Complete Guide to Full Set Front Rear Wheel Hub Bearings AWD for Subaru Forester Impreza 2009-2013

If your 2009-2013 Subaru Forester or Impreza starts humming somewhere around 40-50 mph and the noise climbs with speed, a worn wheel bearing is the usual suspect. On an AWD car, when one bearing fails the other three are rarely far behind — which is the whole argument for the Full Set Front Rear Wheel Hub Bearings AWD For Subaru Forester Impreza 2009-2013.

This guide covers what the kit includes, why AWD Subarus are harder on bearings, the five failure symptoms to watch for, and the installation details that decide whether your new bearings last. Every spec and number below comes from the product data and automotive service references behind it.

The short version

• 4 pieces: both front and both rear wheel hub bearings.
• Fits 2009-2013 Subaru Forester and Impreza, AWD models.
• G3 (third generation) units, brand new, direct replacement.
• Built to meet or exceed OEM specifications for Subaru's symmetrical AWD system.

What the Set Includes

The kit covers all four corners in one order: two front wheel hub bearings and two rear wheel hub bearings. You are not sourcing parts piecemeal, and you are not mixing bearing generations on the same car — a real risk when you fix one corner now and another corner eight months later.

Each unit is a brand-new direct replacement that installs in the stock location with no modifications. The full specification:

Why AWD Subarus Work Their Bearings Harder

Wheel hub bearings carry the vehicle's weight while letting each wheel spin freely. In a two-wheel-drive car, only two bearings ever see drive torque. In your Subaru's symmetrical AWD system, all four bearings handle torque distribution forces that never stop changing, on top of load and cornering stress.

The Full Set Front Rear Wheel Hub Bearings AWD is engineered for exactly that duty: proper load distribution and rotational stability across all four wheels, not a part that was merely close enough for the application.

Five Symptoms of a Failing Wheel Bearing

Catch a bearing early and you protect the hub, the sensor, and the tire. Automotive service data points to five warning signs, in rough order of how often they show up:

1. Humming or growling noise. The most prevalent symptom, and it typically increases with vehicle speed.
2. Vibration. Noticeable in the steering wheel or through the vehicle floor.
3. Wheel wobble. A wobble you can see or feel while driving.
4. Uneven tire wear. Abnormal wear patterns caused by improper wheel alignment at the hub.
5. ABS warning light. Failing bearings can trigger ABS system warnings in some cases.

Why Replace All Four Instead of Just the Noisy One

Replacing only the bearing that is making noise feels frugal. The service math says otherwise:

• Uniform wear. All four bearings start even and wear at the same rate, giving you one predictable service schedule.
• Cost efficiency. A complete set is often more economical than individual bearings bought separately, corner by corner.
• Time savings. One service session covers the whole car.
• Performance consistency. Balanced bearings maintain consistent AWD performance at all four corners.
• Preventive maintenance. You deal with the three future failures now, while the wheels are already off.

Installation Notes That Decide Bearing Life

A premium bearing can be ruined in the first ten minutes by a careless install. The service guidance is short and specific:

• Use proper torque specifications — an over-torqued axle nut preloads the bearing and kills it early.
• Work clean. Contamination is the enemy of a precision bearing.
• Follow manufacturer-recommended procedures, not shortcuts.
• Consider professional installation for optimal results.
• Always replace the axle nuts with new ones during bearing replacement.

This is a direct-replacement job in the stock locations. If you have done hub bearings before and own a torque wrench, it is within DIY territory. If not, pay for the professional install — the parts cost is the same either way, and bearing life depends on the workmanship.

Two Parts Worth Checking in the Same Service Window

While the wheels are off, these two items share the same corner of the car as the bearings:

• Front ABS wheel speed sensors. Because failing bearings can trigger ABS warnings, the sensors belong in the same diagnosis. If the sensors turn out to be the culprit, the 2Pcs ABS Wheel Speed Sensor Front Right & Left kit for Subaru Impreza, Forester and WRX covers both front corners.
• Single rear bearings for other Subarus. Also running a Legacy, Outback, or BRZ — or you only need one rear corner? The 1Pc Wheel Hub Bearing Rear AWD for Subaru Forester, Legacy, Outback, Impreza and BRZ is the single-piece option.

For the rest of that corner of the car — wheels, tires, hubs, hardware — the Wheels, Tires & Parts collection is the full Koeep catalog.

And if you are changing wheel fitment during the same job, read the guide to 2X 1 Inch Thick Wheel Spacers 5x100 12x1.25 for Subaru Impreza, Forester and Outback before you order spacers.
