What Causes the Steering Wheel Noise When BMW 3 Series Turns in Place?
2 Answers
BMW 3 Series steering wheel noise when turning in place is caused by lack of lubricant in the screws inside the steering wheel, or potential failure of the steering gear. Below are the reasons and solutions for the steering wheel noise in BMW 3 Series when turning in place: Lack of Lubricant in Screws: If there is a lack of lubricant in the screws inside the steering wheel, the steering wheel cover needs to be removed to add lubricant. This should make the tracks and pivots smoother, resolving the issue. Steering Gear Failure: The steering gear may malfunction. If the steering wheel is turned too sharply during normal driving, it increases the load on the steering gear, leading to severe wear and noise. It is recommended to inspect and replace the faulty parts. Coupler Oil Not Replaced: If the coupler oil has not been replaced for a long time, it can cause imbalance or shaking. It is advisable to check whether replacement is necessary. Uneven Tire Pressure: Uneven tire pressure in the left front or right front tire can cause the front of the car to pull to one side, resulting in unbalanced wheel bearings, misaligned steering gear, noise, and pulling.
As a veteran driver with decades of experience, I've encountered the issue of BMW 3 Series making squeaking noises when turning the steering wheel in place quite often. The main cause is usually a problem with the steering system, such as aging or insufficient lubrication of the small motor in the electric power steering module, which creates a squeaking sound when turning. It could also be due to wear in the ball joint of the tie rod, causing friction noises when steering. If left unattended, the steering will become increasingly heavy, and in severe cases, the steering wheel might even lock up, which is extremely dangerous. I must remind you that BMW's electric power steering system is complex, so don't attempt DIY repairs. Take it to an authorized repair shop for inspection immediately. Safe driving is the top priority—spending a little now can prevent major repairs later. Additionally, during regular maintenance, check the steering fluid or lubrication condition to extend component lifespan and prevent minor issues from becoming major headaches.
