Dual Axis Bushing Assembly And Method For Camber And Caster Adjustment
US Patent:
7331589, Feb 19, 2008
Filed:
Mar 20, 2007
Appl. No.:
11/688291

Assignee:
Stempf Automotive Industries, Inc. - Minnetonka MN
International Classification:
B62D 17/00
US Classification:
280 86756
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.

B60G 15/00
US Classification:
280124155, 280124147
Abstract:
A suspension height modification apparatus includes a first portion that is securable to a vehicular biasing suspension device and a second portion that is securable to a vehicular frame. The apparatus includes an axis along which a suspension height may be determined between the vehicular frame and the vehicular wheel assembly. The apparatus may be selectively extensible along such axis.

International Classification:
B60G 11/00
US Classification:
280124175
Abstract:
A vehicle suspension lift kit includes a first suspension lift component having a first interlocking pattern, and a second suspension lift component having a second interlocking pattern. The first and second interlocking patterns are selectively matingly engagable with one another to prevent relative motion among the first and second components along an interfacial plane. Each of the first and second suspension lift components are specifically configured to be employed individually or in combination between a vehicular leaf spring suspension and a vehicular axle housing to provide a selected extent of suspension lift.
