Dual axis bushing assembly and method for camber and caster adjustment

Abstract

A dual axis bushing assembly for engagement between an axle arm and an upper ball joint of a vehicle. The dual axis bushing assembly includes an inner skewed bushing engaged in and rotatable in an outer skewed bushing. The dual axis bushing assembly includes a zero offset setting or a zero skewed setting where a skewed axis of the inner bushing is coaxial with a center axis of an outer cylindrical surface of the outer bushing. At the zero setting, a connector seating annular surface on the inner skewed bushing is disposed at a right angle relative to a cylindrical outer surface of the outer skewed bushing. In one embodiment, the connector seating annular surface is recessed in a head of the inner skewed bushing. In another embodiment, the connector seating annular surface is an outermost end surface of a head of the inner skewed bushing. A method of camber and caster adjustment is disclosed that eliminates each of the steps of installing a standard zero bushing, taking camber and caster readings with the standard zero bushing in place, and then removing the standard zero bushing for an after market bushing.
