You can get new knuckles with bearings already pressed in together with hubs. Make sure to specfiy if ABS equipped since the ABS bearings have a ring, and the knuckle, a hole for the sensor.i want to replace my wheel bearings. been reading some posts, still blurry. if i get new knuckles in front do they come with bearings? also, do new drums (which i need), come with bearings, or do i need to get the hubs also (rear)?
