A wear bushing assembly (20) protects and locks down a hanger (46) in a wellhead housing (45), and includes a wear bushing body (22) that inserts into a wear bushing sleeve (34). A lock ring (40) extends into registered recesses (42, 44) on the body and sleeve to couple together the body and sleeve. The wellhead housing has a profiled recess circumscribing its inner surface. A lockdown ring (28) selectively mates with the profiled recess; and when mated is in interfering contact with an upper surface of the wear bushing sleeve, thereby coupling the sleeve to the wellhead housing. The sleeve outer surface is profiled to interfere with upward movement of the hanger, so that force is transferred from the hanger to the housing through the sleeve which locks down the housing.
