What Causes the Steering Wheel to Squeak When Turning?

[McKinsley]

The reasons for a squeaking sound when turning the steering wheel are as follows: 1. If the noise occurs when turning the wheel while stationary, it is likely due to the friction between the spring steel plate of the horn wire transmission and the steering wheel. The sound usually comes from inside the car and is a rustling metal friction noise. The solution is to apply some lubricant to the contact area between the spring steel plate and the steering wheel. 2. If the noise occurs while driving, the sound usually comes from the front suspension outside the car. 3. If the sound is a sharp squeak, it is likely caused by excessive or insufficient front wheel toe-in, resulting in tire scrubbing due to non-parallel turning of the front wheels. 4. If the sound is a clicking or rattling noise, it is probably due to excessive wear of the car's half-shaft CV joint. Typically, a noise when turning left indicates damage to the right-side CV joint.
