Why Does the Rear Steering Knuckle of the LaCrosse Make Abnormal Noises?
1 Answers
The abnormal noise from the rear steering knuckle of the LaCrosse is a chassis issue. Possible causes of the abnormal noise from the rear steering knuckle of the LaCrosse: Failures in components such as the steering gear, power steering, and chassis parts, including outer CV joint failure, shock absorber failure, aging of related ball joints, excessive clearance, as well as power steering pump failure, insufficient or deteriorated power steering fluid, etc. Additionally, rust on certain ball joints, such as the control arm ball joint, can also cause abnormal noises when the car is turning. Abnormal noises when turning the steering wheel: If abnormal noises are heard from below the steering wheel when turning, check the steering column and the car floor mat. If the aftermarket floor mat is too large and directly contacts the steering column, friction will occur as the steering column rotates. Lack of lubrication can lead to friction noises, which can be resolved by applying some lubricant. If the noise comes from inside the steering wheel, it is often caused by interference from the airbag clock spring inside the steering wheel. Remove the steering wheel airbag clock spring and apply some grease to see if the noise persists. If it does, replace the airbag clock spring as it may be damaged.
