Patent number: 7331589Abstract: 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.Type: GrantFiled: March 20, 2007Date of Patent: February 19, 2008Assignee: Stempf Automotive Industries, Inc.Inventors: William E.

Patent number: 6131883Abstract: A pry tool for facilitating disassembly of suspension components in a vehicle wheel suspension assembly which includes a vehicular telescopic strut member secured to a steering knuckle. The tool comprises a handle member along with a fulcrum tower, with the combination being arranged to substantially enclose the strut, and through forces created by the pry tool, and against the coil spring, the tool enables and facilitates removal of the steering knuckle from the body of the strut. The pry tool includes an elongated handle with a handle yoke at one end for enclosing or enveloping the strut, and with a fulcrum yoke at the opposed end for contacting the upper end of the steering knuckle. Axial removal forces are applied between the coil spring and the steering knuckle, thereby freeing the strut component from the assembly.Type: GrantFiled: August 18, 1999Date of Patent: October 17, 2000Assignee: Northstar Manufacturing Co., Inc.Inventors: Thomas G. Spears, James R. Ryshavy
