Vehicle Wheel Axle Assembly

A vehicle wheel axle assembly having: an axle sleeve with first and second end faces and an axial opening having a radially inwardly projecting first engagement surface; and a control shaft with a radially outwardly projecting second engagement surface. The control shaft is axially retained to the axle sleeve by an overlie engagement at an engagement interface between the first and second engagement surfaces to limit the axial displacement of the control shaft in a retracting direction relative to the axle sleeve. At least one of: the first engagement surface is in an engagement element discreet from and axially retained to the axle sleeve such that the engagement element may be installed and/or removed to/from the axle sleeve; and the second engagement surface is in an engagement element discreet from and axially retained to the control shaft such that the engagement element may be installed and/or removed to/from the control shaft.
