What Causes the Steering Wheel to Make Abnormal Noises When Turning?
1 Answers
Abnormal noises when turning the steering wheel may be caused by the following reasons: 1. Lack of lubrication in the shock absorber top bearing: If the noise is heard coming from outside the vehicle when turning the steering wheel, it might be due to insufficient lubrication in the shock absorber's top bearing. 2. Loose stabilizer bar bushings: If the noise does not originate from the shock absorber's top bearing, check if the stabilizer bar bushings are loose or damaged. Loose or damaged stabilizer bar bushings can cause noises not only when turning but also when driving over uneven roads. This issue can often be resolved by adding shims. 3. Dirty power steering fluid: If the power steering fluid is too dirty, it increases the pressure in the power steering system, leading to a "buzzing" noise from the power steering pump. It is essential to replace the power steering fluid promptly. 4. Aging of the tie rod end ball joint: If the tie rod end ball joint is worn out, it can cause the steering wheel to shake and produce noises. In such cases, the tie rod end ball joint should be replaced, followed by a four-wheel alignment.
