A vehicle suspension system (11) provides a flexible connection between a vehicle chassis (13) and at least one rear axle housing (15), the vehicle suspension system (11) includes three longitudinal link members (17), at least one transverse link member (19), and at least two resilient members (21) situated adjacent each end of the axle housing (15), all of which are connected at one end to the vehicle chassis (13) and at an opposite end to the axle housing (15); the transverse link member (19) is configured to substantially prevent movement of the axle housing (115) in a transverse direction; and the three longitudinal link members (17) are each substantially aligned with the longitudinal axis of the chassis (13) and are spaced apart to provide a three point connection between the chassis (13) and the axle housing (15), which is configured to keep the axle housing (15) in a substantially transverse orientation relative to the chassis (13) and to prevent rotation of the axle housing ( 15) about its longitudinal axis, while still allowing movement of the axle housing ( 15) in the vertical plane; and movement of each end of the axle housing (15) in the vertical plane is limited by the resilient members (21) which connect each end of the axle (15) to the chassis (13), at each end of the axle housing (15), at least one resilient member (21) is connected to the axle housing (15) and the other resilient member (21) is connected to the other side of the axle housing (15) and the connection of the resilient members (21) to the axle housings (15) is situated near or adjacent the lowest point of the axle housings (15) in the vicinity of the connection. In this way the longitudinal links (17) provide a three point triangular linkage system between the axle housing (15) and the chassis (13), allowing vertical movement of the axle housing (15), while restricting rotation of the axle housing (15) about its own axis and about a vertical axis.
