There is disclosed an independent suspension unit for a vehicle which does not require an axle. The suspension unit includes a hanger for mounting to the vehicle's frame. A control arm is provided which has opposite first and second ends, the control arm being pivotally mounted to the hanger at a pivot point positioned between the first and second ends of the control arm. The suspension unit further includes a spindle arm mounted to the first end of the control arm, the spindle arm configured to mount to the wheel. The suspension unit also includes a jounce spring made of an elastomeric polymer material mounted between the control arm and the hanger at a first point on the control arm positioned between the pivot point and the first end. The suspension unit also includes a rebound spring made of an elastomeric polymer material mounted between the control arm and the hanger at a second point of the control arm adjacent the second end. The control arm and hanger are configured such that when the first end of the control arm pivots towards the frame of the vehicle the jounce spring is compressed and the rebound spring is relaxed. The control arm and the hanger are further configured such that when the first end of the control arm moves away from the frame the jounce spring is relaxed and the rebound spring is compressed.
