What symptoms indicate that a car's steering gear needs replacement?

[StJude]

Car steering gear needs replacement when there are abnormal noises or unusually heavy steering while driving. Specific manifestations of steering gear failure: Abnormal noises occur when turning the steering wheel while stationary; noises are present both when stationary and when driving at speeds not exceeding 20KM; the steering wheel is very loose when turning or extremely heavy and difficult to turn. Typical power steering pump failure can cause difficulty in steering, resulting in unusually heavy steering while driving. Methods to protect the car's steering gear: Avoid turning the steering wheel while stationary; try to steer only after the vehicle is moving; stationary steering should only be used occasionally in special circumstances like maneuvering out of a parking spot; when the vehicle is parked, the steering wheel should be returned to the central position to avoid putting load on the suspension system and tires; when making a U-turn, try to avoid turning the steering wheel to the extreme end position.
