Vehicle alignment will not correct

• A. Camber
• B. Caster
• C. Pinion angle
• D. Toe

Answer: (C)

Wheel alignment focuses on how the wheels sit in relation to each other and to the vehicle, specifically adjusting camber, toe, and caster to meet specification. Camber is the tilt of a wheel inward or outward, toe is how much the wheels point in or out at the front, and caster is the forward/backward tilt of the steering axis that affects steering feel. Pinion angle is different: it’s the angle between the driveshaft and the pinion gear, a driveline geometry issue that depends on suspension height and driveline setup. Adjusting toe, camber, or caster doesn’t change this driveline angle, so an alignment won’t correct pinion angle. If the driveline angle is off, the fix is to adjust the driveshaft/driveline setup or suspension layout, not perform a wheel alignment.
