Total Vehicle Four-Wheel Alignment
1) Check that both Laser Toe Gauges are level. The laser beams should be visible on the rear Retro-screen
mirrors.(See Fig. 38)
2) Rotate the rear Retro-screen assemblies out of level if necessary, so that the laser beams will be reflected
back to the front Toe Gauges and be visible on the Thrust Angle Scales.
3) Note the reading on each of the Thrust Angle Scales. Adjust the toe of each rear wheel until the laser
beam image on the corresponding Thrust Angle Scale is in the middle at the number 5. (See Fig. 39 and
Fig. 40)
This completes a four-wheel alignment.
