The invention relates to the technical field of automobile axles, and provides a front axle assembly and a vehicle. The front axle assembly comprises a main pin, a front beam, a steering knuckle, a first bearing, a second bearing, a first grease outlet assembly and a second grease outlet assembly. The main pin is fixedly connected with the front beam and hinged to the steering knuckle. The first grease outlet assembly is installed on the first grease outlet channel, and the first grease outlet assembly is used for opening the first grease outlet channel to discharge lubricating grease when the grease injection pressure reaches a preset value and blocking the first grease outlet channel to achieve sealing after grease injection is finished; the second grease outlet assembly is provided with a second grease outlet channel; a stepped hole is formed in the area, located at the second end of the main pin, of the steering knuckle; the stepped end of the second grease outlet assembly is hermetically connected with the stepped hole; the second grease outlet channel is provided with a one-way concentric-square-shaped sealing structure so that one-way grease outlet of the lubricating grease can be achieved. According to the front axle assembly, effective grease injection and sufficient lubrication of the master pin can be achieved, the sealing performance can be ensured, and the service life of the master pin is prolonged.
