Technician A claims that cross caster could cause tire wear. Technician B says it could cause a pull. Who is correct?

Cross caster refers to a condition where the camber of the wheels is not uniform across the axle, typically where one wheel has a different camber angle than the other. This misalignment can cause uneven distribution of forces acting on the tires, which leads to tire wear.

However, the more notable effect of cross caster is that it can cause the vehicle to pull to one side. This is because if one wheel has more positive or negative camber compared to the other, the tires will grip the road differently, creating a directional pull.

Thus, when Technician B states that cross caster could cause a pull, this accurately reflects the primary impact of this condition. The statement highlights that the difference in camber angles can lead to compromised steering stability and directional control. Therefore, Technician B is correct in asserting that the misalignment can produce a significant pull, while Technician A's assertion about tire wear, while related to alignment issues in general, does not specifically encapsulate the predominant effect of cross caster.
