Camber is the measure of wheel tilt from the vertical direction, when the wheel is viewed from the rear of the vehicle. Camber is negative when the top of the wheel is inboard and positive when the top is outboard. Always check for bent, damaged or worn suspension components before determining that adjustment is necessary. The amount of tilt is measured in degrees from the vertical and this measurement is called the camber angle.
On 2wd vehicles, camber is adjusted by removing or adding shims at both front and rear pivot shaft-to-frame contact points. To increase camber, subtract shims equally from both locations. On 4wd vehicles, adjustment is once again made using the adjustment cams.
