I've been driving a BMW E90 for several years, and the steering wheel occasionally squeaks, like an old car groaning. At first, I thought it was a minor issue, but the noise grew louder, especially when turning or going over bumps. After inspection, it was found that the universal joint in the steering column was severely worn and needed replacement; the ball joints and suspension bushings also showed signs of aging. The mechanic mentioned that the E90's steering system components are prone to vibration-related wear, especially in high-mileage vehicles. It cost me two thousand yuan to fix, but now the steering is quiet and smooth. I recommend not ignoring unusual noises—regularly inspecting and lubricating the joints can prevent issues. Avoid sudden steering movements while driving to extend part lifespan, as safety should always come first.
If you're a hands-on car owner, you can perform a preliminary check when your E90 steering wheel makes abnormal noises. First, park the car securely and try turning the steering wheel to locate the source of the sound: if it's a clicking noise, it might be a loose ball joint; a squeaking sound points to aging suspension bushings. Get under the car to check if the wheel hub nuts are tight and if the tire pressure is normal. I've personally tried replacing a faulty ball joint—there are plenty of tutorials online, and the parts cost just a few dozen bucks. Be careful not to touch the high-voltage electric power steering system to avoid accidents. After repairs, get a wheel alignment. It saves hassle and money while teaching you new skills, making driving more reassuring.
