Abstract: A kingpin removal system including a cart assembly having one or more wheels and a yoke assembly carried by the cart assembly and positionable around a steering spindle of a vehicle's wheel end assembly. The yoke assembly can include a pair of plates interconnected by a pair of rods. An intermediate plate is positioned between the pair of yoke plates. A wheel end support mechanism can be carried by the cart assembly and a hub mounting ring can be carried by the wheel end support mechanism. The hub mounting ring can be positioned to connect to and support the wheel end assembly once the kingpin is removed.

Abstract: Technology is provided for a double wishbone independent trailer suspension. The suspension includes a slider frame configured for attachment to a semi-trailer. The slider frame includes a longitudinal central beam and upper and lower clevis brackets located on opposite sides of the central beam. A pair of upper wishbones are attached to the upper clevis brackets and at least one air spring is positioned between the slider frame and each upper wishbone. A pair of lower wishbones are attached to the lower clevis brackets and a pair of spindles are each pivotably attached to a corresponding upper wishbone and a corresponding lower wishbone.

Abstract: Technology is provided for a pneumatic anti-roll system for use on a vehicle suspension. The pneumatic anti-roll system includes left and right side air springs connectable between a chassis of the vehicle and an axle of the vehicle suspension. Left and right side height control valves are mounted to the chassis and left and right side linkages connect between the left and right side height control valves and corresponding left and right end portions of the axle. Left and right side control air lines connect between the left and right side height control valves and corresponding left and right side air springs, respectively.
