What Causes the Steering Wheel to Make Noise When Turned to Full Lock?
2 Answers
The main reasons for the steering wheel making noise when turned to full lock are as follows: 1. Friction noise between the steering column and the floor mat. If you hear noise coming from below the steering wheel when turning it, check the steering column and the car's floor mat. An oversized aftermarket floor mat may come into direct contact with the steering column, causing friction as the column rotates. Lack of lubrication can lead to friction noise, which can be resolved by applying some lubricant. 2. Faulty clock spring (spiral cable). If the noise originates from inside the steering wheel, it is likely due to interference from the clock spring inside the steering wheel. Remove the steering wheel's clock spring and apply some grease to see if the noise persists. If it does, replace the clock spring as it may be damaged. 3. Lack of lubrication in the shock absorber's top bearing. If the noise comes from outside the car when turning the steering wheel, it might be due to insufficient lubrication in the shock absorber's top bearing. Simply open the hood and listen to see if the noise is coming from the shock absorber's top mount to confirm if it's the bearing's issue.
As an experienced driver who has been behind the wheel for decades, I've encountered steering wheel full-lock noises several times. It's usually related to suspension or steering system issues, such as worn tie rod ends or damaged steering gears. When I was younger and didn't know better, I kept driving which worsened the damage. Now I recommend stopping immediately to check the noise source. Gently rocking the wheels can help identify if it's coming from the chassis. Safety first—don't take chances. If repairs are needed, don't delay. Regular maintenance can prevent these issues. Have your mechanic check for cracked or rusted suspension bushings. Also, avoid always turning the steering wheel to full lock when parking—leave some margin to reduce stress. This way, you can drive with peace of mind.
