Suspension unit having camber and/or toe adjustment mechanism for suspending a wheel and tire assembly from a vehicle frame

A suspension unit for suspending a wheel and tire assembly from a vehicle frame includes a hanger, a control arm, a spindle assembly, a jounce spring, a rebound spring, a camber adjustment mechanism, and a toe adjustment mechanism. The spindle assembly is connected to an upper wall top surface of the control arm at an upper wall terminal end. The jounce spring is positioned between the upper wall top surface and a top wall bottom surface of the hanger. The rebound spring is positioned between a forward wall outer surface of the control arm and a front wall inner surface of the hanger. A mounting bolt connects the control arm to the hanger. The camber adjustment mechanism is configured to change a first position of a mounting bolt first end of the mounting bolt along a y-axis relative to a second position of a mounting bolt second end along the y-axis. The toe adjustment mechanism is configured to change a third position of the mounting bolt first end or the mounting bolt second end along an x-axis relative to a fourth position of an opposing mounting bolt end along the x-axis.
