What causes the steering wheel to make noise when turning left but not when turning right?
2 Answers
The reasons for the steering wheel making noise when turning left are as follows: Generator failure: Unstable power supply can cause abnormal steering. Loose connections in the power steering system may lead to leakage of some steering fluid. Power steering pump failure: Damage to the power steering pump can also cause abnormal steering. Air in the steering system may result in steering anomalies. Check all connection points for any looseness. Steering gear piston cylinder mechanical damage: Mechanical damage to the steering gear piston cylinder, decreased sealing performance of the oil seal, or damage to the control valve. If there are foreign objects in the steering hydraulic lines, they may cause the steering pump flow control valve to stick.
My old car recently had this issue where the steering wheel would creak when turning left, but was fine when turning right. At first, I thought it was minor and ignored it, but the noise became increasingly noticeable, especially during slow turns in the garage—it was really grating. A mechanic friend took a look and found that the ball joint on the left front wheel's tie rod was worn out. He explained that because the forces during turns and shock absorber compression differ, the left-side components tend to wear out first. He advised parking farther from curbs to reduce uneven stress and to get any unusual noises checked early. Otherwise, if the tie rod fails completely, it could be dangerous, and replacing the entire steering system could cost thousands more.
