A wheel unit for a vehicle includes a main housing configured to be coupled to a chassis of the vehicle, the main housing including first and second control arms. A transmission housing includes a body having first and second protrusions extending from the body, the first protrusion partially defining a first cavity that receives a portion of the first control arm, and the second protrusion partially defining a second cavity that receives a portion of the second control arm. A first pin is coupled between the first protrusion of the transmission housing and the first control arm of the main housing. A second pin is coupled between the second protrusion of the transmission housing and the second control arm of the main housing, the first and second pins defining a steering axis. The transmission housing is pivotably coupled to the main housing about the steering axis.
