King Pin Kit with OEM number 40025-NA01J (40025NA01J) is a verified direct-fit steering repair set designed for NISSAN UD MK210 trucks and compatible NISSAN UD Condor chassis. This king pin kit serves as the critical pivot assembly connecting the steering knuckle to the front axle beam, enabling controlled and precise steering movement across the full range of vehicle operation.
The king pin functions as the central pivot of the steering system. When the steering wheel is turned, the king pin allows the steering knuckle — and therefore the wheel — to rotate smoothly around a vertical axis. A worn or damaged king pin directly compromises steering precision, tire wear patterns, and overall vehicle safety.
