ASE A4 Suspension and SteeringWheel Alignment Diagnosis, Adjustment, and RepairEasy
A technician is performing a four-wheel alignment on a vehicle. The alignment machine displays a front left camber of -0.8 degrees and a front right camber of +0.2 degrees. The specification for camber is 0.0 degrees ± 0.5 degrees. Which of the following statements is true regarding the current camber readings?
- ABoth front camber readings are within specification.
- BThe front left camber is out of specification, and the front right camber is within specification.
- CBoth front camber readings are out of specification.
- DThe front left camber is within specification, and the front right camber is out of specification.
Show answer & explanationAnswer & explanation
Correct answer: B. The front left camber is out of specification, and the front right camber is within specification.
The specification is 0.0 degrees ± 0.5 degrees, meaning the acceptable range is -0.5 to +0.5 degrees. The front left camber of -0.8 degrees falls outside this range, while the front right camber of +0.2 degrees is within the range.
Why the other options are wrong
- A. The front left camber of -0.8 degrees is outside the acceptable range of -0.5 to +0.5 degrees.
- C. The front right camber of +0.2 degrees is within the acceptable range.
- D. The front left camber is out of specification, not within.
Camber Specification
Camber specification defines the acceptable range (usually in degrees) for the inward or outward tilt of the wheel relative to the vertical axis.
- Positive camber: top of the wheel tilts outward
- Negative camber: top of the wheel tilts inward
- Specifications include a nominal value and a tolerance (e.g., 0.0° ± 0.5°)
Memory trick: Remember the 'in or out' tilt, then check the 'plus or minus' range.
