A suspension system can include a spring beam with a bushing receiving opening having outer ends with larger dimensions as compared to an intermediate section of the opening. Another suspension system can include a spring beam having a bushing receiving opening, a resilient bushing received in the opening, and a rigid sleeve received in the bushing, a radial distance between the sleeve and the opening being reduced between opposite ends of the opening. Another suspension system can include an axle, a spring beam attached to the axle, the spring beam including a bushing receiving opening, and a resilient bushing received in the opening, the bushing having outer ends with larger outer dimensions as compared to an intermediate section of the bushing between the bushing outer ends.
