What Causes the Steering Wheel to Make Noise When the Nissan Sylphy Goes Over Bumps?
2 Answers
The main reasons for the noise are as follows: 1. The steering column is not lubricated, resulting in high friction. 2. Insufficient power steering fluid. 3. Issues with the universal joint. 4. Aging and hardening of the rubber bushings on the suspension stabilizer bar links. 5. Damage to the wheel bearing. Note: If you notice noise from the steering gear while driving, it's best to find a safe place to pull over. If the noise is severe, it's advisable to call for a tow truck. If the noise only occurs on bumpy roads or comes and goes, you should promptly reduce your speed, avoid making sharp turns, and drive slowly to the nearest 4S shop or repair facility for inspection. Do not continue driving under risky conditions.
I also drive a Nissan Sylphy, and when going over bumps, there's an abnormal noise from the steering wheel. There could be several possible reasons: the bearings or bushings inside the steering column are worn out, causing a squeaking sound over bumps; the ball joints or connection points in the suspension system are loose, producing a knocking sound when driving on rough roads; the gap in the steering rack and pinion has increased, which can also cause a clicking noise; or it could be that the upper strut mount bearing is damaged, leading to impact noises in the steering system. This issue might sound like minor noise, but ignoring it could accelerate component wear and affect steering response and safe driving. It's recommended to first observe the pattern of the noise—if it only occurs on normal bumps on flat roads, it's likely a suspension or steering problem. Take it to a professional repair shop promptly for a diagnostic check. Pay more attention to lubricating these areas during maintenance; preventive measures can save a lot of money, and safety should always come first.
