  • Patent number: 7331589
    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.

  • Patent number: 6293724
    Abstract: An adjustable ball joint assembly to be secured between the wheel and the apex of an upper control arm member of a motor vehicle suspension system to provide for camber/caster adjustment of motor vehicles with altered suspensions, typically lowered suspensions. The adjustable ball joint includes a ball joint retainer body including a locking plate and with an eccentrically positioned ball socket (opening) formed in the bottom surface of the plate. A stub shaft, fast on the top surface of the locking plate, extends upwardly, with an arcuately configured annular groove formed around its periphery. A tapered boss is positioned adjacent the top surface of the locking plate and configured to be received within the ball joint port of the control arm.

  • Patent number: 6131883
    Abstract: 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.

  • Patent number: 5104141
    Abstract: Camber adjustment assembly for adjustably and securely positioning a wheel within a vehicular suspension system utilizing a generally vertically arranged support strut with the lower end of the strut being provided with a generally "U"-shaped bracket secured fast thereupon. The bracket is typically provided with two vertically spaced apart bore pairs for receiving through-bolts therethrough, and for retaining the knuckle assembly therewithin. The camber adjustment assembly includes an eccentric bolt having an eccentric segment between the head portion and the distal portion, with the eccentric segment being designed to be retained within either the upper or lower series of bores formed in the knuckle assembly.
