Alignment Screen Preparation

Fig. 2 Headlamp Alignment Screen - Typical:

1. Position vehicle on a level surface perpendicular to a flat wall 7.62 meters (25 ft.), export vehicles use 10 meters (32.8 ft.), away from front of headlamp lens.
2. If necessary tape a line on the floor 7.62 meters (25 ft.), export vehicles use 10 meters (32.8 ft.), away from and parallel to the wall.
3. Measure from the floor up 1.27 meters (5 ft.) and tape a vertical line on the wall at the centerline of the vehicle. Sight along the centerline of the vehicle (from rear of vehicle forward) to verify accuracy of the line placement.
4. Rock vehicle side-to-side three times to allow suspension to stabilize.
5. Jounce front suspension three times by pushing downward on front bumper and releasing.
6. Measure the distance from the center of headlamp lens to the floor. Transfer measurement to the alignment screen (with tape). Use this horizontal line for up/down adjustment reference.
7. Place a tape line 130 mm (5.12 in.) below parallel to center of headlamp line.
8. Measure distance from the centerline of the vehicle to the center of each headlamp being aligned. Transfer measurements to screen (with tape) to each side of vehicle centerline. Use these lines for left/right adjustment reference.
