What Causes the Chassis to Make Noise When Turning the Steering Wheel?
3 Answers
The main reasons for chassis noise when turning the steering wheel: 1. The steering column lacks lubrication, resulting in high friction. 2. Check if the power steering fluid is low. 3. Inspect the universal joint for any issues. 4. The rubber bushings of the chassis suspension stabilizer bar links may have aged and hardened. 5. The plane bearing may be damaged. Relevant information about the car steering wheel is as follows: 1. Function: Its function is to convert the force applied by the driver to the edge of the steering wheel into torque and transmit it to the steering shaft. 2. Correct grip: If the steering wheel is viewed as a clock face, the correct hand position is to place the left hand between the 9 and 10 o'clock positions and the right hand between the 3 and 4 o'clock positions. In the event of a collision, this posture is more conducive to supporting the body.
I've encountered the issue of squeaking noises from the chassis when turning the steering wheel several times. Initially, I thought it might be a tire problem, but after inspection, it turned out there might be a fault in the power steering system or worn ball joints. Loose suspension bolts can also easily cause abnormal noises, especially noticeable during low-speed turns or parking. Last time my car had this issue, the mechanic diagnosed it as aging and cracked suspension bushings that needed replacement. Ignoring these sounds could lead to unresponsive steering, posing significant safety risks. I recommend you first find a safe place to park, gently turn the steering wheel to locate the source of the noise; if you don't have tools on hand, don't force it, and get it checked at a professional shop promptly to prevent minor issues from becoming major problems. A friend of mine almost had an accident because they didn't get it fixed and now doesn't dare to take it lightly.
Years of repairing cars have shown me that steering wheel noise is a frequent concern. There are typically three causes: first, a faulty power steering motor or sensor causing gear friction sounds when turning; second, worn suspension arm ball joints or bushings that squeak during turns; third, loose chassis bolts or shock absorber issues, especially noticeable on bumpy roads. A simple diagnosis: start the car, turn the wheel to listen for noise location, or turn off the engine and manually shake the wheel to check for looseness. I've seen many cases where severely worn ball joints lead to heavy steering or even loss of control. Don't delay on safety—if you can't fix it yourself, visit a repair shop. Regular suspension maintenance can prevent these issues. Remember to test in a quiet area and avoid troubleshooting at high speeds.
