A trunnion mount single point vehicle suspension including a load monitoring apparatus. The suspension includes a trunnion shaft, means for attaching the shaft to a vehicle frame and an axle spring assembly mounted to the trunnion shaft and spaced from the attachment means. It also includes strain measuring means mounted in the trunnion shaft between the attaching means and the axle spring assembly for measuring changes in the shaft. In one embodiment the means for attaching the trunnion shaft to the vehicle frame is a trunnion hanger mounted inboard of the axle spring assembly. In another embodiment the attaching means is a clevis bracket which straddles the axle spring assembly. Also disclosed is a load monitoring apparatus for measuring the weight imposed by the trailer at its mounting point on the tractor. The apparatus includes at least one pin load cell having spaced shear strain measuring means and trailer mounting means attached to the pin cell intermediate the shear strain measuring means.
