Question

Quizplus · Accepted Answer

Both technicians A and B are correct. Excessive erratic steering effort on a cold power recirculating ball steering gear may be due to a worn ball nut piston ring (as mentioned by technician A) or scored ball nut piston cylinder (as mentioned by technician B). Both of these issues can cause uneven and erratic pressure distribution within the steering gear, resulting in steering difficulty.
