KNUCKLE (Komatsu KO3EA2413221)

A worn knuckle can compromise steering response and lead to uneven tire wear. This aftermarket replacement part references the Komatsu catalog and carries the cross-reference number KO3EA2413221. The knuckle serves as a pivot point in the steering linkage, converting rotational input from the tie rod into angular movement of the wheel assembly. Over time, a knuckle with excessive play or corrosion may cause vague steering feel and reduced directional stability. During routine inspection, check the knuckle for cracks, deformation, or seized pivot points. Verify the serial number or application, then call (562) 693-7748. A properly functioning knuckle helps maintain consistent steering geometry under load.
