Lower Control Arm Documentation
With the Matrix Wand you can quickly, easily and accurately measure and diagnose complex suspension problems, we call this "Predictive Wheel Alignment." In this example the technician wanted to document the lower control arm, at the ball joint. Using the Wand we imaged the lower body and measured the appropriate points. As you see by comparing the blue diagonal measurement (1222mm) to the orange diagonal measurement (1234mm) the difference is -12mm back on the diagonal distance.
When you compare the red and green distances they are essentially equal at (915mm). These measurements show the outward distance at the ball joint is symmetrical.
Additional measurements where then taken to find the source of the ball joint and lower control arm variance. We quickly found that the front trailing arm was back due to body damage, while the trailing arm itself was undamaged.
