Parts for your 2009 Subaru Forester-Wheel bearings

2009 Subaru Forester Wheel Bearings

Wheel bearings absolutely are used on the 2009 Subaru Forester (SH). Technical sources including the Subaru Factory Service Manual for the SH chassis, the Subaru Genuine Parts Catalogue, and major bearing makers’ application guides (SKF/NTN) all specify sealed, bolt-in hub unit bearings front and rear. These assemblies support the wheel, carry cornering and braking loads, and include the ABS tone functionality, making them a key safety and drivability item.

On this Forester, each wheel runs a sealed hub bearing assembly designed to spin smoothly with minimal friction while keeping the hub rigid and the tyre contact patch steady. Because they’re sealed, there’s no scheduled greasing, instead, servicing focuses on inspection and timely replacement when wear shows up. Typical lifespan varies with use and conditions—urban commuting, rough rural roads, water crossings, and big potholes all play a role.

Owners should watch (and listen) for classic clues:

• A steady humming or growl that rises with speed and often changes when gently weaving left–right.
• Fine vibration through the cabin or steering at highway pace.
• ABS warning or erratic ABS behaviour if the bearing’s encoder is affected.
• Excess play when rocking the wheel at 12 and 6 o’clock during a service check.

Routine servicing is simple: during tyre rotations or brake work, spin each wheel, feel for roughness, and check for free play. After a long drive, a noticeably hotter hub (compared side to side) can also hint at a failing bearing. Catching issues early helps avoid collateral damage to the hub or knuckle.

Replacement on the 2009 Forester is a straightforward bolt-off/bolt-on job for a competent technician: remove the wheel, caliper and rotor, unplug the ABS lead, undo the axle nut, then the four hub bolts from the back of the knuckle, and withdraw the hub. Corrosion can seize the unit in place, so penetrating oil and a puller are common tactics. Refit with a quality hub assembly, new hardware where specified, and tighten everything to the Subaru FSM torque specs. Protect the ABS lead, confirm smooth rotation, and road-test for quiet operation. An alignment check is wise if any suspension fasteners were disturbed.

Following the factory guidance from the Subaru FSM and trusted parts catalogues keeps this Forester rolling quietly, safely, and without nasty surprises.

Popular questions about 2009 Subaru Forester wheel bearings

How can someone tell which wheel bearing is noisy?
Most times, the noise gets louder with road speed and changes when gently steering side to side—load on the noisy side makes the hum more pronounced. A workshop can confirm with a road test, chassis ears, and by checking for roughness and play with the car safely raised.

Does the 2009 Forester need a press for bearing replacement?
No. This model uses a sealed, bolt-in hub unit, so there’s no pressing in and out of separate bearings. The old hub is unbolted from the knuckle and a complete new hub assembly is installed, then torqued to the Subaru FSM specifications.

Should both front or both rear bearings be replaced together?
Not necessarily. Bearings are replaced on condition. If one side fails due to age or kilometres, the opposite side may still be fine. That said, many owners opt to replace pairs if the vehicle has high kilometres or similar wear history for peace of mind.
