Abstract: The present invention provides, in at least one embodiment, a portable wheel alignment and weighing system and device having a hub adaptor that attaches to the bolts of a wheel hub assembly after the wheel is removed, having a plurality of novel independent rolling wheels allowing the suspension to settle before measuring parameters, having a plurality of optical sensors for measuring the alignment parameter before, during, and after the adjustment. The wheel alignment device eliminates the need for a slip plate through the plurality of independent rolling wheels, eliminates the need for a big and costly alignment rack due to its portable nature, improves alignment accuracy due to measurements being performed on the suspension directly without the tires on, and allows for faster alignments due to live adjustments, since the mechanic is allowed full access to the adjustment location.
