What Causes Abnormal Noise During Low-Speed Steering?
2 Answers
Low-speed steering abnormal noise causes: issues with the steering wheel airbag clock spring, aging of the tie rod end ball joint, loose or damaged stabilizer bar, problems with the shock absorber top bearing, improper tension or aging of the power steering belt. Detailed causes and solutions: Steering wheel airbag clock spring issue: This sound usually comes from inside the steering wheel. The solution is to apply some grease to the airbag clock spring. If the noise persists after greasing, the clock spring needs to be replaced. Aging tie rod end ball joint: In this case, besides noise, it may also cause vibration. The solution is to replace the tie rod end ball joint. Note that a wheel alignment is required after replacement. Loose or damaged stabilizer bar: If this is the problem, the noise will occur not only during steering but also on rough roads. The solution is to add shims or replace the stabilizer bar. Shock absorber top bearing issue: Lack of lubrication in the shock absorber top bearing can also cause such noise. The inspection method is simple: open the hood and check if the noise comes from the shock absorber top mount. The solution is to apply grease. If ineffective, the component needs replacement. Improper tension or aging of the power steering belt: For this situation, adjust the belt tension or replace the belt.
With over a decade of car repair experience, I can tell you there are only a few common causes for low-speed steering noises. If you hear a humming sound when turning, it's likely an issue with the power steering pump – either low hydraulic fluid or a clogged filter. A clunking noise usually points to problems with the strut mount bearings at the top of the shock absorbers, which often wear out after prolonged rough driving. Worn steering gear can produce similar clunking sounds, especially in older vehicles. Also, deteriorated rubber bushings at chassis connection points can create squeaking noises, much like rubber rubbing against surfaces. Sometimes, pebbles stuck in tire treads can be misleading too. My advice: don't delay. Get the car lifted for inspection early. Replacing small components like ball joints and tie rods is inexpensive, but waiting until the steering gear gets damaged will cost you dearly.
