Abstract: An axle assembly is provided having a varying wall thickness resulting in an axle assembly that is lightweight yet has sufficient strength and stiffness. The axle assembly includes a tube disposed about a longitudinal axis and having first and second end portions and a center portion. The first and second end portions have a uniform wall thickness and the center portion has a wall thickness that is uniform at first and second axially spaced segments and a non-uniform wall thickness both between the axially spaced segments and between each of the axially spaced segments and the end portions.

Abstract: A vehicle suspension and a control arm therefor are provided. The control arm includes first and second members each defining a recess corresponding to a portion of the outer surface of a vehicle axle. The members are welded or otherwise coupled together to surround at least a majority of the axle thereby enabling installation of the control arm without sliding the arm onto the axle. Each of the members includes a pair of sidewalls and a lateral wall joining, and integral with, the sidewalls. The sidewalls are angled relative to an axis of the axle to provide sufficient clearance for a spring assembly mounted to the control arm and centering of spring loads. The two sidewalls of one member may further include aligned apertures configured to receive a tube on which a shock absorber may be mounted. The tube enables strong and accurate mounting of the shock absorber.

Abstract: A vehicle suspension and alignment device therefor is provided. The suspension includes a suspension control arm connected to an axle of the vehicle and having one end pivotally connected to a bracket extending from a frame of the vehicle. The end of the control arm is capable of rotation about a first axis extending transverse to the longitudinal direction of the vehicle. The suspension further includes a thrust washer disposed between one wall of the bracket and the end of the suspension control arm and a fastener that extends through the bracket, the washer, and the end of the suspension control arm. The washer is configured for engagement by a tool used to rotate the washer and cause movement of the suspension control arm relative to the bracket to thereby align the suspension and a vehicle axle.
