A new and improved kingpin housing assembly operatively coupling the wheel mounting assembly, the front axle and the steering assembly with the help of kingpin. The kingpin housing assembly is provided with upper and lower arm supports. The lower arm support provides a new and improved locking mechanism to keep the kingpin in place. For the kingpin housing assembly to function efficiently, the kingpin used to couple the wheel mounting assembly to the front axle must always be securely held in place to prevent wear and tear during road shocks and rapid steering maneuvers. The kingpin is held in place with the help of a locking cap received into the lower arm support and locked in place with the help of a nut and bolt combination. The lower arm support is provided with castellations along the bottom circumference. A horizontal bore is provided in the locking cap across its diameter. Once the horizontal bore and the notches formed by the castellations are aligned, the nut and bolt combination is passed there through to prevent the locking cap screw from becoming displaced from the adjusted position and thereby securely holding the kingpin in place.
