The drive axle assembly includes a wheel bearing assembled with a wheel housing, an outer ring having a ring shape and including an outer-diameter portion secured to an outer wheel of a wheel bearing, a boot including a large-diameter portion formed at one end thereof and assembled with an inner-diameter portion of the outer ring, and a bearing seal unit disposed between a small-diameter portion formed at the other end of the boot and a drive shaft to restrict rotation of the boot and to prevent introduction of foreign substances.
