Stub Axle: Stub axles are attached to the vehicle's front wheels, with kingpins connecting these axles to the front axle.
As The Engineers Post explains, there are four types of stub axle:
Elliot: This type uses a kingpin, a yoke, and a cotter to connect to the front axle.
Reverse Elliot: This type has the opposite arrangement of a standard Elliot stub axle.
Lamoine: This stub axle type has an L-shaped spindle instead of a yoke-type hinge.
Reverse Lamoine: It has the opposite layout of a standard Lamoine stub axle.
