheelbearings as a core part of the hub and knuckle assembly.

On this model, wheelbearings let the wheels spin smoothly while carrying vehicle weight and cornering loads, keeping the hub precisely aligned with the brake and ABS hardware. The fronts use a press-in, double-row angular-contact ball bearing with a separate hub, the rears on many vehicles are serviced with an updated tapered-roller style bearing. All are sealed-for-life units, so there’s no routine greasing—when they wear, they’re replaced.

As part of regular servicing on a 2006subaruforester, the workshop will check for bearing play and roughness, spin each wheel off the ground, and listen on-road for a speed-dependent hum that often shifts when loading the car left or right. Any grumble, notchiness, or heat at the hub points to a tired wheelbearing. Subaru’s bulletins note that water crossings, corrugated roads, oversized wheels, and hard knocks can hasten wear, so Foresters that see plenty of Kiwi or Aussie backroads deserve closer attention.

• Typical symptoms: a low droning that grows with speed, a cyclic growl in corners, ABS pulsation without brake input, uneven tyre wear, or measurable wheel play.
• Inspection tips: chock safely, lift and spin by hand, feel for roughness, and check for axial/radial movement, use a mechanic’s stethoscope on the knuckle if needed.

Replacement on a 2006subaruforester wheelbearings job is straightforward but precise. Use quality OEM or reputable bearings, renew seals and circlips, keep the ABS sensor spotless, and press via the outer race only to avoid damage. The axle nut should be replaced and correctly torqued then staked per the service manual—no rattle-gun guessing. A quick alignment check after rear bearing work is smart, especially if suspension bolts were disturbed. It’s not mandatory to change both sides, but if one rear bearing has failed and the opposite side has similar kilometres and use, many owners choose to do the pair to save downtime.

There’s no fixed replacement interval, many last 120,000–200,000 km or more, but once noise or play appears, timely replacement protects tyres, brakes, and hubs. With the right parts and procedures—as laid out in the Subaru Service Manual and the wheelbearing update TSB—the Forester stays quiet, safe, and ready for the next road trip.

• Popular questions about 2006subaruforester wheelbearings

How long do wheelbearings typically last on a 2006 Subaru Forester?

Many see 120,000–200,000 km, but lifespan varies with road conditions, wheel/tyre setup, and driving style. Vehicles spending time on rough, wet, or dusty roads may need them earlier.

At each service, a quick check for noise and play is the best way to catch issues before they chew out tyres or stress the hub and ABS hardware.

What does a failing wheelbearing sound like, and how can it be confirmed?

Usually a steady hum or growl that rises with speed and often gets louder when loading that corner (gentle lane changes). It doesn’t change with engine rpm.

A road test plus a hoist check—spinning the wheel, feeling for roughness, and listening at the knuckle—will confirm it. Some shops use chassis ears to pinpoint the noisy side.

Do both rear wheelbearings need replacing together?

Not strictly. If only one is noisy and the other is tight and quiet, replace the faulty one. That said, if they’ve done similar kilometres and duty, owners sometimes do both to minimise repeat trips.

Either way, use the updated tapered-roller style rear bearing where applicable, follow factory torque-and-stake steps, and keep the ABS sensor clean.
