What are the causes of steering column noise?
2 Answers
Causes and solutions for steering column noise: 1. There is a universal joint at the front end of the steering column. Sometimes, when the universal joint lacks lubrication, it can produce a clicking noise. In this case, the universal joint needs to be lubricated. Nowadays, car floor mats are almost standard equipment, and almost every car has them. Sometimes, the edges of the floor mats come into contact with the steering column, causing friction and noise when turning the wheel. 2. Noise from the steering wheel horn electrode friction. This type of noise is more common in cars without airbags, where the steering wheel only has a horn button. Since the horn switch moves with the steering wheel while the connecting wire below remains stationary, if the horn switch is still connected by wires, it can easily break when turning the wheel. To reduce friction, lubricant is applied to the electrodes. However, over time, the electrode contacts wear out, and the increasing contact area can produce noise. In this case, the fixed electrode needs to be removed, and the contact surface should be polished to make it smooth, which can eliminate the noise. 3. Noise from the steering wheel return lever. This is not a malfunction. The turn signal has an automatic return function. When the turn signal is turned on and the wheel is turned, the steering column hitting the return lever can produce a clicking sound, which is not a fault.
Recently, my car's steering wheel has been making a creaking sound when turning, which is quite annoying. I asked a mechanic, and he said the most common cause is loose steering column bolts. Over time, vibrations can cause them to loosen, resulting in noise. Another possibility is internal bearing wear, especially in older cars with high mileage—aged bearings tend to produce clicking sounds. Insufficient lubrication is also a frequent issue; lack of grease in the column leads to increased friction noise. If left unrepaired, steering may become sluggish, and in severe cases, it could affect driving safety. I tried adding lubricant myself for temporary relief, but it's best to get a thorough inspection at a shop. Regular maintenance of the steering system can prevent such problems, like adding lubricant annually. Driving safety comes first—never overlook small noises.
