Parts for your 2013 Subaru Forester-Wheel hubs

2013 Subaru Forester wheel hubs

Per the Subaru Factory Service Manual for the 2009–2013 Forester (SH) platform (Wheel Hub, Drive Shaft and ABS sections), the Subaru Global Parts Catalogue, and aftermarket technical catalogues from Timken and SKF, the 2013 Subaru Forester is fitted with bolt‑in wheel hub assemblies that incorporate sealed bearings front and rear. Wheel hubs are therefore absolutely relevant to this model.

The Forester’s wheel hubs do the heavy lifting: they locate the wheels, carry the vehicle’s weight through the sealed bearing, provide the wheel studs for the nuts, and deliver clean wheel speed signals for the ABS/ESC via the integrated tone ring or encoder. On an AWD Subaru, keeping hubs in top nick also helps protect CV joints and tyres by maintaining true rotation and correct geometry.

Because the bearings are sealed, there’s no greasing to do. Servicing is about inspection and replacement when wear shows up. During routine services or tyre rotations, it’s smart to check for roughness and play: spin each wheel by hand, listen for a growl, and gently rock at 12 and 6 o’clock for movement. Any rumble, notchiness, or free play means the hub assembly should be replaced. A road test for a speed‑dependent hum that changes when cornering is another dead‑giveaway.

• Common clues a hub is on the way out:
  • Humming or droning that gets louder with speed
  • ABS light or intermittent traction control intervention
  • Heat at the wheel after a drive, or uneven tyre wear
  • Wheel wobble or vibration not fixed by balancing

Replacement on the 2013 Forester typically involves removing the brake caliper and rotor, disconnecting the ABS sensor/lead, freeing the axle from the hub, then unbolting the hub unit from the knuckle. On high‑kilometre cars, corrosion can make the hub stubborn, a hub puller and penetrating oil save a lot of grief. The assembly is non‑serviceable, so it’s a straight swap—fit a quality hub unit, clean the knuckle’s mating face, route the ABS lead correctly, use a new axle nut, and torque all fasteners to the Subaru FSM specifications. After refitting, road‑test for noise, confirm there are no ABS warnings, and recheck wheel‑nut torque after 50–100 km.

As a rule of thumb, inspect hubs every 20,000–30,000 km or at each tyre rotation. Many Forester hubs run well past 150,000 km, but rough roads, big potholes, and oversized wheels can bring the date forward. Quality parts and correct torque make the biggest difference to longevity.

Popular questions about 2013 Subaru Forester wheel hubs

1) What are the signs a 2013 Forester wheel hub is failing?

Owners often notice a humming or droning that rises with speed and may change when loading the car in a corner. There can also be a faint vibration that balancing won’t fix.

Other signs include ABS or traction control lights due to a dodgy encoder signal, warmth at the hub after a drive, and detectable play when the wheel is rocked at the rim.

2) Can just the bearing be replaced, or does the whole hub need swapping?

On the 2013 Forester, the bearing is integrated into a sealed hub unit. It’s designed as a bolt‑in assembly, so the practical repair is to replace the complete hub.

This approach restores the bearing, wheel studs, and encoder together, avoids press work, and reduces the risk of damaging the new bearing during installation.

3) How long do wheel hubs usually last on this model?

Plenty of Foresters see 120,000–200,000 km on original hubs, especially with factory‑size wheels and regular servicing. Driving conditions and impacts make a big difference.

If the car does frequent gravel or hits potholes, expect earlier wear. Regular checks during tyre rotations help catch issues before they turn into bigger bills.
