The invention discloses a front axle assembly, a steering axle and a vehicle, and belongs to the technical field of automobiles, and the front axle assembly comprises a front axle, a steering knuckle, a rolling-stopping integrated bearing, a main pin and a first blanking cap. The steering knuckle comprises a first fork body and a second fork body which are oppositely arranged in a spaced mode, and the first end of the front shaft is located between the first fork body and the second fork body. The rolling-stopping integrated bearing comprises an outer shell partially and coaxially installed in the second connecting hole, a containing cavity with openings in the two ends is formed in the outer shell, a needle bearing and a thrust bearing are coaxially arranged in the containing cavity, the needle bearing is located on the second fork body, and the thrust bearing is located between the front shaft and the second fork body. A dustproof sealing structure is arranged between the outer shell and the thrust bearing; the main pin sequentially penetrates through the first fork body, the front shaft, the thrust bearing and the needle bearing, and an inner sealing ring abutting against the main pin in a sealed mode is arranged on the inner side face of the thrust bearing. The first blanking cap abuts against the end face, located in the second connecting hole, of the outer shell in a sealed mode. The maintenance cost of the whole vehicle can be reduced.
