A vehicle wheel alignment method and tire force measuring system is disclosed which enables lateral forces generated by a vehicle tire so that vehicle alignment adjustments may be made to compensate for these as well as other tire generated forces or to enable matching of tires on a given vehicle axle to compensate for such forces. The apparatus provides a pair of tire supporting rollers each of which is supported for independent lateral movement and together are supported for movement in a horizontal plane. In this way, forces resulting from conicity and ply-steer may be measured in addition to the forces from camber and toe in which have been measured in the past. Once the magnitude and direction of these forces has been determined suitable adjustments to the vehicle suspension system may be made so as to net the given force to substantially zero for a given axle.
A system and method is presented for a putter grip having a lower section that is free to both rotate and axially slide along the putter shaft. In the preferred embodiment, this lower grip section slides and rotates over a core upon which is mounted an upper grip section that does not move relative to the putter shaft. The lower grip section is restrained in its axial movement to a portion of the putter shaft through the use of movement stops.
A method of aligning front wheels of a vehicle so that the steering wheel of the vehicle is centered when the vehicle is driven including the steps of aligning the front wheels in centered positions corresponding to straight ahead driving while the steering wheel is immobilized in a centered position likewise corresponding to straight-ahead driving and then turning the steering wheel from a first off-center position through its centered position in a first direction and from a second off-center position through its centered position in an opposite second direction with at least a fraction of the weight of the vehicle on the front wheels. The method according to this invention further includes the steps of recording first and second off-center angles of the steering wheel relative to its centered position at the instants the front wheels achieve their centered positions as the steering wheel is turned in the first and second directions and then adjusting the front wheels relative to the steering wheel through equal included angles proportional to one half the difference between the first and second off-center angles of the steering wheel.
