A wheel-end assembly is described which includes a hub (100) and a planetary gear system (110). The planetary gear system (110) includes a sun gear (120), planetary gears (130), and an outer gear (140). The planetary gear system (110) is arranged so that drive provided by a shaft (160) is transmitted by the outer gear (140) to a wheel on the hub (100). A planetary gear carrier (150) attached to a shaft casing (170) remains stationary. The arrangement of the gears allows a breaking mechanism (195, 200) to be positioned out-board of the planetary gear system.
