What Causes the Steering Wheel to Make Abnormal Noises in a BMW?
2 Answers
The reasons for abnormal noises when turning the steering wheel in a BMW are as follows: 1. Reason one: If the noise comes from below the steering wheel, it might be due to the steering column dust cover. Applying some grease inside the dust cover can eliminate the noise. 2. Reason two: If the noise originates outside the vehicle, it could be caused by insufficient lubrication in the shock absorber's plain bearing. Applying grease to the plain bearing may help, but if the noise persists, replacement is necessary. Relevant information about BMW is as follows: 1. Detail one: The dimensions of the BMW long-wheelbase version are 5087mm in length, 1868mm in width, 1500mm in height, with a wheelbase of 3108mm. 2. Detail two: It is equipped with passive pedestrian protection, zero tire pressure continued driving, fatigue driving alert, electric trunk, active grille shutters, steering wheel memory, full LCD instrument panel, etc.
I've noticed that unusual noises when turning the steering wheel are quite common in BMWs, usually related to components of the steering system. When the universal joint or bearing of the steering column lacks lubrication, it produces a squeaking sound, especially noticeable during low-speed turns. Another critical factor is the thrust bearing at the top of the shock absorber; once it ages, it emits a clicking noise, most apparent when turning the steering wheel right after a cold start in the morning. Additionally, worn horn contacts or the clock spring inside the steering wheel can create a sandpaper-like sound similar to a mouse wheel. Insufficient pressure from the power steering pump might also cause a humming noise during turns, in which case you should check if the power steering fluid is leaking or degraded. If the car also vibrates, the ball joints in the suspension system should be inspected. These issues are not just annoying; neglecting them can lead to increased wear over time. I recommend using a stethoscope to pinpoint the source of the noise as soon as possible for targeted repairs.
