Abstract: A method of controlling caster and/or camber angle by controlling the amount of heat input during the welding process associated with the axle tube brackets and other suspension components such as the lower control arm, spring seat, shock bracket and sway arm bracket. In other words, larger hot weld spots versus smaller cooler welds will distort the axle tube differently. If the design of a tube assembly has undesirable caster and/or camber angles due to distortions caused by the welding of suspension components, the weld can be tuned to distort the assembly to a desired caster and/or camber angle. For example, if the camber desired requires the axle tube to be deflected up, the travel speed of welds on the top side of the tube may be slowed thus increasing the heat input.
