ABSTRACT:
A wheel alignment process using manually operable alignment apparatus wherein all four wheels of a vehicle having a front steerable wheel pair and a rear nonsteerable wheel pair may be set in toe without turning the vehicle around part way through the process. The process provides for setting both front and rear toe relative to the chassis centerline in one aspect of the disclosure and for setting rear toe as close as practical to the chassis centerline and the front toe relative to the rear wheel rolling direction in another aspect of the disclosure. A lock is also disclosed which assures stability of the reference for the front and rear toe settings during the practice of the toe setting process.
