The front wheels are mounted on the stub axle, which are connected to the front axle by means of king pin. The stub axles are the forging of 3 per cent nickel steel and alloy steels containing chromium and vanadium.

The stub axle turns on the pin which is a light drive fit in the axle beam eye located and locked by a taper pin or some similar arrangement.

Stub axle can have any of four shapes given in Fig

• The Elliot stub axle (i) is attached to the front axle by placing it in the yoke end with a king pin and cotter to join the two together.
• In reversed Elliot type stub axle (ii) the arrangement is reversed.
• In Lemoine type stub axle (iii) and (iv), instead of yoke type hinge, a L-shaped spindle is used.

The stub axles are pivoted on the end of the axle beam It is the spindle over which the read wheel is mounted through the break down. It gets as an axis for the wheel. It takes load of the wheel & enables it to spin around. The Stub axles are the forging of 3% nickel steel & alloy steel containing Chromium & Vanadium.
The stub axle turns on the pin which is a tight drive fit in the axle beam eye located & locked by a tapper pin or some similar arrangement.
Stub axle can have any of four shapes given in fig 18.1.
i) The Elliot stub axle is attached to the front axle by placing it in the yoke end with a King pin & cotiler to join the two together (fig:18.1(a)).
ii) In reverse Elliot type stub axle, the arrangement is reverse (fig:18.1(b)).
(iii) In Lemoine type stub axle (fig:18.1( c) & (d)), instead of yoke type hinge, a l-shaped spindle is used.
