A vehicle suspension system includes a wishbone-shaped linkage (44) having a base (46), with two limbs (48) extending from the base (46). Each limb (48) is configured to support a laterally and longitudinally oriented bushing assembly (52), which may include a bushing assembly received by a laterally and longitudinally oriented mounting tube associated with a free end of the limb (48). The base (46) includes upper and lower plates (72, 74) wrapping only partially around a laterally extending cross tube (68). A modular bushing assembly including a pair of bushing lobes and a bar pin is partially received within the cross tube, with the bushing lobes being adjustably positioned on the bar pin to allow for adjustment of the conical rate of the bushing assembly. A mounting assembly includes a pair of mount blocks secured to a vehicle axle, with the bar pin being secured with respect to the axle via the mount blocks, thereby associating the linkage to the axle.
