Abstract: A device for adjusting at least one alignment characteristic in a suspension system of an automotive vehicle that includes a wheel support member and a wheel attached to the wheel support member by at least one removable bolt, whose removal permits the alignment characteristic of the wheel to be adjusted. The device includes an adjusting bolt means having a shaft whose diameter is smaller than the diameter of the removable bolt and a mechanism for engaging the adjusting bolt such that the adjusting bolt is axially offset in the bore from which the removable bolt was removed and a mechanism for acting against the wheel assembly due to the offset axial position of the adjusting bolt for movement of the wheel assembly relative to the wheel support and means for securing the bolt in a non-rotatable position once the adjustment of the alignment characteristic has been completed.

Abstract: A shim device adjusts camber and/or toe of a wheel assembly that is attached to an axle assembly by a plurality of spaced apart bolts. The shim device includes a relatively flat tapered plate that has a indicia selectively positioned thereon to indicate the angular position of the plate with respect to the bolts such that the plate may be selectively positioned to adjust camber and/or toe a selected amount.

Abstract: A tool for adjusting the alignment in a wheeled vehicle steering structure using a bushing includes a plate having indicia disposed around an aperture that runs through the plate wherein the indicia indicate an angular position for rotatably adjusting the bushing and including a mechaism for securing the plate to the steering structure in a selectable and fixed position and for retaining the bushing in a position during alignment.

Abstract: A device is used to adjust caster of a wheel in a suspension system that includes a rod member that affects the caster of the wheel. A portion of the rod member is disposed within a bushing that is attached to the vehicle. The device includes a curved longitudinal member for insertion between the portion of the rod member disposed within the bushing and the bushing.

Abstract: A device is used to adjust alignment of a vehicle wheel connected to a vehicle by a suspension system having an arm member affecting wheel alignment. The arm member has a first bore transversely disposed therethrough with respect to the axis of the member with the arm member being attached to the vehicle by a bolt extending through the first bore. The device displaces the bolt of the control arm from its original position to a second preselected position, thereby adjusting the alignment of the wheel.

Abstract: The present invention includes a bushing indexing tool having an aperture in its upper surface which may be reproducibly located around a rotatable caster and camber adjustment offset bushing. A scale disposed around the aperture indicates the angular position of the bushing with respect to the steering structure. The invention also includes a data base to predetermine the desired rotational angular setting of a particular bushing in order to correct caster and camber.

Abstract: A device is used to adjust toe angle of a vehicle wheel connected to a car by a suspension system having at least one control arm transversely disposed to the longitudinal axis of the vehicle. The control arm is attached to the wheel at one end and pivotally attached to an underside of the vehicle at another end by a bolt. The device displaces the bolt of the control arm from its original position, thereby adjusting the toe angle of the wheel.

Abstract: A camber and toe arrangement includes an improved shim device that adjusts both the camber and toe of a motor vehicle wheel. The shim device includes a tapered plate having a plurality of spaced apart bolt-engaging notches around the periphery. The bolt-engaging notches permit the shim device to be inserted between the wheel and the axis without removing the wheel mount and permit the shim device to be rotated so that the position of the taper is adjustable for correction of both toe and camber. The shim is inserted between the axle and the wheel mount by loosening all the bolts and removing two of the bolts, inserting the shim in the desired position and so that the remaining bolts engaging the bolt-engaging notches of the shim, inserting back the two bolts that were removed, and tightening all four bolts.

Abstract: The present invention includes a bushing having an eccentric inner bore, used for adjusting camber and caster in conventional vehicle steering structures. The bushing assembly is preset to provide a desired camber and caster adjustment when mounted on the steering structure in a predefined orientation.

Abstract: Camber is adjusted in a strut-type suspension by replacing one of the two factory-installed bolts that holds the wheel onto the strut with a replacement bolt having a shaft portion that is narrower in diameter than the hole which retains the original bolt. A wedge is then inserted between the strut and the wheel mounting such that camber is adjusted with the wheel mounting pivoting about the remaining second factory bolt holding the wheel mounting to the strut. Preferably, the wedge has a threaded rod extending from the narrower portion of the wedge through a washer that is retained by a bracket holding the wheel mounting to the strut. A nut is threaded onto the bolt and works against the washer to pull the wedge between the wheel mounting and the strut to adjust camber and to retain the wedge between the wheel mounting and the strut.
