The front axle has a steel structure with a double “T” section having at the end steering knuckles.
The steering knuckles’ connection is made through pins integral with the axle body and by means of four roller bearings set with
interference in the holes of the steering knuckles’ embossing.
The wheel hubs are supported by two conical roller bearings set on the steering knuckle shank and adjustable by a threaded ring.
