Axle and Knuckle Weldment
SAF-Holland

Axle and knuckle weldment comprises the welded junction that couples the steering knuckle to the axle assembly, transmitting steering input and supporting wheel loads. The component is engineered to maintain precise camber and kingpin alignment while withstanding repeated cyclic loading from steering actions, road irregularities, and braking moments. It integrates with the vehicle’s front-end geometry and bolt patterns for knuckle attachment, presenting a robust connection that resists fatigue and torsion. VMRS code 077-003-047 categorizes it within axle to knuckle weldments, aiding engineers and technicians in matching exact configurations for front-drive and steering assemblies. Category 42727 situates this part in the steering and suspension interface. The weldment enables predictable handling, consistent tire wear, and reliable steering response under heavy loads. Proper welding quality, heat treatment, and inspection are essential to prevent crack initiation. This part is critical for safety and performance in urban, regional, and long-haul fleets where front-end integrity directly influences maneuverability and operator confidence.
