Technician A says bump steering can cause the vehicle to dart and dive from side to side after hitting a bump. Technician B says a positive degree in the thrust angle can cause a vehicle to "dog track" as it goes down the road. Who is correct?

Question

Quizplus · Accepted Answer

Both technicians are correct. Bump steering occurs when the vehicle's suspension cannot adequately absorb the shock of hitting a bump in the road, causing the vehicle to dart and dive from side to side. Meanwhile, a positive degree in the thrust angle means that the rear wheels are pointed slightly to one side, causing the vehicle to "dog track" or move off-center from the direction it is steered.
