Operation CHARM: Car repair manuals for everyone.

Notes

Rear wheel toe is the only adjustable angle. If camber is not within specifications, inspect for worn or damaged rear suspension components.

Before checking rear trim height or measuring rear alignment angles, the following procedure should be performed to ensure the rear air-adjustable struts are filled with residual pressure only.
1. Place a weight of at least 300 lbs. in vehicle trunk.
2. Turn ignition On, then wait for the "vehicle leveling" light to illuminate.
3. Turn ignition Off and remove weight from trunk.
4. Wait at least 30 seconds for ELC system to exhaust.
5. Roll car forward or backward several complete tire rotations to eliminate the effects of tire camber change.
6. Jounce front and rear bumpers 3 times to normalize suspension prior to measuring angles.
