Which adjuster position changes caster without changing camber?

The 90° and 270° slot positions produce 0 camber change; 90° adds positive caster (+0.5, +1.0, or +1.5 depending on adjuster size) and 270° adds negative caster on both axles.

What adjuster sizes are covered in the table?

Three service adjuster types: 1/2 degree, 1 degree, and 1-1/2 degrees.

Is the hole in a zero-degree adjuster offset?

No. The note states the hole is centered on a zero-degree adjuster, it is not offset as shown in the diagram.

How is the adjuster oriented in the diagram?

The diagram is a top view of the camber/caster adjuster with 0° toward the front of the vehicle, and slot positions marked every 45° from 0° to 315°.

This document is a 'Camber Cam Rotation Offset' reference chart for front-end alignment using camber/caster adjuster cams (bushings). A top-view diagram of the camber/caster adjuster shows how the position slot in the axle corresponds to degree markings from 0° to 315° in 45° increments, oriented relative to the front of the vehicle. A note clarifies that the hole is centered on a zero-degree adjuster and is not offset as shown in the drawing. The main table lists three service adjuster types (1/2, 1, and 1-1/2 degrees) at each of eight slot positions (0°, 45°, 90°, 135°, 180°, 225°, 270°, 315°) and gives the resulting camber change and caster change, in degrees, separately for the left-hand (LH) and right-hand (RH) axles. For example, a 1-degree adjuster at 0° gives -1.0° camber change on the LH axle and +1.0° on the RH axle, with no caster change; at 90°, camber is unchanged but caster changes +1.0° on both sides. This allows a technician to select the proper adjuster size and rotation angle to achieve desired camber and caster corrections during a front alignment.
