Parts for your 2009 Subaru Forester-Wheel hubs

2009 Subaru Forester wheel hubs: purpose, care and when to replace

Wheel hubs are very much used on the 2009 Subaru Forester. Technical sources confirm this fitment: the Subaru Factory Service Manual for the 2009 Forester SH (Chassis/Wheel & Axle sections) specifies bolt-in hub unit bearings front and rear, the Subaru genuine parts catalogue lists front and rear hub unit assemblies for this model, and major bearing catalogues (e.g., Timken’s listings commonly referenced in workshops) show complete hub units for the 2009 Forester (front and rear). Part numbers can vary by VIN and market, but the design is a sealed hub-and-bearing assembly with wheel studs and an integrated tone ring for the ABS/vehicle speed signal.

On the 2009 Forester, the wheel hub’s job is to carry the wheel and tyre, house the sealed bearing, and provide a mounting point to the knuckle or trailing arm. It keeps everything spinning smoothly, holds the rotor in place, and sends accurate wheel-speed info to the ABS and stability systems. Being a sealed unit, it doesn’t need routine greasing, which makes life easy, but when it wears, the whole assembly is replaced.

Typical signs it’s time for new hubs include a humming or growling noise that rises with road speed, a droning that changes when turning slightly, ABS or traction lights popping up, or a faint vibration through the seat or steering. If there’s play when rocking the wheel at 12 and 6 o’clock, that’s another giveaway. Left too long, a tired hub can scallop tyres and mess with braking feel.

• Service pointers for a 2009 Forester hub job:
  • Confirm the noisy corner with a proper road test and on-hoist check, don’t just guess.
  • Replace the hub assembly rather than trying to service the bearing — it’s a sealed unit.
  • Use a new axle nut and torque everything to factory spec, recheck axle nut preload after settling.
  • Clean rust from mating faces so the rotor runs true, a light film of anti-seize helps in coastal areas.
  • Inspect ABS wiring and connectors, a damaged pigtail can mimic a bad hub.
  • After rear hub work, a wheel alignment check is smart, especially if bolts were seized or arms disturbed.

Quality aftermarket or OE-equivalent hubs suit daily Australian and New Zealand driving, including corrugations and coastal conditions. Many workshops recommend doing hubs as needed rather than in pairs, but if one’s failed at high kilometres, the mate may not be far behind.

Popular questions about 2009 Subaru Forester wheel hubs

How can someone tell which hub is noisy on a 2009 Forester?

A steady hum that changes with speed is the classic clue. On a safe test loop, gentle lane changes can load and unload each side — noise that gets louder when loading the left often points to the right hub, and vice versa. On the hoist, a tech will spin each wheel by hand, listen with a stethoscope, and check for roughness or play at 12 and 6 o’clock to confirm the culprit.

They’ll also scan for ABS faults, a dodgy hub can set wheel-speed sensor codes if the internal tone ring or sensor path is affected.

Can just the bearing be pressed in, or is it a full hub replacement?

For the 2009 Forester SH, it’s a bolt-in hub unit. The sealed bearing is integral to the hub, so standard practice is to replace the complete assembly. This avoids press damage, restores correct preload, and keeps the ABS tone ring geometry spot on.

Older Subarus used press-in bearings, but this generation is designed for quick hub swaps and reliable sealing.

What do hub replacement costs and lifespans look like in AU/NZ?

Many see 100,000–200,000 km before a hub gets noisy, though coastal exposure, big potholes, heavy loads, or larger tyres can shorten that. For pricing, quality aftermarket hubs are often in the AUD/NZD ,150–,350 range per corner, genuine/OE can run higher. Labour is commonly about 1–2 hours for the front and 1.5–2.5 hours for the rear, depending on corrosion and seized bolts. An alignment check is a modest extra if rear links were disturbed.
