SKF BR931103 rear wheel bearing and hub assembly for the 2015-2021 Subaru Outback and other vehicles supports the rear wheel and lets it spin on the axle.
A hum or growl that rises with road speed can mean a worn wheel bearing and hub assembly. Those signs alone do not prove the hub is at fault, since uneven tire wear can make a similar drone.
This SKF wheel bearing and hub assembly is a direct-fit replacement for the 2015-2021 Subaru Outback, the 2015-2021 Subaru Legacy and the 2019-2021 Subaru Ascent. Plan on replacing the rear pair together. This listing is a single hub, and the rear of these Subarus takes two.
